Yamaha XTZ125, good news
Today I walked passed my local Yamaha dealer and I saw a little off-road bike there. Got curious so went in and it turns out that Yamaha is selling now a new enduro model. Its called XTZ125 and its pretty cool for RMB11000. If its an old news please forgive me but I didnt see this bike before.
Its an air cooled 125cc engine with a kick/electric start. 10L tank (400km???) and 26cm ground clearance. It comes with dirt tires and there are some decent Kenda or CST tires on taobao in RMB500-700 range.
Its a shame that it has a drum at the back and that it isnt a 250cc but nevertheless its an interesting lil bike and a good option for those guys who always come here asking about good bikes to travel around China on. I was considering X2 but this might be a winner for me
Tere are not many accessories on taobao yet but it shouldnt be long now. Some good skid plate, handguards and its gonna be a good toy around the back yard.

Why not 250. So much potential to be the best of its kind in China.

Re: Yamaha XTZ125, good news
They are reactive to the market apposed to being proactive. The market has massing’s they sell into those. For example what does the market purchase the most of, in China it appears that once a certain income is attained then autos become the vehicle of choice. So as the engine size increases the market become smaller the consumers of motorcycles in China are actually price conscious and also require in that fuel efficiency. However it is an evolving market and very large, but it is also hyper competitive so profits are limited.
Yamahas partner Jianshe could consider the new 250 Tenere, however they seem to believe that a touring bike would be the best way to develop that 250cc single into the market?

Re: Yamaha XTZ125, good news
Modrod,
I saw the XTZ on the Yamaha website last weekend, I made a few enquires and I went down to my local Yamaha dealer Tuesday to place on order as they didn't have one in stock. So sometime next week I will be taking delivery of a blue XTZ 125. For me the only drawback is the lack of power, but after seeing that there are so many aftermarket engine kits and that these little engines can make more than 20 hp. I couldn't resist.
Yamaha has been selling versions of this bike in Europe and South America for a while, started selling recently in Indonesia as well. So it is tried and tested. The engine is almost the same as the YBR 125, the only difference that I have been able to lean is a different camshaft and carbd setting at least for the South American markets.
As soon as I receive I'll post a review.

What aftermarket kits would this bike take? Would you trust a Chinese mechanic to install it? This bike with more power is just what I'm looking for. But 125 isn't enough for the long distance trips I want to take in the future.

Re: Yamaha XTZ125, good news
There is so much available for the engine, just search for Yamaha TTR125 on the internet and you will find hundreds of links. The TTR 125 has the same engine, all the part you find on the interent can be used on an XTZ125's engine except the exhaust as the exhaust runs on the left hand side of the bike on the TTR. For the exhaust you can find quite a few options in Argentina or Brasil.
I have bought the XTZ for local use, some road use but mainly offroad, so as long as it will run along the roads at a comfortable 80 kph I will be happy. No fun at higher speeds on offradd tyres anyway. I
have already source some Kenda K270 and extra thick off road type innter tubes from TaoBao. My wishlist for the time being is as follows :-
- A 150cc or maybe even a 180cc big bore kit.
- Camshaft that gives me improved torque ( better for off roading )
- I'll buy an extra cylinder head and port the intake and exhaust ports to improve the flow
- Some sort of improved flow air filter and do some air box mods to improve air flow too
- Silencer - probably go with the Pro Tork Devil unit. From what I have read it is works well. A second choice would be a FMF silencer.
- I also need to take a look at the exhaust downpipe and do something about this if there is a restriction of some sorts.
- Either a VM 24 Mikuni or 26 Keihin Carb, suitable jetted to suit al the mods. There are quite a few internet resources to give baseline figures for the jetting
I don't want to go over the top with the modifications as I still want Yamaha reliabilty so if I can end up with a reliable 13 or 14 BHP that would be ideal.
I would not let a Chinese mechanic even blow up the tyres on my XTZ, I will do everything myself. Any machining ( such as for the 180cc conversion ) I will do at a friend's factory that has everything you can ask for.

Re: Yamaha XTZ125, good news
Hey Symon,
Hows the bike? did you manage to brake it in already? Any modifications done?
I think its going to be quite popular. Ive seen few of them on the streets of Taizhou already. Ive sat on one and it seemed a bit low, but it will do the trick.

Got the tee shirt done all what you are talking about with my YBR 125cc KG got 10KW and 22.7NM ? Made a big diffance to the bike but sadly it only lasted 13.000 km before on a long hard ride down to Thailand the engine went BANG it just can't take the power upgread so you will not be abel to keep the reliability of the standard engine IMO
Now in the process of fitting a Lifan 250 cc with a 6 speed boxs with 15 kW and 19 NM

Re: Yamaha XTZ125, good news
Hi Modrod,
I have been a bit delayed with my Yamaha as it took a while to get the number plates due to the CNY holiday, anyway I am now 100% legal with HuiZhou number plates and insurance.
I bought this bike mainly for offroading, I don't really enjoy riding on the roads. So far I have clocked up about 400 Kms, all but 40 kms have been offroad :-) It is perfect for what I want but lacking on power. The Suspension seems to work well both on and offroad and I will be leaving alone for while. The Kenda K270 tyres are great, grip well enough on road and so far have been very sure footed off road on hard pack, sand, mud and on rocks. I did go for a quick blast down to my local coffee shop ( 12 kms each way ) and the XTZ sits comfortably at a real 80 kph ( GPS confirmed ) and as such is fine for most of the on road riding I will do. Once I have done the engine modifications I will fit a smaller front gear to make my XTZ a bit longer legged to bring the engine speed down on the road. Should make it more reliable too.
After my second session I did a well documented air box modification ( same as a Yamaha TTR125 ), fitted a KM filter and rejetted the carb. This made a big difference as I can use a higher gear in most situations, using torque not HP. I will wait until may to do any more engine modifications as a customer will bring a Pro Tork exhaust for my XTZ from Brasil next month. As far as I can see Pro Tork is the only company that makes a full exhaust system rather than just a rear silencer. I have already sourced a TM24 Mikuni carb and a range jets to replace the original Mikuni that is not up to scratch and a BBR motorsport 150cc kit with an improved camshaft. Before the weekend I'm off to Hong Kong and i'm going to look for a proper set of handle bars ( the originals are already a little bit bent and some hand guards.
When I have done a bit more riding I'll do a proper report with photos ,and as I go along, I'll post the modifications and results in case they can help anybody else.
Anyway from my short time with the XTZ I am delighted with the bike, it has put up with everything I have thrown at it. Even done some trials type riding on some rocks I found. with a bit more power it will be great. I am sure that Yamaa will sell loads of these :-)
If the engine mods don't give enough I can always fit a YBR250 motor :-)

I am very surprised that you can have a true opinion on a bike with just 400 km
? Give it time and for sure the bike will break or some other shit will happen
I wish I could be wrong but time will tell , wish you luck and safe ridding .
Just 1 point "IF" you do the engine mods as you are talking about change all the engine bearing there are shit chinese made ones that will start to rattle in time ? Mine did ???
Love to hear how you get on with the bike please keep the forum updated if you can .

Re: Yamaha XTZ125, good news
Prince 666.
I said that from the short time with the XTZ that I was delighted, obviously a full opinion on my bike will take a lot more time. I had my last bike 14 years :-)
I have had lots of cars and a few bikes and of course anything will break over time, I hope that a Yamaha will give me a lot less grief than a Chinese bike. I have had quite a few Yamahas and they have all given me great service, I hope that this one is just as good.
What did you do to your Yamaha to get 10kw ? It will be interesting to see if your modifications are similar to my planned ones. You said you had problems with the engine bearings, anything else that gave you trouble ?
I plan to do my own maintainence as I have a lock up storeroom in the car park of the apartment block where I live, I need to work out a reasonable maintainence schedule to keep on top of things, so it would seem reasonable to strip the motor down every 10,000 - 12,000 kms to make sure all is well. I will take a look a good look at the engine bearings and replace with non Chinese ones.
I'll start a separate post on my bike as soon as work allows.
If you aever get down to HuiZhou please look me up, I always happy to share a beer with a fellow biker :-)

Re: Yamaha XTZ125, good news
You’re probably correct that when swapping out an engine, for the most part, it will not get noticed. However referring to the swap as making it legal is misrepresenting the literal meaning of the word legal. It’s a bit like saying driving over the speed limit is legal, until you get caught. If you swap an engine and then get in an accident, the probability of none noticing the engine was swapped, is it the same? Because in most legal systems it defaults you to operating it illegally and in that at fault in any accident. At fault simply because the alteration, noticed or not is in fact illegal.

Sorry Zorge when a member post a PM that I sent him and he post the PM on MCM which is strictly against forum rules and I have reported it so the post can be to removed and the same member. Fuck it let's not beat about the bush the member is PAL !!
And when this same member talks about the engine swap as be dodgy and posting condescending comments
I just say fuck it why should I post all the information and pictures I have on the YBR engine upgrade so PAL can make more condescending
Remarks !!
Happy to copy you in with the email just PM your email address
Hope you understand why I will not post the details !!

Its the same engine as the YBR125 so it will fit. Im thinking how much more oil, would have to measure the volume of the radiator

-
Re: Yamaha XTZ125, good news
Modrod,
I decided not to fit this oil cooler kit as I thought that the oil pipes could easily get caught up in branches or rocks when off road, I use Motul 7100 and so far I have had no indication of overheated oil.
BTW I have done a few mods to my XTZ, the main ones are :-
BBR 150cc kit with performance Camshaft
Protork Exhaust
Mikuni TM24
Programable Ingtech CDI, set up by yours trully
YZ250 46 mm forks, YZ 250 front wheel and brakes.
TTR125 Aluminum swing arm, shocker and pro link
I am running Kenda 778 tyres front and rear.
It has turned into a really nice bike, of course it is short on power but next summer I am planning to do a 194cc, 4 valve conversion using aftermarket parts for a Yamaha Zuma. That should get wake up the old girl.

Theres nothing really.
On Taobao there are kits to mount oil cooler like the one above and external oil filter connected to one of the hoses that goes to the radiator. Would have to figure out where to put that filter cos i recon it would rattle a lot hahah
Symon, PM on its way

Re: Yamaha XTZ125, good news
Actually I don't see a great problem about not having a removable oil filter, just change the oil often.

Oh man, it would be interesting thing to see, not just the final result, but even whole process. Symon, don't hesitate to share with the folks here how you managed to made this conversion.
About oil filtering element: I would be expected to see at least oil spinner because it is cheap to implement this thing. Even older engine designs than this "Yamaha's", such are "Honda's" horizontals, CBs and CGs have oil spinners who really picks up fine dirt that freely passes through the steel mash in front of the oil pump.
-
Re: Yamaha XTZ125, good news
Zorge.
Actually there is not that much to tell about the conversion, it is all quite straightforward.
I did all the engine stuff at the same time. The BBR 150cc kit and cam is an off the shelf item sold for the Yamaha TTR125, same engine as the XTZ. So just dismantle and refit with no dramas. The Protork exhaust system can from Brazil, a neighbour of mine exports Chinese bikes to Brazil and he knows the owner of Protork, so I got a on off, looks like standard, exhaust system which is considerably better than stock. There were a couple of issues fitting ( maybe the Brazilian XTZs are a bit different to the Chinese ones ) anyway nothing that a bit of cutting, welding and repainting couldn’t solve. I also was able to swop the original carb that was useless at making power with a Mikuni TM24. It bolted right up except I needed a new throttle cable ( from a TTR125 ) and a sneaky mod to make the front of the carb slightly larger in diameter to fit like a glove in the inlet manifold. I bought a few different jets and after a bit of trial and error I have got it dialled in nicely.
Then came the cheapest engine mod, lighten the flywheel. The original is just so heavy. Not sure how much it weighs now but the motor revs up a lot easier.
I thought the Yamaha CDI was holding back the bike, so a programmable CDi and a bit more of trial and error made a big difference.
Must be ok as the original motor struggled up to 80 kph and now it flies straight up to the rev limit which gives about 105 kph. It could easily be geared for more speed but I prefer to have a bit more acceleration off road.
Probably the worst thing about the XTZ when I bought was the original suspension and tyres. Tyres are an easy fix, I started with Kenda K270 and now I am using Kenda K778s. Both of which I highly recommend and have the advantage of being so cheap on Taobao. A really good mate of mine that travels regularly to Australia sourced a complete front end from a 2003 YZ250. It was in near pristine condition, I learned how to rebuild the forks from a Youtube video and fitted new bushes and seals. To get the YZ triple tree on to the XTZ was not as straight forward, I had to get the centre shaft machined to the same size as the XTZ so that I could reuse the XTZ bearings. I made a mess of the fork oils, firstly I used an oil that was far too thick and I didn´t read the workshop manual about setting the oil height. Anyway that got fixed with some Torco RSF Light oils and a bit more reading, but the front was still too stiff. A pair of 0.37 Eibach springs sported that out, the front end is now excellent. I used the YZ250 from wheel which is about half the weight of the XTZ one and of course the YZ brakes with some EBC pads. At the same time I fitted a set of EBC rear shoes from a TTR125 and the rear now stops well.
I sourced from Ebay a brand new rear swingarm, shocker and pro link of a TTR125 which apart from being a lot lighter that the original soaks up the bumps as well as the front. Of course it wasn’t a straight fit, I had to make and weld some brackets for the prolink to mount to the frame and as the TTR125 uses a 16” rear wheel I had to get the swingarm extended by about 2,5 cm
For the winter I will be using the XTZ as is, it is now a fun off road bike with enough power to actually climb hills and to get out of its own way. The suspension and brakes are really nice.
It seems that there is always something else to be done with this bike, I am ok with that as I enjoy getting my hands dirty and working stuff out. At the moment I need to source a Speedo drive and cable from a Yamaha WR450 to get the original speedo working again and I really should take her down to a rolling road to see if my trial and error set up is ok.
Over the summer ( when it is too hot to ride down here ) I will probably do the Yamaha Zuma cylinder and head conversion. It basically all bolts up except for a couple of hacks. I nice build to do on the kitchen table when the misses is away. I’ll need a bigger card, maybe a Mikuni TM 28 or 30 and then a bit of trial and error to get it running right. Like that it would be a pretty decent fun off road bike.

Re: Yamaha XTZ125, good news
Zorge,
Nowadays these conversions are quite easy as there is so much information available on the internet, i t's just a case of sifting through. This is my favourite thread http://planetminis.com/forums/bigger...ike-build.html
I am lucky that most of the XTZ is the same as a TTR125 and that there are so many aftermarket products available, E bay is a great source.
The biggest problem i have found is when you have to get others here in China to do something for me, just this morning I went down to the local machine shop to get a simple spacer made up. We spent more than 30 minutes trying to explain to them what I wanted only for the guy to say come back tomorrow. I told him it will take 10 minutes and that he should let me use the lathe. In the end I just told the machinist what to do and 10 minutes and 40 rmb later I had my spacers. I must give thanks for my every patient wife for helping me out.
I have been surprises by the amount of products that I have bought that don't fit, the last one was a BBR Cradle / Sumpguard, I had to cut and then get it rewelded. Wasted a whole morning ! And then some products have been 5 minute fits and work so much better than I expected, one of those was an AMS high out put coil.
I used to tinker around with cars when i was back in Europe, I only realised how much I missed it when I started to do stuff on my XTZ.
-
Re: Yamaha XTZ125, good news
Ha-ha-ha...! This your "spacers case" reminded me how much time took my attempt to make some... thingy which would help me to fit carb with flange type connector on a intake manifold intended for a carb with clamp type connector. Took me two weeks to organize foray on a machine shop guy, and after that, another week to find welder at home. Few more of my "projects", and I will be tempted to buy some Chinese lil' desktop lathe and mill. :icon10:
Nevertheless, don't be shy to tell us how you fitted 4V head on your bike.
-
Re: Yamaha XTZ125, good news
Zorge,
Sure, I'll let you all know how the 4V / Zuma engine conversion goes, I plan to start ordering parts after the CNY. I presume that I will have everything by the summer when I don't really want to ride my bike as it is far too hot for anything more serious than riding down to the beach for a late evening swim.
For the next 3 - 4 I just want to ride and enjoy after spending too much time fiddling with the XTZ, I do plan to get a lot of riding done during the CNY. How about a road trip to the other end of Guangdong ( to my wife's howm town ) and while the rest of the mob are playing Mahzhong or eating something that looks like it came from Kronos I'll get out and explore some of the small country roads and tracks I have seen on previous trips to the area.
-
Re: Yamaha XTZ125, good news
Symon, while we are waiting for this 4V conversion, if it isn't to much trouble for you, can you share with us some of your thoughts and impressions about this programmable CDI you bought?
