Hello people,
can anyone advise on buying the Motrac 250r?? It is fast?Dohc Engine? It's going to be my first bike and its 3 times cheaper than a CBR250.

Thanks

I've seen teh 125 version in the UK looked and sounded good not sure how the 250 would perform though.

Jiajue makes those, they come with either a 4-valve SOHC Zongshen or a DOHC 4-valve.
The later is considered a good engine, the former has not been reviewed its relatively new.

according to their website the R11 has the DOHC 250 the other models seem to have the SOHC which is rated with more power.

I see. I'll check with the agent selling these here to know which engine it is. But about parts,will honda cbr parts fit this bike? The agent is only 1 year knew,so availability of spare parts could be an issue.

Also the one I've found is a 5 speed bike, 1 down and 4 up. Ive been reading about the bike on the forum,and I think it was mentioned somewhere it has a 6 speed gearbox.

65.5x66.2 equates to 223cc of cylinder displacement.

This is a photoshop right or she's a midget? 200CC and this thing is huge! 12kw... My daughter wouldn't ride this.

That larger air cooled engine adds 15kg (33lbs) over the 125cc original YZF-R125.
It adds only 1kw of power but it has significantly more torque then the 125cc.

marketing images...

Too funny….

I had this bike for almost a year. Recently sold it. It's a really low quality frame FYI. It seems to run decent though. I put 150km on it a week. The brake disks are easy to warp. I would certainly replace them and the pads right away. It came with the hardest tires I've ever seen. Was like riding on plastic so I would get new tires. I beat the hell out of it. My buddy still rides it. It has never had a serious mechanical problem. It took two accidents with minor damage and was back on the road in days. All in all, a great buy for the price. Cosmetic upgrades are easy to get. Even new plastic because it sits on a very popular generic tubular steel frame. Parts were super cheap from the dealer. If you but it, make sure you go through the entire bike and tighten all the bolts. Everything was coming loose when I first got it... Everything
