Honda CT70 Clones.

BKACKDEATH: It has a 32 tooth rear sprocket, and yes stilk has the original exhaust with emmission controls.

That's pretty good mph, I need to get an 18 tooth for my clone also.
I run a 17/29 on 8" wheels in a z50 clone.
I GPS my bike and got 60mph and I think that's all she's got.

60 is a pretty good speed, does it feel more on 8 inch wheels. If i can get mine to cruise st 50 i would be happy.

[BLACK DEATH]

It feels ok I'd say but I have to keep both hands on the bars or it gets a lil squirrly.
One hand off and it shakes a bit.
At that speed it feels very fast for being on a small bike.
I ride sport bikes also so this little bike is fun.

I don't want you to hurt anything else--so maybe when you have both hands and clear roads (and nicer weather, too) before testing your 50 cruising speed. My guess is you should be there, if you are hitting over 55 (with a 32 rear sprocket and stock exhaust)...

Welcome to here, Blackdeath! I wonder if the Loncin 125 engines have room for a 18 tooth, or will you have to file away to make room like Trex had to do on his Lifan 110??

I have the 125cc engine in the CT70 and Z50 clones and filing/grinding would be required to fit the 18 tooth. I personally don't think it is worth it. My stock 125s with 17 tooth front both top out at 55 MPH GPS and a reasonable cruise is 45 MPH.

[BLACK DEATH]

Yeah I'm pretty sure ill have to grind also as others have talked about it on other forums.
It's cheaper to replace the front sprocket than the rear.
But a smaller rear sprocket looks good on the rear, especially if you have nice rims.
I may buy an 18 tooth just to try it out, it's only $10 for one & my chain length may work

If/when I get my CT70 clone, 18 tooth is out (I would not trust my ability to file !) Do they have a decent selection of aftermarket rear sprockets, then?

IMHO I think that the 17 is enough of a jump up from the stock 15. More speed needs more motor or a different bike.
