hey guys, i was wondering what i should expect from a 60 tooth rear sprocket on a 26 inch wheel, i have a 66cc engine 2 stroke on my bike and its running very well, how fast should i expect to go if my engine does 7000 rpm's? and how will the torque be? im looking for more torque. thanks

Well, you'll definitely get a lot more torque. Probably too much. And this is coming from a guy who believes in going slow.

But a 60 tooth rear sprocket --I didn't even know that such a thing is available-- will, I think, be even too slow for me.

You'll likely have enough torque to pull away from a dead stop on engine power only. But I'm afraid that that engine will be simply screaming at, say, 12 mph. Let's call that 20 kph.

60T at 7000 rpm would be 21 mph according to my crap calculations. All I know is that with a 36T 5mph is 1000 rpm. So I just divided 36 by 60 then multiplied by 35 to get my answer.

whats the point? I live in san francisco, there are hills all over the place. I put a 52 tooth sprocket on my bike and it was way too much gear - all the torque you could want. Seriously a 48 would probably feel about the same with way more top end.

with my engine running a 36 tooth sprocket on the rear my bike could easily take off from a dead stop up a hill, i i will have 3 sprockets after my 60 tooth sprocket comes in the mail, it was incredibly hard to find a sprocket that big haha, im just glad i did find it, do you guys think ill be able to do wheelies?

do you guys think ill be able to do skids on gravel? just by pulling the throttle and leaning forward? i think with that much torque it will do it
