GREHUA Upgrade #35 Chain 60 Tooth Rear Drive Sprocket Cog for 98cc 3.5hp Coleman CT100U CC100X Baja Hensim Doodle Bug DB30 Motovox MBX10 MBX11 MM-B80 Classic 1000w Electric Mini Bike Go Kart Parts

Item was easily installed, fit perfect on my FRP mini bike. Have had for over a month and still holds great. Improved my top speed.

I had a 44 sprocket so it really gave me that extra torque I needed. Also really easy to install.

Worked great on my mini moto 80 with a 212 swap. Gave it way more top end speed. Torque was not much less. Solid quality.

works good but you have to keep chain really tight or it will fall off. The teeth are not deep enough. But it was inexpensive and arrived quickly.

Saw some reviews stating that it had too shallow of teeth and was throwing the chain. We thought we were having the same problem, but it turned out that we just shouldn't have removed the chain tensioner wheel on our FRP GMB100. Put the tensioner back on and makes it less apt to wheelies with the predator 224 swap and gives about an extra 12mph top speed. We did use it before the engine swap, but it made the little 98cc work way too hard to start moving or climb hills of any kind

Don’t waste your time it’s close but it’s not it the center hole is too small not a big deal little sand paper got it on then 1 of the 6 holes are off enough to mess the bolt up just to find out the chain doesn’t even seat down enough to use not only would I like a refund your product messed my hub up you owe me money absolute thumbs down

This one makes my chain fall off, i think it needs the teeths slightly taller & it will be a good sprockets. Had to go with the stock one. But if yours dont fall off, its a good one

So far so good. Put on coleman ct100u and it did what I needed, gave me 10 MPH more than stock with a 12 tooth clutch and factory rear sprocket.
