CDHPOWER Multifunctional 56 Teeth Sprocket for 415/415h chain -2 Stroke Gas Engine Motor Gas Motorized Bicycle

Heavy duty feel. Lots of mounting options. Working great for my briggs and stratton build.

Made very nice

Works good.

Worked excellent on my 80cc bike build, only thing to consider is the size of the sprocket. You will need to buy extra chain and this sprocket maxes out at around 10mph. Lots of bottom end torque but no top-end.

Love it, crazy torque for those hills.

Great quality, fits perfectly, versatile. I've used it on 2stroke and 4 stroke applications. Works with hub adaptor,mag wheels and spoke mount applications

So this would get five stars if he had just MENTIONED that the inner 6 hole pattern can't be used with ANY conventional bicycle design. In fact to use a 6-hole hub to mount a sprocket, you have to cut a 2.5" center hole in the sprocket, to fit a separate disc/sprocket adapter. That adapter is about $29 with Prime. So if you were planning to use this sprocket directly on a disk hub forget it. You'll have to use the hub mount, or the rag (spoke breaker in sand) mount. For either the disc mount adapter or the center-hub clamping adapter, you can cut that hole in the sproket a number of ways, most directly with a Lenox 2-1/4" hole saw and arbor (about $25.) Or you can put that toward your new bandsaw, or plasma cutter.

Built well. Too big for my application. I used the disc mount bolts, everything lined up but sprocket rubbed on frame. I used a 32t and it’s still close but it works.

This sprocket was super easy to install, I used the 6 bolts for the disc brake to bolt it on to my wheel and it's holding up just fine. I gained alot of low end torque using this sprocket, and surprisingly I didn't lose a whole lot of top end speed , I went from 44 to 56 tooth, my top speed went from 60 to 55 km/h , but well worth it, before I felt like I needed to pedal to really get going , but this thing just wants to go now . Thanks guys super happy so far.

This thing is very good quality. Its the thickness of the inner link if the 415 chain. I regret not buying these sooner. Much more better than stock sprockets.

The center holes, the 6 used for a disc brake mount, have incredibly thin walls on the edge between them and the main center hole. The three holes, used for hub adapter mounting, were ever so slightly off from fitting a cdh hub adapter. To fix this i drilled the three holes out, until i could fit all three screws in. It also appears that the sthus hub adapter would line up with this sprocket, but i haven’t properly tested it. It does fit a 415 chain, just make sure you have some extra in case you end up 5 links short like i was. Torque increase makes my bike feel way better to drive despite the pocket bike transmission
