YOXUFA 40/41/420 Chain 48T Sprocket + Go Kart Sprocket Hub with 1" Bore 1/4" Keyway Replacement for Go Kart Cart Predator 212cc 196cc 6.5hp Engine Heavy Duty Steel Silver Powersports Accessories Parts

Note that the four nuts and bolts included are to small to properly attach hub to sprocket.

I bought this for my daughter's go kart build. Have it geared 60:1 ratio so she can do off road on it without too much clutch slippage. Works great!

Great quality. Just as expected and shipping was fast.

Good quality, seems like it should last. Only issue was there were x4 8mm bolts included and the holes in the sprocket & hub are 10mm. Scrounged some bolts and nuts from my bolt bin and all is good.

Did a great job

The sprocket was as described. The only issue is with the mounted hub's 1/4" key groove and key. It was to spec for its own key, but the key was too small for the shaft it would have been fit on. I bought other keys that fit the shaft perfectly but was too large for the hub. A little filing, or machining would fix the issue, but I don't have the means to machine, and want a better quality key slot that I can't get with simple filing.

I dont write reviews, I had to on this one. The center hole of the sprocket doesn’t go over the “hub”, you must bolt the sprocket to the side of the hub. The bolts provided are way too small for the sprocket and hub. I drilled them out to 3/8” so it run somewhat true. Then the sprocket was about 3/8” wobbly. I put a dial indicator on it, got a great big hammer and proceeded to straighten it so it wouldn’t throw the chain off. So get your drill and dial indicator out before you place your order.

No issues so far about hr of use as of now
