Thread: Need to find a 428 Rear Sprocket!!

I'm hoping some one can point me in the right direction.

I have a 1970 Honda Trail70 with a replacement Lifan 138cc motor and the front drive sprocket is made to fit a 428 chain.
I haven't been able to locate a 428 rear sprocket that will work with my bike set up.

Any and all hep is much appreciated!

Best Regards.

It might be easier to get a 420 countershaft sprocket than to find a 428 rear sprocket. The 420 and 428 chain have the same pitch, but the roller diameter is different, 0.306" for 420 and 0.335" for 428, so mix and match is a bad idea.

Just a thought.

Kevin Is right. Front sprocket is way to go. I think Beatrice sells them for chinnise motors in 420 pitch. hope this helps Grant
