Featured Replies

Does anyone know what is the size of a standard rear sprocket on a 2007 Beta 270??

Also how can you tell the difference between a quick action and slow action Donino throttle, I am sure one has a white body and one is balck but which way round is it.

Thanks mon amigos

    Hi there, I think beta standard rear is 41, same as 4rt. I use 43 on my 4rt to calm it down. The black domino throttle is the slow and white the fast. The throttles make a big difference to how the bike performs. Clarkey
