I've been wondering about the feasability of putting a WR tranny in my yz426f I would prefer to have a wider range..... as in a slower first and faster 5th my top end suffers as well.... I ride everything from trails to wide open desert... so I would like to have the full range.... and with the wide torque band I don't see the need for the close ratio's mine came with.

This has been done a number of times. It makes a good swap.
