Steve, These 175's are a sturdy, well balanced machine and have a particularly snappy powerband when compared to the other Enduro series Yamahas. I think they were one of their most efficient platforms in this series. Faster than the 125's and lighter/quicker than the 250. I rebuilt this Kawasaki F7 with a new complete crankshaft assy and a .040 over Wiseco piston set, cleaned up the porting and re-jetted the carb. For an F7, it ran very well. This stock Yamaha would give it a good spanking. Mark.
