To add my 'two pennies worth' of wisdom......
I have a GSXR400 that maybe has something approaching 60 bhp and to ride that properly and make good progress always makes me smile like a b*stard !! I love keeping the motor in the fun zone and just slinging it in to corners. Proper , proper fun. All I'm trying to say is that you don't always need big horse power to get the grin factor.
