Just trying to facilitate some discussion as always:
Okay these are some "generalizations" so use your own frame of reference to guide you. Which scenario below would you say would result in a more skilled rider?
A) Riding a cruiser say 25,000 miles then going to a sportbike?
B) Riding a sportbike for 25,000 miles then going to a cruiser?
And just for extra credit:
C) Riding a harley for 150 miles and going back to a bike
