Sorry, gotta disagree with this statement. Sure they may know the bike more intimately but... most everybody thinks their bike is the best, blind to the reality of it's short comings.
I'm a long time member of the ZRXOA board. Guys swear it's THE best all around bike ever. I once questioned why, if that's the case, does almost everybody change almost everything about the bike I got ripped a new one. From exhausts, carburation, wheels, suspension, turn signals, seats... you name it, they change it. I don't think there is a perfectly stock one on the planet.
