Most noteable difference other than superfical cosemetic's are the following:
P250 wheelbase =59.6 "
S250 wheelbase-56.2 "
P250 = single front disc brake
S250 + dual disc brakes
P250 = dual interconnected gas tanks
S250 =single..
The wheelbase differences have + and - for both models
P250 longer wheelbase= less twitchy at higher speeds,more foot/leg/knee room and more under seat storage
S250 shorter whellbase= Crisper handling at low speed and a stiffer frame resulting a more aggressive handling attitude
P250 single front disc brakes= more than ample
S250 Dual front disc brakes = sport bike like
P250 dual gas tanks=allows more foot room via FLAT floor..Size 14 feet
: Funky gas gauge
S250 single gas tank ,better gas gauge and will accomodate a fuel injection system on future models
2007 P250 = 39000km ...its just keeps on going ,going ...............
