[QUOTE="MikeS, post: 191299, member: 18813"] Marcus not sure if theory or fact... This is the review from Rt opinion on riding the 02 KTM: [B]The stock 2002 KTM 250 is the leader of the bad suspension group. The front end is harsh throughout and even harsher on "slap down" landings. The bike developed headshake when accelerating and the rear-end deflected and skated around when hitting the small, square-edge bumps. The problems escalated much worse with speed. Test riders didn't feel that the suspension bottomed-out, indicating the harshness is felt through the entire travel-curve. This condition made the KTM display very inconsistent behavior when riding on the track, as the bike did not respond the same from obstacle to obstacle. The rear shock spring needs to be much more progressive contrary to the popular aftermarket "straight rate theory" (see rear wheel force curves). The KTM's leverage ratio curve is the flattest of the 2002 models, indicating that the action has very little progression. Unfortunately for the bike, the firm seat takes away from the ride, particularly in corners and turns, where the hard seat makes the suspension feel even harsher than it really is.[/B] RT has developed A "NEW" Spring that has a better progressive feel in lieu of different valving to solve problems....I think Jer has pointed to this progressive spring theory before as being tough to work with since true control of crossover is difficult, unlike Works Performance approach with a properly designed shock body and pre load system for dual and triple rate progression. I would like to read Jer's comments on these graphs and more on the workings of the PDS. Thanks Guys [/QUOTE]
