Both the 1090R and 1190R benefit from some setup. While the 1090 is more dirt orientated out of the box, it can be further refined while keeping the 220mm travel front and rear. Its quality over quantity, the bikes are tall enough, we scruitinise every mm of travel on the dyno and it works!
The KTM 1190 Adventure got a name early on for the rear guard being broken by the tyre. The KTM fix was a revision kit, R15019-00, with a stiffer 180N spring and a longer bumper. This made some people happy but not all. Rider feedback was a soft feel, especially in the rear while some riders called it harsh.
Well, they are both right. We think it's largely under damped, which is causing the soft feel as well as the harshness.
We have been working with 1190 and 1090 for a few years, testing the suspension with Chris Birch and checking lots of settings on the dyno. We've honed in on the weak points and we now offer a complete answer for the 1090/1190R, front and rear. This is comparable in performance to the Touratech rear shock and fork cartridge kit, but significantly cheaper.
We do not change the stock fork springs and shock springs for most applications - the stock 5.6N fork springs and 180N shock spring are suitable for a 80-100Kg rider. The stock suspension is under damped in our opinion, and it's this that's causing the problems, not the springs. Every fork and shock is tested on our suspension dyno to ensure it meets our standards. We don't do guesses around here, everything is measured to make sure it is working the way it should.
