Been giving this some thought today and weighing up some options.
Before i go out and get a box i've been reading bit from earlier in the thread of Trickys and G.Ps thoughts on the bike regarding 'fork dive' and while i don't recall having an issue myself, i've never been known for 'feel' on a motorbike, certainly not in the same way i have with a MTB that's for sure.
There's a number of options.
1. Fork oil, replace some/all with heavier weight oil
2. Springs + oil
3. Ktech SSK piston kit.
So i had a chat with Colin at 100% suspension. I've known him for many many years and he knows his stuff.
.the honest answer is the weakness of most forks is the damping which is what the piston kit cures if we take this as a complete package ie springs and piston kit and we say that overall that feels 100% better the springs are about 20-25% of that, the rest is down to the improvement in the damping
So i'm pretty sure i know where i'm heading with this, but if anyone in an XSR/MT09 or even just knowledge of the world of suspension has thoughts, i'm all ears
