Hi all,
New to the forum but been reading for a while and impressed with the knowledge out there.
So having studies the forum for a while, I've made several mods so far - jack-up kit, braided lines, Ivans soon.... Was going to do an R6 shock upgrade but read about the BMW S1000RR conversion and one was on ebay for £80, so bought that.
All fitted OK after drilling washers etc., but what I was surprised about was that I couldn't get the appropriate sag...too saggy even with the preload wound right up. I measured 20-25mm of unladen sag with that increasing to about 45mm with me sitting on it. Not good. That's with the STD dog bones as I like it a bit higher. I took off the shorter dog bones as it was so high with the BMW shock that the rear wheel touched the ground with the centrestand down!
What's confusing me is that on this and other forums the BMW spring is supposed to be firmer than the Yamaha one, but I managed to get the STD shock to the right pre-load no bother. So that would indicate that the BMW spring is actually softer??
Took it for a spin and it felt so much better than STD, especially the damping. Any thoughts appreciated. Thinking of getting an uprated (BMW) spring from Ktech for £85 fitted.
I'm around 14stone in all my gear.
