It's great you guys all say fit a spacer, but I've not seen anything mentioned about setting the sag after this was done?
I only fitted a 2.5mm spacer, just to try and I must say - It did make the bird better on the track, slightly quicker turning feeling.
But doing 260 KPH - GPS speed on a right sweeper had my arse wobbling all over.
That's no fun at all. Had to fight the bike and drop a knee to try and keep it on the road. Only afterwards did I start looking into static and loaded sag, and found that this was completely off.
So basically, don't just think that by putting in a 6mm spacer that everything is now going to be better - it ain't! Check the front and rear sag, and set it up according to the info provided.
I'm still not 100% happy with mine, still fiddling with the suspension, and have dropped the spacer out to try and get my confidence back after that scare.
