Post subject:  XB12s Suspension
Well, I've had my XB12s lightening for a couple of years now and have been on the verge of selling it a few times. My main concern has always been the handling. It's always been unstable over bumps and ripples in the road whilst under acceleration. The suspension and tyre pressures have been set as per the manual but I've never been brave enough to stray too far from the factory recommendations.
So today I was off work and the forecast was reasonable so I had a ride up to Knockhill circuit to speak to ERS who specialise in Ducati suspension mainly to ask a couple of things about my 999s.
Whilst I was talking to Eddie at ERS he spotted the Buell and said he loved them and used to work on them. I mentioned the handling thing and he had a bounce on the bike. Too much static sag give it half a turn on the rear rebound and a touch more front compression. Drop the tyre pressures to 29 front 31 rear.
It's a different bike. Stable and sure footed I can't believe the difference he's made.

So if you are up north I can thoroughly recommend ERS 8-)

aint run recomended tyre pressurs for 3 three years ,i run 31 /33 ,recon there might be a trade of runnig softer as well, WHEEL BEARINGS may last longer :yup: :D :D

Been having the same woes with XB12 SCG. Difference being, I've fiddled with suspension settings a lot to try to sort it and to counteract the harsh ride I was getting, but to no avail. It was tracking in even minor seams in the road and generally just giving no confidence; feeling that it would just slip from under me at every turn.

I thought tyre pressures might be the issue but with all the info recommending sticking to the manufactures setting F 34 / R 36, I only strayed by a psi or two either way, with of course no effect.

Then I got to thinking, I am light; 10 1/2 stone at most, so how is it that I am being told to use the same pressures as someone twice my weight or with two up...? Surely I thought, the tyres must be manufactured to offer the best grip, handling and feedback, with a specific amount or tyre footprint on the road, which for a lighter than average rider like me, could only be achieved by dropping pressures.

So a few days ago I took the buell by the horns (pun intended), and dropped them to F 30 / R 32, and had a similar eureka moment. I feel I am at a much better starting point to now experiment with the odd psi up and down, and after finding this thread, will try the 29/31 recommended by Eddie :worthy: first.

I'm 10 stone wet, use the manual set up and run 34/32, 32/30 on track. Seems to work, but my r probably puts more weight over the front than your scg.
I'm in west Sussex if you fancy a trip up to brands by the way....

Are you saying you are running higher pressure front than rear? .............

It's getting more common these days. Some brands like the new Dunlops let you run very low pressures on the rear, but the front is often higher. Only usually seen on the track though.

No, I was putting the rear tyre pressure first....
