get it set up for SM use for a 13stone chap, then it'll be PERFECT for all uses, thats how my WR was and inspite of being shortened, it bottomed out LESS offroad than on the stock sussies !
So that's one vote for each so far then.
Fat* lot of fucking use you cunts are.

I've never ridden a bike that was properly setup for SM, but the stock suspension on my XR (which a mate set the race sag correctly for me) was nice and plush on the roads and trails - but I never jumped it due to the risk of causing an earthquake.
The stock (as far as I know) suspension on my WR was lovely and plush, but a bit soft.
My mate's YZ426 was fookin amazing - he's set it up for himself, unsurprisingly enough, and I think he only weighs about 11 or 12 stone. He finds it way too hard for MX and gets bounced out of the seat all the time, but I thought it was great.
My KTM on the other hand isn't very plush over small bumps, and is hopelessly soft for big jumps. Which seems quite an achievement.

What's the advantage of getting it shortened? The thing's tiny enough as it is, so I don't have any trouble reaching the ground.... but if it sits much lower, then I'll be forever catching pegs and boots when riding in ruts... does it improve the SM handling that much?
