Re: 954 fork preload question

I tried setting the sag for a 160lb rider. The best I could get was 2in sag

Agreed - The stock suspension is complete junk. Dan Kyle is the man to talk to about having it re-sprung for ANY weight.

With your weight (or any weight really) you'll never get close to the correct sag with stock springs...sorry but the stock stuff is some of the worse suspension out there.....way too undersprung...junk! Send'em to DK for work.

Re: 954 fork preload question

It is the total sag from the fully extended position, Its less than ideal but you can always pull the bike on to the side stand until the wheel comes off the ground and have an assistant measure it

Ps. at 80kg the standard 954 front springs are too soft for all but touring! I would recomend 0.90kg/mm or 0.95kg/mm for your weight!
Are you saying I'm fat?

Thanks for the advice. As it happens, my wife will be riding this bike when we go riding together and as she weighs less than me (I'm not saying how much exactly as she may 'spy on me' and read this) I'll probably set it up a bit soft anyway.

Is the sag you recommend over and above the static sag of the bike's own weight? Or do I have to lift the bike up to measure from the fully extended fork position? (that would prove a little problematic me thinks).

Re: 954 fork preload question

From memory I think its about 14 turns (+/- 1?) you should adjust it so that you have about 30-38mm of sag with you sitting in the riding position with all your gear on. Closer to 30mm for the race track and and more towards 35 for the road although your riding style and individual preference also factor in. Also make sure the rear is set properly 28-35mm, again the smaller number for the track. If you add a reasonalble amount of preload you may then need to add some more rebound damping!

Ps. at 80kg the standard 954 front springs are too soft for all but touring! I would recomend 0.90kg/mm or 0.95kg/mm for your weight!
