The spring on the back seems quite soft, the bike drops more than I thought it would when I sit on it. Has anybody opted for a harder spring? Could mine be just shagged?

More questions probably on the way!!!

Cheers!

Oh Yeah! Most of the TT members have changed the rear spring to suit their sag requirements. Try a suspension specialist in England to advise on spring rates. 5.6 KG rear for 210 lbs or 5.8 Kg for 240 lbs. is the direction you may need to go.:cry:

I went to a 5.6 and it was like a new bike. I'm 215 lbs.

So, can anybody in the U.K recommend where I can get a harder spring from such as 5.6kg?

When replacing the rear spring, go Titamium to save a lot of weight. Call John at Renton Coil Spring: 714.401.5572 Calif. A titamium spring actually reacts quicker than spring steel, an added benefit.

I'm not sure, but isn't the stock spring already made of titanium? I'm pretty sure I read that somewhere. Unless the rider is over 200 lbs., the stocker should be fine, assuming it's properly setup. Most riders never even adjust their preload/race sag or comp/rebound dampening. I'd try a handful of different settings before spending money on expensive springs or revalving.

I used Racetech's website to calculate the rear spring rate based on my weight abilty etc. The spring dimensions are on the website also. Then I bought the spring from k-tech in Coalvile Leicestershire. They are very helpfull. :cry:

I'm a light rider (160) but man that spring seems really soft. I've had wound up a little, which when on the stand looks better, when I sit on it, it really does drop. It then looks like a DT125!

No, the stock spring is NOT Ti. No manufacturer uses Ti springs, but all the pros do. I have a Ti spring from Renton Coil Spring as well, and it was two pounds lighter than the stocker. Next time you hit the Supercross, look for the RCS logo on the bikes. I know you will find it on ten out of the top fifteen.
