Hello. I'm considering changing my fork springs from the stock .90 KG to .95 KG as recommended by RaceTech. According to their website and per my rider set-up, this Daytona (non R) has too soft fork springs (and too stiff shock spring but thats another story) for my weight. To corroborate that I did check my sag (last year, not lately) and my bike does have excessive sag. I don't have the numbers handy but if asked I could find and provide them. Also I've noticed that I pretty much do blow through the suspension travel but have not yet bottomed out. But thats the point- to change the springs before I bottom out. The track I ride is rough and I’m very nervous of bottoming and loosing the front end.

So the advise I'm seeking is- If you know your using nearly all your suspension travel but not yet bottoming, and its measured and said that the bike does come with a extra soft fork spring from the factory, would you go ahead and change the springs now or wait til you start to tick the bottom of them? I know its advised that we’re supposed to use nearly all the suspension travel and thats normal. But I feel I’m dangerously close to the end of it and my pace is gaining steadily. I made alot of improvements the 2nd half of last year. It’s so cheap and easy to change springs I cannot see why I wouldn’t? (I have to do oil this year anyway)

Advise or suggestion? Thanks!

I'm 165lbs and was bottoming my forks out and put in .95 springs. Definitely do it. And the rear spring as well.

Great, thanks!

I was not planing to do the rear because I was nervous about changing the geometry too much especially in this manner. If I stiffen the fork springs AND soften the shock spring it seems to me I would be transferring weight off the front and on the back. Possibly significantly. I lost the front tire on a bike a few years back from similar reasons (and incorrect tires) and am pretty nervous about making significant geometry changes. That and I figured I’d grow into the shock spring? Am I off base?

The front spring is for someone that's 150lbs, the rear is for 230lbs. Unless you ride with passengers often, soften the rear.

No passengers, just track days. It seems crazy they’d spring it like that from the factory. Dunno what they’re thinking…

Thanks for your input.
