Shock Spring Rate

I just figured out the shock spring rate on my bike, it's 131 N/mm. I haven't set the sag yet...

I weigh 190lb, or more like 210lb with gear. I really have no idea if that spring is too stiff for me. If so I'll have the shop swap it out. Is there a guide or something somewhere that maps weight to shock spring rate?

Thanks...

UPDATE: Found this out:

Stock = 12.6 kg/mm
Mine = 13.36 kg/mm

Set your sag. Aim for about 35-40mm for the Street. If you can get that without the adjuster being near one end or the other of the shock then the spring is in your range. If you need help setting sag go past a local bike shop and have them help you.

Plug in your bike and weight with gear, and it'll spit out an answer. The stock shock on most bikes is sprung about right for a Japanese teenager.

Also, come down to the track on an OMRRA weekend. Barry from KFG can help you out with setup (between race bikes)

Hmm, I never heard of CCCP helmets... Seriously the actual link would be really helpful. Are you trying to send me the RaceTech link? :

RT - Digital Product Search

It tells me to put in a weaker spring than stock! I'm curious to see what your calculator says.

Recommended Spring Rate: 11.6 kg/mm (use closest available)
Stock Spring Rate: 12.6 kg/mm (stock)


Yeah it's true in street as well as dirt, they are sprung very light stock, which is why I'm skeptical of the calculator above.

As far as setting the sag goes...

If I want to set it for track? I'm doing a track day on July 20th (novice group).

Also, what do you recommend for the static/resting sag? The number I've seen in another forum is somewhere in the range of 5-13mm.

Thanks...

Doh. Yeah, I meant to paste in a link to the Racetech calculator. Instead, you got Valentina Tereshkova, the first woman in space. And I can't precisely remember why I had a link to her picture in the clipboard. Just think of it as an awesome surprise =).
