I found these for a decent price, but I'm wondering if these will be good to go for my M2L.
I'm at a little over 10,000 miles and am wondering if it'd be good to replace the stock springs with these because I found them at a darn good price.

Also, what's the benefit to a higher spring rate?

Riding style:
I love twisties when I can find them, and ride 'em hard.
I ride with a passenger about 40% of the time.
I pull wheelies...A lot. Bring 'em down as soft as I can though. =)

Based on the experience with my 00 M2 (not a Low), if you weigh over 160lbs 'wet', the stock spring rate is too low. You have to crank the pre-load all the way down to get the bike at the high end of the sag spec.

You might have to shorten the spring spacer to fit a Low fork. I'd call Traxxion Dynamics to be sure.

Well Dj, considering I weigh 200, I guess that explains why it's cranked down eh?

LOL

I'm probably close to 190 suited up, not too far behind you. Not sure what the stock M2 spring rate is. I made some longer spring spacers (5/8" longer) and got the sag right, but the stock spring rate doesn't seem to match the stock damping very well. It really does need the stiffer springs. I'm going to try to make my stock springs stiffer by cutting them shorter and increasing the spring spacer length.

It works on paper...

Can you PM with pics when you get it done? or make a write up if it works? I might try it if it works for you!

Gotta love being the guinea pig!!

You erally need to match the spring rate for your weight, and I think the 85kg/mm rating might be a bit soft for a 200 pounder, especially if you ride 2 up a lot. You might try calling racetech, they could recommend the correct spring rate for you. Or go here:http://www.racetech.com/evalving/menu/searchstreet .asp

you might need to call them about your M2 low, I suspect it uses the same spring with just a shorter spacer, but I don't KNOW that for a fact. I am 5 or 10 lbs heavier than you, I believe I put the 1.0kg/mm rate spring in mine( I do some 2-up riding as well) and I am VERY pleased with the results. I used the goldvalve kit as well, but just the right spring will make a HUGE difference.

Hey... thanks for that cool link!

According to Racetech, stock M2 forks have a spring rate of .730 kg/mm and I need a .883 kg/mm rate for my 175lb 'dry weight'.

I should be able to measure the spring length and cut it down proportionately to raise the rate. It should work as long as it doesn't get so short, it coilbinds before the forks bottom.

At least, that's the theory.

Springs really don't cost that much new, I wouldn't mess around with cutting them MYSELF, but that's just me. Besides, it's nice to only have to tear it down and put it back together ONCE.

Of course, that doesn't give you the SATISFACTION of having figured it out and done it all yourself, maybe I'm just getting lazy...

A proper rate spring would be better than messing around with the stockers, that's for sure. I'm not even sure they are long enough to trim... they are pretty short to begin with.

It's just that I already had the extremely difficult to get stainless steel tubing in a metric diameter for the spacers laying around. If I don't use it for this, I can't take advantage of the serendipity.

I've never used the word 'serendipity' in my life, btw... just these two times.

I have a set of new racetech fork springs for an S1 that are for 160-175 lb rider, as well as stock used S1 springs. If anyone wants them PM me with an offer.

Just got a message back from Dan @ Traxxion concerning the spring rate.

Dj, there are some springs on ebay cheap as hell, perfect for your weight I believe. $25 plus shipping, which they are normally $109.95, but Dan said there are way to many of them laying around and they need to get rid of them.

Spring on the is .85kg/mm
