I weigh around 200lbs with gear and it seems like my suspension is to soft. Who makes heavier weight springs for these bikes? Are they reasonably priced or should I get some measurements and just find a heavier one that will fit?
On the 08 SM 610 the k of the rear spring is 6,4 kg/mm: the same of the SM 570R, which is 20 or 30 kg lighter. According to the manual, its free lenght should be 245 mm +/- 1,5 mm: that's the useful limit. I don't know its width, but it's easy to measure. So, if you don't find a speciific stiffer spring, you should look for a spring of the same dimensions, with a k higher than 6,4 kg/mm.
http://www.promotionsuspension.com/ did the work on my TC450 and I love it. Many folks here use and swear by http://www.watsonperformance.com I reckon you could give either of them a call. I don't know why my text is changing colors or randomly bolding.
