Call Richard at House of Horsepower. He is a suspesnion dude that works within Cannon Racecraft that makes and sells moto and most other springs to everyone. He will know and also have PILES of springs of any weight for anything. http://www.houseofhorsepower.com/
My 07 TE Sachs would fit up with a Racetech spring for a KLX300, except of course that the stock spring rate for a KLX300 is 5.8 and way too heavy for the TE. It was too heavy for me on the KLX as well. But that series will fit the Sachs and there is a wide range of spring rates.
so will this fit? http://cgi.ebay.com/ebaymotors/PRO-...4454674QQptZMotorcyclesQ5fPartsQ5fAccessories
