Captain Carling Posted July 31, 2009 Share Posted July 31, 2009 Im 15 stoneish +leathers n lid and ive got the standard spring on the back of my R1 which ive read is 8.0kg/mm. What spring rate is more suitable for my weight as im thinking of getting it sorted Thanks Link to comment Share on other sites More sharing options...
Captain Carling Posted August 2, 2009 Author Share Posted August 2, 2009 Ive been on racetech website and they have a spring rate calculator so ive found that i need a 9.0kg/mm spring. Dont suppose anyone on here has one for sale Link to comment Share on other sites More sharing options...
wild foamy Posted August 2, 2009 Share Posted August 2, 2009 sounds like a specialist part tbh, or maybe you could try fitting the spring of similar length from a heavier race bike? Link to comment Share on other sites More sharing options...
Captain Carling Posted August 4, 2009 Author Share Posted August 4, 2009 Got me a spring from K-Tech. The bike feels much better now Link to comment Share on other sites More sharing options...
