bandit99 Posted October 18, 2005 What weight fork oil does the 05 WR450 use? The manual and dealer says Yamaha S1. Does that mean 1 weight? The dealer wants $25 a bottle for this stuff and I was thinking of saving a few bucks by buying a different brand. How much do I put in each fork tube?

clark4131 Posted October 18, 2005 They forks take 5 weight oil. Read your manual as it gives a rather easy to follow process with all the necessary fluid heights, etc...SC Share this post Link to post Share on other sites
