What is the stock rear spring rate for the 2008 YZ450? Racetech shows it as a 4.9kg/mm, but that seems light. Normally it's around 5.5.

I think the 07 came stock with a 5.5 rear and the 08 is stiffer due to the new linkage. Race Tech may not have the correct 08 stuff up yet. I do not have that info in front of me but I am sure it will be closer to a 5.9 than 4.9, maybe they had a typo.

Thanks! I didn't think they'd go that much lighter
