So I'm pretty much set on buying the 2010 YZ450. Problem is, I cannot find any supplier of suspension parts for this model year. I've checked Eibach, Race Tech, even Yamaha and have Googled 'til the cows come home anything suspension related to YZ's. No joy for the '2010 model. I will need to uprate the springs as I am 6'4' and 240 lbs w/o gear. Can anyone help me find a supplier ? Any pointers will be much appreciated.
