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.

There is a thread on this in the suspension forum. I think there are a couple 09 models that use the same springs.

The 2010 has slightly more front suspension travel than previous years. I don't know if this means the springs are different. Any suspension shop should be able to steer you in the right direction. Besides having a bit more travel and most likely different valving I doubt the 2010 fork is much different than 2009.

I can verify wheels7 commnets about MX1 working on this setup. I know the person that is doing their testing. I have been at Hangtown twice while they test. As of a week ago they had made good progress. The test rider has done work for another local business and I have used his results on Hondas. When the time comes to get an '10, I will talk with my friend to assess the final outcome, and am confident that I will like it.
