When I had my 06 450 I had a upper clamp by TAG Metals (Revolution clamp) Now I just have the upper clamp and I took it off of my 06 and stored it away. I was wondering if it would fit on my 2010 450? Is the Diameter of the outside of the fork tubes on the 2010 the same size as the 06? I have been getting my 2010 ready for the first race next weekend and will be putting on front brakes tomorrow and a new front tire. While I have the front tire off I thought I would try and see if the upper clamp would work. Just by looking at the clamp I dont see any reason why it shouldnt but thought I would ask before I removed the stock clamp thats on it now. I would rather have the Bridge style handlebar mounts thats on the TAG clamps than the singal individual type thats on the stock clamps. The TAG clamps also have the rubber cushions on the top and bottom of the bar risers.
