Adige makes one too. As far as I know, the '08+ 450/510 takes the same slipper as the 610 did/does so you should have lots of choices now.
Thanks for the links! Now I have to find one for a 2008 SM610 - seems a lot products for 610's up to 2007 though.
slipper/anti hop is night and day for fast fast asphalt riding. makes stalling easier in the dirt and has a funny feel. ive been told that the 510/450 is NOT the same as the 610. Ive only heard of ONE case where the guy found a slipper that fit a 610, its was a fast by faracci sp?
