It looks like the DRZ is different then and will not fit.
Looking to try and get a Rekluse but trying to find one that fits is difficult.
There was a thread on here where someone fitted a complete Rekluse clutch to his 515 FSE
http://www.gasgasrider.org/forum/sho...ghlight=clutch
where he stated he had seen one on a older 450 and it did fit his, but I can't seem to find a part number or other information on the internet.
Has anyone seen this fitment. Really need to try and get the clutch sorted soon
