The set up is a CvTech clutch with a different engagement spring . I ran this with stock tires on my 570 and it would catwalk with ease . It pulled 2 to 3 lengths faster in a drag race without losing any top speed . this set up cost 549.00 for the clutch and 30.00 for the spring plus tax . I want 400.00 CAD for it . Has 500 miles on it . Prefer to sell in Canada but might consider shipping to States .

This clutch can be converted to run on my 850 which I am planning on doing if I do not get the 400.00 plus shipping .

This clutch will work on the 650 or 570 . Part number 0900-0034 .

Put bike back to stock before I traded it in and cannot believe how much it lost in performance with the stock clutch down low .

Also have an HMF programmer for a 570 .
