Fits 1049 Yamaha four stroke 2014 – 2017 and should work on any 30 MM crank engine. You are responsible for fitment. Clutch has seen very little use. Less than 500 miles in testing from Cat engineering. Bought from Cat as spare and never used it. This is the 8” Team clutch for 30 MM taper crank with no slop in buttons and rollers. Uncalibrated, but has a spring in it. These are $600 plus new. $350.
