Drive Coupler - Yamaha 18mm

This billet drive coupler is the same length as our Yamaha driveshaft coupler, but with 18-1.5mm threads.  The threads are machined approximately 22.5mm deep into the nose of the coupler.  The nose of the coupler sticks out 1.22" and the overall length of the coupler is 2.37".  This uses the Kawasaki 650-800 rubber damper.
