I am sure a lot of you guys know this already but after hours of research thought I would share. The handle bars on ca77 and c72 use Japanese
7/8 handle bars.when ordering new grips order a set for the 7/8 size BUT the throttle size hole which is bigger (!.000) WONT WORK. The Throttle side is 1.125 or 1inch and one-eighth.so solution is by a set for 1.ooo inch Harley they are 1.125 for the throttle side.yes it seems wasteful to use 1 grip out of each set. But if you want original they will cost you at least $50.00 thats out of Thailand.I didn't want to wait 2 months.you can pick up the GT style for 10.00 a set on Ebay. hope was helpful, Choctaw
