I've had a few people ask about my throttle grip. I had a problem with hand discomfort, found this fix. I find it adds maybe 100 miles to my comfort range for a sport bike day trip. Pictures ... Solution was $11 Cramp Buster. Originally designer for the cruiser market, but modified easily to fit sport bike ('05 gixxer 1000). two mod's: 1) cut the lever short to allow clearance for the tank during full lock parking lot maneuvers (photo) I've shortened an additional 1/2 inch off the paddle now, compared to photo, and it still works fine... 2) cut much of the circumference of the grip to allow my palm to get to the grip without riding up on the 'Buster', (photo) This way the 'Buster' is not a part of my palm to grip action, but only the paddle. I can cover the brake with 2 fingers, work the throttle and relax my 3rd and 4th fingers all at the same time. and it added 100 miles to the range I could comfortably ride in a day. and these are the tools needed: oh, and I also used a file to smooth the edges after the sawcut I get a more relaxed hand out of it.
