I have the Kuryakyn ISO grips with the throttle Boss fitted.(basically a wedge that sticks out from the twistgrip and sits under your palm.,making it easier to hold,twist and blip the throttle.It's also adjustable)
These are great.Nice comfort and good grip for your hands.Isolates the vibration and the bigger diameter is kinder to your hands.Less 'Monkey Claw' hand cramp.
Well worth fitting.
They are on my list to check out. On another note, has anyone installed the switchblade pegs? I am seriously considering them
Switchblade Pegs | Küryakyn
They came on my bike when I bought it (used). I never open them, as they don't really do anything for me. I can't put my heel in the detent on the swing part, as you'd need a size 5 boot to be able to do that. They also don't look that sturdy. Closed, the pegs are fine, but I wouldn't pay a dime more for the opening part.
Now, after all that, if you still really want a set, PM me and I'll make you a good deal on mine.
