I purchased the Pro Grip Gel grips
(two pair so I had two skinnies). Cost me less than $20 and 20 minutes of time. Have the OEM guards.
My stock grips came off easily. I put the heated grips on high until they were toasty and pliable. Then, at the inside end of the grip made a slit with a knife and peeled them back.
Great improvement. Vibe free too!
