Been using these for a couple of years on my 23 GW, love them. I recently got an 08 Honda ST 1300 and decided to add these grips to it. First I installed a set of Oxford Touring heated grips on the ST and installed these over the Oxford with small modifications. Cut a slot on the bottom cover to fit over the wire on the grip. They work great and the heat comes thru even in the lowest setting. I'm sure with a little enginuity they can be used on many other bikes as well. If you have these grips and don't have the palm rests you're missing out big time, I put them on both the left and the right. Thank you Goldstrike for a great product.
