Great grip heaters that install inside the handlebar below the grip which means you can change grips (if necessary) with out destroying the heating element during grip removal. Works with any grips but must install grips after installing the Heat Demon Grip Warmer kit. I have Kuryakyn Iso Grips and only down side with grips that thick is it takes a little longer to reach temperature. Easy installation with non obtrusive control module on clutch lever clamp.


Work great.


These things work amazing. I have them on two bikes now. Four heat settings, low profile button, and you can use them with any grips. The installation is pretty straight forward and all the connectors are included. Just exercise patience when routing the wires and clamping everything down, or you will wind up with a broken wire. Make sure you debur the hole in the handlebars really well too.


buy these.
