I installed some of the $29 heated grips on my other Aprilia. They were just the elements that wrap around the bar, under your grips. I felt they were great on cool days, but I also found that the more insulated my winter gloves were, the less I felt the heat. Wearing my summer gloves allowed me to feel the heat, but my fingers still froze. Around that time though, I was trying to find some decent gloves, and was going through at least a pair a month. I'm not at all opposed to putting them on my current ride, but I will admit, I HATE installing them.
