My throttle side heated grip started to disintegrate on my 2008 C14. then the left side wiring broke off. So I order 2 new grips.the only place that had the old style heated grips is in the UK. The throttle side came off easy. almost crumbling in my hand. but the clutch side was difficult. the other fun part is getting them back on. i watched a couple of U tube vid's and it went without a hitch. I purchased the grips at an online store called the visorshop.com.
