£35 from Busters. They're German grips with a 3 position temperature control. The Suzuki throttle barrel has moulded in bits that need removing with a scalpel. I cut out all but the last circular bit at the controls end and left the longitudinal ridges. The grips have a moulded end so you have to lose the handlebar end weights. Getting the throttle side on was fairly easy. The other grip was a pain and required liberal quantities of WD40 to get it down over the handlebar end.
