Hi guys ,Have just found this thread i wish i had seen it in September as mine broke 30 miles from the hotel we were staying at in southern France about 1000 miles from home ,the recovery company that came did try to fix it then went away quickly when i started it the throttle was on full so i cut it out and ripped of what they had done and fixed it my self ,we took 45 Min's to get back to the hotel .We looked on the net and found a Triumph dealer 2 miles down the road (luckily as there are not many in France)I have nothing but good to say about the people there they looked after us very well ,they did not have a new grip to fit the Rocket but took a new one of a new bike in the showroom possibly a Bonnie ,they fitted it for me gave us coffee in all it took 2 hours .The end result was we carried on with our holiday with no problems.
The cost was about £38 /$50 which to me was amazing i have not bothered to go to the dealer here as the grips are 18 months old .
