I have the touring version so heated grips came as standard, they didnt work from new, so waited until the first service to get them fixed, after the mechanic said "yes, nice n hot now" I took it for a ride and couldnt feel anything through my gloves so removed my gloves and felt the grips, left one was warm on top, cold underneath, right one was cold on top but luke warm underneath, so back to the dealers and they tell me that suzuki, Honda and Kawasaki all use the same ones and they are only heated half way through and my right one has been put on upside down, and needs a warranty claim for new grips, so I asked for the better Oxford ones, they said yes, free of charge, So I go back in January to have them fitted. At least I know Oxford ones get HOT.
