Have to admit, not very impressed with the heated grips on the mk3 I've used an IR temp gauge and it showing that both grips are sitting at 34*C at idle at the top setting, should they be warmer than this or is this normal I've never had them on previous bikes so not sure what to expect.!!
Doesn't sound very hot to me. Its rare to have them on the max setting because they get too hot, suggest you get the dealer to check them.
