I put my ATV muffs on my 09 wee yesterday , for a group ride in temps @ 2 deg c .
I had purchased them years ago from Royal Distributing for 20 bucks , out of desperation while on a cold ride on my drz400 . I too hate the frozen fingertip syndrome .
I melted the same hole for the mirror stem as another posted , but have yet to find something to seal it ( curtain grommets - brilliant )
Pro's - hands were warm throughout the ride , had to turn the grip heaters down to 40 % , wore light gloves . An occasional whiff of cold would enter the mitt , but other times a wave of warmth would wash up my wrist and forearm .
Con's - awkward to walk the bike around the garage since one can't just grab the handlebar and push /pull , difficulty in activating signals and switches , as they are in the tight " neck " of the mitt - everytime I inserted my left hand into the mitt , the horn would beep . Turn signals took a real effort to activate and cancel . On one occasion the cord from my right grip heater contacted the kill switch , causing the motor to die inexplicably in traffic . Since that area is invisible , and inaccessible without removing the mitt , which would require removing the mirror , it took a few moments to figure out .
I'm going to keep them on the bike and ride again today !
