I have some Oxford muffs. On the move the wind pushes them against the clutch and brake levers. I would only use them when I have handguards fitted. I used them on my "Vee" like that and with heated grips inside they were toasty warm. Heated grips are good for warm palms but the fingers get nothing when exposed to the air stream. I have mostly rid myself of the problem by staying off bikes when it gets down below 10 degrees. I have a heated jacket and gloves and the SV has heated grips, but I am old and my default chilly ride is "car".
