grips... the foam slide on type are great & quick to put on

hyea::clap: just use a liberal amount of hand sanitizer on end caps & is side the grip, they will slide right onnojoke the the sanitizer evaporates in a short time drying it to the stock grips. No slippage on throttle ( I am with Bfromla , on this one , never had the hand warmers on with the foam grips so I can not tell you what to expect there , but those grips are great for longer rides ...)
