  • Polisport Clutch Cover Protection

    Polisport Clutch Cover Protection

    Jeffrey in VA

    So far so good...

    Ridden a couple times with this on and it does the trick. I'm hard on my clutch cover so this should help from all the wear I'd typically put on. Takes only a couple minutes to mount and fits really well. The only thing I've noticed as a possible side effect is it hides a bit of the brake lever tip. I'll either adapt or get a larger tip at some point.
