it could fit but id email bad ass first to double check that it does on the bike you want.
not sure id want a bike with the magnet on the disc rotor as will be limited to just those rotors and prob expensive too but i have never seen one so could be wrong on that.
Thanks guys looping the sensor back worked a treat,a bit of advise tho you need to fit a bracket to put the sensor on so it's a few inch closer to the magnet otherwise it won't work
