Ive got a 2012 Roadster and the ABS light has appeared suddenly for know apparent reason, Ive checked around the bike as for dirt and clearance on the sensor but found that front cable where its close to the head stock has been squashed, apparently a common issue I have since found out. My son who's a mechanic is going to check the cable out with a multi meter but what values ! volts-or resistance should he be looking for when he's testing !.
