How to Disconnect the Battery on a Triumph Motorcycle

Before starting work, make sure that the motorcycle is stabilized and adequately supported. You don't want your bike falling and causing injury to you or to the bike.

If the engine has been running, the exhaust components may be hot to the touch. To avoid injury, always allow the bike to cool down prior to any work you plan to do.

Before you begin, remove the seat.
