Thousands of  vehicles have experienced the benefits of upgrading their standard ignition system to an Electronic POWERDRIVER or BLACKTOP  Ignition system. BLACKTOP models are Positive Earth and are available in six and twelve volt versions. POWERDRIVER comes in Negative Earth versions, in six and twelve volt varieties. Our Dual Channel POWERDRIVER variants have two systems in one, and can operate twin coil and points systems seen on many motorcycles, and also come in six and twelve volt Negative Earth. Powerdriver units are VERY compact ideal for tight spaces found on motorcycles.
