Description
Our ‘Pro’ kit gives air cooled engines a power boost at the flick of a switch.
Rex’s Dual Power™ electronic ignition has a worldwide reputation for performance. With two source coils providing power, the sparks are hotter and more stable than systems that only use a single source coil on the stator. The result is smooth, predictable power delivery with no peakiness, a combination developed for specifically for trials riding.
The “Pro” version has two timing curves, one developed to be smooth from walking speed to full throttle, plus a second switchable curve for a useful boost in power. The 175 motor performs extremely well with additional ignition advance giving a useable power increase.
