Strong, compact, lightweight, permanent magnet gear reduction starter for pre-Verto flywheels. Replaces the clunky inertia starter. Features internal solenoid, and has a thicker mounting flange that avoids a weak point in other gear reduction starters. Weighs just over five pounds; clears most oil coolers without modification. Can be clocked in different positions if required. Each unit includes dyno output and load sheet.
