Highwayman HPI ignition systems for the Honda CB160 CB/CL175 CB200 based road racers
Highwayman Bikes is now a official dealer for HPI ignition components.
Also ask about systems for the Yamaha YCS1, Yamaha CT1, Kawasaki F7 Kawasaki F9, and others too!
I offer a high quality, bolt on, low inertia, magneto-CDI racing ignition for the small Honda twin GP200 class road racers! After spending a few years racing GP200 with AHRMA it became apparent that ignition failure was a leading cause of Honda riders missing races. Having had much success adapting HPI ignition components to run on my two stroke racers decided to share the wealth and make a reliable, race-quality, easy starting, high revving system for the Honda twins that wouldn’t miss a beat.
