Huge variation in models: ETS Trophy Sports had unique styling; TS250 Sport handles and goes well; Supa Five had redesigned motor and nice styling; ETZ has the best combination of qualities. Drum brakes not really adequate (use rear brake arm at the front) and many early bikes went through mains as quickly as Honda V-4’s went through cams. Regulators are a weak spot in the electrics and gearbox bearings can go at any time. One of the few Iron Curtain bikes to offer a decent riding experience.
