Basic thumper, still made in Japan where it’s equipped with a drum front brake! Also Jap 27hp 400cc version with less vibration. Old UK models used to destroy the piston, camchain and gearbox; vibrate strongly above 70mph and had endemic electrical rot (including the killswitch shorting out) that made kickstarting near impossible. Newish imports at £1500.
