John Player Special version inspired by the unlikely success of the Nortons on the race track had a usefully protective twin headlamp fairing but uncomfortable riding position. Make sure you buy the 850 version, not the race-track 750 model. Excellent pose tool but easy high speed cruising meant many motors ended up thrashed to death. Nice bit of British history to summon evocative memories.
