A typical grass outfit originally built and raced by Dick Craven from York used a 650-Triumph engine, Norton gearbox running on Methanol,"dope". replaced triumph eng ,with a 998cc VINCENT engine for more power
Their owners built most of the outfits in the 60's but this started to change and by the 70's experts professionally built lots of machines.
998cc NORVIN , vincent eng in norton featherbed frame . got to be THE ULTIMATE CAFE RACER.
