Tuned 88 with twin carbs and siamesed exhausts, with neater line in styling. A reasonable combination of power, economy and reliability whilst still having some blood and guts even on modern roads. 80mph cruising’s possible without too much vibration on a well sorted motor. One of the nicest Norton twins, especially with an upgraded top end, and can annoy middleweight Jap’s in the corners! Some really nice bikes out there.
