Once popular single that seems to have disappeared from the road – probably down to top end (especially rocker arm) problems after 40k. Quite a few were quickly destroyed by DR’s, infuriated by the way it could stall at low revs, especially after the electric start burnt out. Rather elemental for some tastes. Also, front discs go thin and calipers rot. Bits, even engines, from the GB500 will fit (or vice-versa). Look for smoothness in used examples, as bad ones do vibrate harshly.
