Old style twin, not developed since the 70’s. Runs well to around 50k when either the crank bearings or top end play up but there are a reasonable supply of used bits in breakers. Intrusive vibration and noisy motor are signs of an engine about to die. Chassis starts to rot after the third British winter.
1987-89, 448cc DOHC twin, 40hp, 105mph, 50mpg, 380lb
