Early 250’s weren’t too reliable and lacked style. 24 Hours had suspect alloy but could hit the ton on a good day. Desmo version a little faster than the Mk.3 but can wreck the big-ends and the crank. Useless carb, electrics and exhaust. Can break legs rather than start if the timing’s slightly out. 350 best buy but rare. All are agile and gutsy but rigid suspension and fierce primary vibes make them less than inspiring. Some very expensive renovations, used spares are rare.
