State of the art cafe racer only lacks long distance comfort. Some race engines well knackered but good build quality means road use barely dents its capabilities. EXUP and chassis upgrade in ’89 and better suspension in ’94. Anything with more than 50 thou will have suspect brakes, rear shock, ignition, clutch and, maybe, valves if they haven’t been set – many bikes have never had the valves looked at, implode expensively. Noisy engines bad news, loose gearboxes normal, can blow under wheelies.
