With the Norton featherbed delivering awesome handling the '69 Harley Sportster Ironhead was in need of some performance improvements to make the most of it. An oversize bore increased capacity up to 900cc and an AMF high comp piston has been installed. A high lift street drag cam, oversized inlet and outlet valves and a Weber race carb with custom jet configuration boost power figures well beyond the engines ability in stock form. Custom mounts made from extra strong 1.5 inch steel plate secure the Ironhead in place and position it squarely in the centre of the frame to maximise balance. Despite the use of the Harley engine the Sporton weighs in at a mere 180kg making this not just one of the best looking but also one of the best performing Norley's we've seen to date.
