Launched in late 1955, the Venom was the sporting development of the MSS, built to hold its own against the new British twins. It had a high-compression 499 cc engine with an alloy head, a well-regarded chassis and, from 1960, glass-fibre enclosure panels that purists disliked. It became the best-selling model of the late Velocette range and is now a prized classic single.
