The Triumph factory did not support racing, but soon after the Second World War Ernie Lyons persuaded Edward Turner, chief engineer at Triumph, to provide him with a special engine for racing. As a result the factory upgraded a Tiger 100 with hot cams and pistons and some other modifications. With this bike Lyons went on to win the 1946 Manx Grand Prix. Based on the enthusiasm this generated, Turner further agreed to build a batch of 50 replicas for customer use. Launched in 1948 and called the Triumph Grand Prix, D.G. Crossley bought one and went on to win the 1948 Manx Grand Prix with an average speed of 80.18mph. The machine was based on the standard Tiger 100, but included many features that had also made the Lyons bike a winner. The light alloy engine was equipped with two Amal carburetors and a gear driven BTH-TT magneto. The oil and fuel tanks were enlarged. The brakes were also special, being 8 inch single leading shoe type.
This particular machine was originally supplied to the Jenkin and Purser Company of Portsmouth, England on 3 May 1949 with invoice number 18078. Records state that this bike was originally tested by J.A. Schoby. The subject of a high quality restoration by respected motorcycle enthusiast and bike author Vic Willoughby in the UK, the machine appears to be still very original and has been carefully rebuilt utilizing all original parts. In more recent years this bike has been in the collection of Ronald Weaver in California who purchased the bike directly from England. Unused since restoration, and in fact not even filled with fuel, this great machine would make an ideal display piece or would make a welcome return to the race track.
