Why the 'Tourist Trophy' ?

Motor cycle road racing had been held on the Continent for many years, but the machines used bore no relation to those pioneer machines used on the road. Basically, they comprised as big an engine that could be held in a frame, two wheels and very little else.
It is said that a conversation between H. H. Collier, founder of the Matchless concern and the Marquis de Mouzilly St Mars about the need to raise the standard of touring machines, and not 'speed freaks' as used on the Continent led to the Marquis donating a trophy for the winning single cylinder machine to the A.C.C. (Auto Cycle Club), later re-named the A.C.U. (Auto Cycle Union). This trophy, a 2ft 10in-high silver statuette of Mercury, poised on a winged wheel, is still presented to this day, as the Senior TT trophy. Dr. H. S. Hele-Shaw offered another trophy for the multi-cylinder class, but this never materialised.
The machines were to be road-legal, with silencers, mudguards and an adequate toolkit to enable repairs to be carried out by the roadside with spares that they carried with them.
