Ducati Desmosedici D16 GP4 2004
After the Ducati Marlboro Team’s successful debut in the MotorGP World Championship the previous year, with riders Loris Capirossi, Troy Bayliss, and test rider Vittoriano Guareschi, Ducati returned in 2004 with this new, improved version of the stunning Desmosedici machine.
The Italian factory had built an instantly competitive four-stroke machine in 2003 thanks to their years of success in the World Superbike series. Remarkably for just a single year of development, this 2004 version of the machine known as the D16 GP4, had had more than 60% of its 915 individual components totally overhauled (thereby making them non-interchangeable with the previous year’s model).
Ducati Corse Technical Director, Filippo Preziosi, commented at the time that the ‘experience gained in designing the GP3 was fundamental for the creation of the GP4 [and] while remaining faithful to the basic philosophy [he expected] that the all round competitiveness of the Desmosedici would be much improved’.

Norton ES2 500cc Single with Watsonian Side Car 1961
First produced in 1927, the ES2 was the mainstay of the RAC patrol service. It was a long stroke single engine originally launched as a sports motorcycle. The ES2 proved popular with the RAC due to its reliability and ease of maintenance. The Club’s 1961 motorcycle features telescopic front forks, swinging arm rear suspension and the famed featherbed frame coupled to a fiberglass sidecar, which was phased out in 1960s with the arrival of the mini-van. It had a capacity of 490cc and 25bhp. The last Norton ES2 was produced in 1964.
