  1969 TRIUMPH T100R 500 DAYTONA
  500cc Sporting Twin named after Triumphs success in the Daytona 200-mile races
• Notes:
  Edward Turners 500cc Triumph Speed Twin of 1938 was a milestone motorcycle. Overnight it rendered both thumping singles and indifferent multis obsolete and ensured Triumph led the world for the next three decades. In 1959 the 500cc Speed Twin became unit construction and this proved popular with racers, particularly in America. This culminated in Buddy Elmore winning the 1966 Gary Nixon the 1967 Daytona 200-mile races. When Triumph introduced unit construction in 1957 it was initially as the 350cc T21. This was a short-stroke design and subsequently formed the basis of the unit construction 500. The new 500 measured 69x65.5mm instead of the earlier 63x80mm and the short-stroke design proved eminently suitable for racing. Following the success at Daytona in 1966 Triumph embarked on a three-year period of refinement of the T100 resulting directly from the racing program. The most significant update for 1967 was the introduction of Doug Heles twin carb cylinder head for the T100T Tiger Daytona and US T100R Daytona Super Sports. The Daytonas new cylinder head featured the narrower included valve angle of the racer, and larger inlet valves, and parallel, rather than splayed, inlet ports. The stubs were splayed to allow a pair of "pancake" air filters. With a pair of E3134 camshafts and racing tappets the power for the T100R was 41 horsepower at 7,200rpm. Accompanying the engine updates was a new frame, also incorporating features from the Daytona racing bikes. The top and front tube diameter was increased, the top tube now leading straight to the steering head, and the steering head angle increased to 28 degrees. Along with a stronger swingarm, with a braced pivot, and an improved front fork, the T100 promised vastly improved handling. For 1968 the T100R received a two-way damped and a pair of 26mm Amal Concentric carburettors. Even more improvements appeared for 1969, notably the Bonnevilles 8-inch twin leading front shoe brake, plus a stronger bottom-end, hardened camshafts, new timing side ball bearing, and improved sealing of the pushrod tubes. This significantly improved machine was undoubtedly the finest T100 yet, and one of the fastest 500s available at the time. Motor Cycle in England achieved a one-way top speed of 107mph (172 km/h) in October 1968. This example is a US specification 1969 T100R. The build date was July 1969. The colours are correct for the year and apart from the Marzocchi shock absorbers this bike is very original. The centre stand is missing and the Smiths odometer reads 68779 miles. It is difficult to say if this is correct. The fuel tank is shows signs of corrosion and needs attention, bike was last run in 2018 and we are informed by Bryans its mechanically sound. The old hand painted South Australian registration plate reads TEO-923. This motorcycle was purchased by Bryan at a Shannons GP auction around 1990. This bike is featured on page 67 of issue No. 15 Sep/Oct 2009 of Old Bike Australasia. This motorcycle is sold unregistered.
