The Triumph Tina also known as the Triumph T10 was a small and low-performance scooter with a 100 cc (6.1 cu in) two-stroke engine, an automatic transmission, and a handlebar carry basket.



In 1962, despite internal opposition from those who felt it would dilute the macho image of the brand, Triumph introduced a new scooter, designed by Edward Turner, to tap into a strong demand that had been identified by market research for a simple and easy-to-ride "shopping basket" vehicle.

The Tina used a continuously variable transmission (CVT) system with a centrifugal clutch; the system had been patented by Turner and Triumph in May 1959. [4] The engine was mounted on the swingarm. [3]

An extensive marketing campaign was carried out, fronted by a pop star of the era, Cliff Richard.[ citation needed ] The Tina was marketed to women, and advertising focused on the ease of its operation. [5] Despite this the Tina sold in small numbers.[ citation needed ]

The Tina's patented drivetrain had technical problems. The CVT drive belt would derail and seize the transmission and the rear wheel, not only disabling the scooter but also preventing it from being pushed. Also, the starting procedure for the Tina required moving a switch on the handlebar to "start" before kick starting the scooter. This activated a governor to keep the engine speed too low to activate the transmission. If the switch were to be left in "drive" while the scooter was being started, then the motorcycle would accelerate immediately. This happened to Turner, resulting in a crash into a kerb and a broken ankle. [5]

The Tina was replaced by the Triumph T10 in 1965. The T10 included an improved CVT and the "start/drive" control moved from the handlebar to inside the seat, where the "drive" setting would be activated by the rider's weight. This weight-activated switched ensured that the rider was seated before the drive was engaged. This led to an embarrassing incident while demonstrating the T10 at its press launch. The switch had been set at 10 stone (140.0 lb; 63.5 kg), but the woman who was to ride the scooter away weighed only 8 stone (112.0 lb; 50.8 kg), the switch was not activated, and the scooter would not move. [5] The T10 was discontinued about 1970.

Three-wheeled prototypes

Triumph made a series of twelve prototype Tina tilting three-wheelers, similar in concept to the Ariel 3 moped. Disagreements between Triumph and the system's designer ended any plans for production. [6]

Velocette Defunct motorcycle manufacturer in the United Kingdom

Velocette is a line of motorcycles made by Veloce Ltd, in Hall Green, Birmingham, England. One of several motorcycle manufacturers in Birmingham, Velocette was a small, family-owned firm, selling almost as many hand-built motorcycles during its lifetime, as the mass-produced machines of the giant BSA and Norton concerns. Renowned for the quality of its products, the company was "always in the picture" in international motorcycle racing, from the mid-1920s through the 1950s, culminating in two World Championship titles and its legendary and still-unbeaten 24 hours at over 100 mph (161 km/h) record. Veloce, while small, was a great technical innovator and many of its patented designs are commonplace on motorcycles today, including the positive-stop foot shift and swinging arm rear suspension with hydraulic dampers. The business suffered a gradual commercial decline during the late 1960s, eventually closing in February 1971.

Continuously variable transmission Automotive transmission technology

A continuously variable transmission (CVT) is an automatic transmission that can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.

Triumph Tigress/BSA Sunbeam British scooter

The Triumph Tigress, also sold as the BSA Sunbeam, was a scooter designed to have good performance and handling for the motorcycle enthusiast. The entry of the BSA group into the scooter field was announced by Edward Turner in October 1958. The 250 cc model would have a cruising speed of 55 to 60 mph and petrol consumption of 120 miles per imperial gallon. A prototype 250 cc BSA Sunbeam was displayed at the 1958 Earl's Court Cycle and Motor Cycle Show. Manufacture started in late 1959, but delivery difficulties were acknowledged due to problems with recruiting labour, although it was claimed that the group had a manufacturing capacity of 50,000 machines a year.

A scooter is a motorcycle with an underbone or step-through frame and a platform for the rider's feet, emphasizing comfort and fuel economy. Elements of scooter design were present in some of the earliest motorcycles, and scooters have been made since at least 1914. Scooter development continued in Europe and the United States between the World Wars.

The engines had a reputation for vibration, but acceleration was good for the time, to a top speed of 100 miles per hour (160 km/h).
