driver would start the car in "1st," then move the lever to "Hi" when desired. The Torque-Drive was discontinued at the end of 1971 and replaced by a traditional hydraulic automatic transmission. Other examples of semi-automatic transmissions based on hydraulic automatics were the Ford 3-speed Semi-Automatic Transmission used in the 1970–1971 Ford Maverick, early versions of Honda's 1976–1988 Hondamatic 2-speed and 3-speed transmissions, and the Daihatsu Diamatic 2-speed transmission used in the 1985–1991 Daihatsu Charade. Other examples Usage in motorcycles An early example of a semi-automatic motorcycle transmission was the use of an automatic centrifugal clutch in the early 1960s by the Czechoslovakian manufacturer Jawa Moto. Their design was used without permission in the 1965 Honda Cub 50, which resulted in Jawa suing Honda for patent infringement and Honda agreeing to pay royalties for each motorcycle using the design. Other semi-automatic transmissions used in motorcycles include: Honda's Hondamatic two-speed transmission fitted with a torque converter (which shares its name with several fully-automatic transmissions), as used in its 1976 CB750A, 1977 CB400A Hawk, 1978 CM400A and 1982 CM450A. Those in various minibikes, including the Amstar Nostalgia 49, Honda CRF50F, Z series, and ST series, Kawasaki KLX-110, KLX-110R, and KSR110, KTM 65 SX, Suzuki DR-Z50, DR-Z70, and DR-Z125, SSR SR110TR, and Yamaha TT-R50E. Yamaha used an automatic clutch system called YCCS on motorcycles such as the 2006 Yamaha FJR1300AE sports-touring. This system can be shifted either with the lever in the traditional position near the left foot or with a switch accessible to the left hand where the clutch lever would go on traditional motorcycles. The Can-Am Spyder Roadster's SE5 and SE6 5-speed and 6-speed transmissions. Those in several underbone motorcycles in the 1970s; the Suzuki FR50, Suzuki FR80, and Yamaha Townmate used 3-speed transmissions with a heel-and-toe gear shift. Some high-performance sport bikes use a trigger-shift system, with a handlebar-mounted trigger, paddle, switch, or button, and an automatically operated clutch. Some dirt bikes use this system, which is sometimes referred to as an auto-clutch transmission. These include the Honda CRF110F and Yamaha TT-R110E. The conventional motorcycle foot shifter is retained, but the manual hand-clutch lever is no longer required. Semi-automatic transmissions in dirt bikes may be referred to as "automatic" despite a lack of automatic shifting. Usage in motorsports Semi-automatic transmissions in racing cars are typically operated by shift paddles connected to a designated transmission control unit. The first Formula One
