The T-suffixed C15 from BSA is mainly addressed for the more adventurous among riders, who want to explore woodland tracks. Unlike the base model, it has a single seat, dual shock absorbers as a rear suspension, knobby tires mounted on its laced wheels and a smaller fuel tank, which allows it to achieve a dry weight of only 127 kg.
In the engine department it sports a four-stroke, air-cooled, 249cc, single cylinder powerplant mated to a four-speed manual transmission that can reach a maximum power output of 15 horsepower at 5000 rpm.
