The BSA Rocket 3 is a 750cc, triple cylinder, four stroke, street motorcycle manufactured by BSA. It is also called the A75 following BSA's A series of designations. Max torque was 44.99 ft/lbs (61.0 Nm) @ 6900 RPM. Claimed horsepower was 56.73 HP (42.3 KW) @ 7500 RPM.
The BSA version of the three cylinder model is distinguishable from the Triumph Trident in that the cylinders on the BSA are inclined forward. These multi cylinder machines were designed to be the flagships of the BSA/Triumph group but they were introduced too late, being outclassed by the Honda CB750K four cylinder. Any other year it would have been met with great applause, but the Honda stole most of its thunder. While the performance was good for the time, the styling was too radical, which resulted in disappointing sales. The Trident outsold the Rocket 3 five to one, so first year models of the Rocket 3 are comparatively rare.
The bike has a 4-speed transmission. Power was moderated via the dry single plate.
It came with a 4.10-19 front tire and a 4.10-19 rear tire. Stopping was achieved via expanding brake (drum brake) in the front and a expanding brake (drum brake) in the rear. The front suspension was a telescopic while the rear was equipped with a swingarm with coil-over shocks. The Rocket 3 was fitted with a 5.02 Gallon (19.00 Liters) fuel tank. The bike weighed just 454.15 pounds (206.0 Kg). The wheelbase was 56.3 inches (1430 mm) long.
