The Honda NSR50R was a small, 49cc, two-stroke pocket rocket like sportbike produced by Honda in 2004.


The engine was a liquid cooled 49cc two-stroke. A 39.0mm bore x 41.4mm stroke result in a displacement of just 49.0 cubic centimeters.


The bike has a 6-speed transmission.


It came with a 100/90-j12 front tire and a 120/80-j12 rear tire. Stopping was achieved via single disc in the front and a single disc in the rear. The front suspension was a telescopic fork while the rear was equipped with a swingarm with twin shocks. The NSR50R was fitted with a 1.95 Gallon (7.38 Liters) fuel tank. The wheelbase was 42.72 inches (1085 mm) long.
