HONDA CBX 250RS (1982-1983) Specs, Performance & Photos

The Honda CBX250RS was a motorcycle sold by Honda in 1983 as a new 250cc sports bike, manufactured to replace the CB250RS. The CBX featured an XR-based engine with particular links to the XR350 bottom end, which included a six-speed manual transmission and the same oil pump.

Also, the stroke was the same, but the bore was reduced to lower the capacity at 249cc, and the balance shaft was removed, locking the engine with rubber mounts. Unlike the XR models, the top of the engine received two camshafts and two carburetors, but only one featured a pilot circuit.

The CBX250RS was sold between 1984 and 1986, along with the CB250RS, at a higher price and not notably better. The sales were not so good, with an estimated 300 units sold, soon replaced by the GB250, which featured a cafe racer style and successfully sold in Japan until 2000 with only minor changes.

The 1983 CBX packed a telescopic fork on the front and two shock absorbers on the rear, while the braking performance was handled by a 240 mm disc with a two-piston caliper on the front wheel and a 180 mm drum braking unit on the rear wheel.

In the power department, the 1983 Honda CBX250RS had its soul brought to life by a 249cc four-stroke single-cylinder air-cooled engine that delivered an output power of 31 hp with maximum strength at 9,500 rpm and 20 Nm (15 lb-ft) of torque available at 9,000 rpm.
