The Honda CB125S was a single cylinder, four-stroke Sport Bike motorcycle produced by Honda between 1970 and 1984. It could reach a top speed of 75 mph (120 km/h). Max torque was 7.52 ft/lbs (10.2 Nm) @ 6250 RPM. Claimed horsepower was 10.19 HP (7.6 KW) @ 7750 RPM. It replaced the inline twin cylinder Honda CB125.


The CB125S came in two major versions the '71-75 "S" version and the '76 and later "J" version although the bikes in the US retained the S designation. It features an overhead camshaft (OHC) engine with a 9500 rpm redline and offers 100 mpg. It could comfortably maintain speeds of 55 mph and had a top speed of around 65 mph. The engine could last tens of thousands of miles with only minimal attention; however, the oil had to be changed regularly (700 miles) to prevent premature wear of the camshaft bearings. The newer "J" model sported a two piece head, 124cc displacement, and a larger carburetor, but it did not perform as well as the earlier models.


These are interesting as the side cam drive type engine is a lot lighter then the center cam chain type, the bore and stroke also favors higher revs and more performance. The weakness if this machine, rather like the CB92 before it, was the four speed box compromised its performance, and the lack of a rev counter was also a problem.

These problems were addressed with the very much rarer Honda CB125K2.


Engine[edit]

The engine was a air cooled single cylinder, four-stroke. A 52.4mm bore x 57.8mm stroke result in a displacement of just 124.7 cubic centimeters. Fuel was supplied via a overhead cams (ohc).

The CB125F was fitted with a 3.43 Gallon (13.00 Liters) fuel tank. The bike weighed just 282.19 pounds (128.0 Kg). The wheelbase was 50.98 inches (1295 mm) long.
