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.  


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 [[Honda CB92|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 CB125K|Honda CB125K2]]. 


==Engine==
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).  

==Drive==
The bike has a 5-speed transmission. Power was moderated via the wet, multiplate with coil springs.  

==Chassis==
It came with a 80/100-18 front [[tire]] and a 90/90-18 rear tire. Stopping was achieved via single disc. two-piston calipers. in the front and a expanding brake (drum brake) in the rear. The front suspension was a  telescopic fork (31mm diameter) while the rear was equipped with a dual rear shocks with 5-step spring preload adjustment. 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.  

The '''Honda CB125''' was a 122 [[cc]] [[motorcycle]] manufactured by [[Honda]] from 1971-1985.
