The Honda CB125 was a 122 cc (7.4 cu in) motorcycle made by Honda from 1971-1975 (1973-1985 in the US). It had an overhead camshaft (OHC) engine with a 9500 rpm redline. It could comfortably maintain speeds of 55 mph (89 km/h) and had a top speed of around 65 mph (105 km/h). 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 "S" model was produced from 1971 to 1975 and was replaced in 1976 by the "J" model (the US bikes retained the S designation). The newer model sported a two piece head, 124 cc (7.6 cu in) displacement, and a larger carburettor, but it did not perform as well as the earlier models.
Aside from different color schemes and minor lettering differences, these are some of the major design changes:
- 1973 - First year the bike was released in the US as CB125S0.
- 1974 - Front drum brake changed to disk, tachometer was added.
- 1976 - Engine displacement increased from 122 to 124 cc (7.4 to 7.6 cu in), tachometer was eliminated.
- 1979 - Front disk brake was changed back to drum.
- 1980 - Point ignition was changed to capacitive discharge.
- 1983 - The bike was not produced this year.
- 1984 - The electrical system was changed from 6 to 12 volts.
- 1985 - The last year the bike was released in the US, headlight shape was changed from round to rectangular.
