Yamaha Jog 50 cm³ AC
Yamaha launched the Jog 50 cm³ AC in Japan in 1983! It didn’t officially arrive in Europe until a few years later, equipped with a vertical Minarelli engine until 1990, then with a horizontal Minarelli engine starting in 1991. Ultra-compact and featuring a modern automatic transmission, it was immediately appreciated for its exceptional maneuverability and lively engine response—ideal for city riding.
PLEASE NOTE! We’re talking about the Jog here, not the Jog R, which appeared much later!
Yamaha Jog 50 cm³ AC - Engine Specifications
Please note: You need to be careful, as two different engine configurations existed on the Jog during the 1990s. There are two key periods to remember for Europe:
- 1988–1990: Minarelli vertical engine only
- 1991–1998: Minarelli vertical engine, then horizontal AC engine
Note: According to Yamaha, another version of the Jog called the “Jog Z” was available from 1992 to 1998, featuring a horizontal engine and a completely different fairing.
In both cases, this is an excellent base for customization, and above all, it’s an easy-to-maintain engine since it’s extremely common.
