History
The Suzuki FA50 was a lightweight Japanese noped sold from 1980 through 1991. In Japan and some export markets it wore the Susie name. Suzuki stripped the fairings and two-speed automatic from the related FZ50 and FS50, aiming at simple, economical transport: foot pegs, a big luggage rack, and a single-speed transmission.
At just 46 kg (101 lbs), the FA50 pairs a 49cc reed-valve two-stroke making 2.4 hp with oil injection and a Mikuni VM12SH carb (#77.5 main jet stock). Depending on rider weight, expect roughly 28 mph stock. The stamped frame is not heavy-duty — broken or improvised foot pegs are common on used examples.
The enclosed driveline is the FA50's engineering highlight. Wet centrifugal clutch, chain, and reduction gears all live inside an oil-bathed case — low maintenance if you change the 500 ml of transmission fluid on schedule. Parts interchange with FZ50 and FS50 siblings, which helps keep survivors on the road.
Rear brake must be applied for the kickstarter to engage — a safety interlock wired into the brake cable. Treat it as a feature, not a fault, when diagnosing a bike that "won't kick over."
