This 1984 BMW R80 G/S is a dual-sport motorcycle that is finished in dark blue and powered by an air-cooled 798cc opposed twin paired with a five-speed transmission. Equipment includes a driveshaft, a Monolever single-sided swingarm, a Brembo front disc brake, engine guards, an upswept two-into-one exhaust system, and a rear luggage rack with side-mounted BMW hard cases. The seller acquired the bike in May 2021, and is believed to be the third owner. Maintenance circa 2016 under prior ownership comprised rebuilds of the engine and transmission which included replacing the timing chain, ignition coil, and the neutral switch. Additional work since 2019 entailed replacing the steering stem bearings, rebuilding the speedometer and fork, overhauling the carburetors, and ceramic-coating the exhaust. Showing 55k miles, this R80 G/S is now offered at no reserve in Massachusetts with a spare set of unused Metzeler Sahara tires, the original owner’s manual, a tool roll, and a clean New York title in the seller’s name.
The front fender, side panels, and 5.2-gallon fuel tank were repainted in their original Dunkelblau (558) with orange and light blue accents. Features include a steel double-loop frame, both side and center stands, street lighting and mirrors, a shroud enclosing the headlight and instruments, a reupholstered two-up seat, a black rear luggage rack with integrated luggage mounts, and a pair of BMW hard side cases.
Wire-spoke wheels feature 21″ front and 18″ rear Akront alloy rims and are mounted with Pirelli Scorpion A/T tires. Suspension consists of a rebuilt 36mm leading-axle fork turning in bearings replaced in 2019, along with a monoshock attached to the Monolever single-sided swingarm. Braking components include a 260mm drilled disc and Brembo caliper up front along with a 200mm drum at the rear.
The black cross-braced handlebar sits behind an instrument cluster containing the ignition switch, a rebuilt MotoMeter 85-mph speedometer with dotted shift point markers, and indicator lights for the turn signals, high beam, charge status, oil pressure, and neutral. The five-digit odometer shows 55k miles, 50 of which were ridden by the seller.
The air-cooled 798cc opposed twin was factory-rated at 50 horsepower and 41 lb-ft of torque. Features include dual 32mm Bing carburetors, both electric- and kick-starters, and a two-into-one upswept exhaust system that was ceramic-coated in 2019. Additional service under prior ownership included rebuilding the engine and transmission, overhauling the carburetors, resealing the top end, and replacing the timing chain, ignition coil, spark plug wires, and neutral switch.
Power is sent to the rear wheel through a rebuilt five-speed transmission and a driveshaft enclosed within the Monolever swingarm.
A tool kit and an owner’s manual accompany the sale.
