    GS400

    The Suzuki GS400 twin was presented in October 1976, being one of the first four-stroke Suzukis since the Colleda COX in the 1950's. The other Suzuki four-strokes that were introduced that year were the GS750 and GS550 fours. All three of them had similar appearance and specification other than the GS400 had a cross-mount inline twin, six-speed gearbox and drum rear brake. The 550cc and 750cc versions had five speeds and disc brakes front and rear. All GS models had two valves per cylinder, double overhead camshafts, tubular double cradle frame, telescopic front and pivoted-fork rear suspension, fuel gauge, gear indicator and electric start.

    Old Bike Barn offers a wide selection of parts to keep old motorcycles on the road. Things like engine gasket sets, carburetor kits, fork seals, levers, cables, brake pads and more to help you resurrect and maintain your Suzuki GS400.
