S&S V124


The V124 “Super Sidewinder Plus” is the biggest S&S engine that still fits in a stock Evolution Big Twin frame. Features bigger-than-stock 1.5″ crank pin and .927″ piston wrist pins, large fin packs on heads and cylinders, HVHP oil pump and electric compression releases for easy starting under any circumstance. Tests on the S&S Dyno have shown almost 129 rear wheel horsepower and an impressive torque of 137 pound-feet. A high-performance clutch must be used.


Need to replace a worn out Evolution Big Twin engine without breaking the bank? Or want to tear up the asphalt with a Dyno proven high-performance engine? Look no further as Route 66 Motorcycles offers the widest range of reliable S&S engines, ranging from 80CI (1,340cc) to an impressive 124CI (2,035cc). S&S has made the best combinations of bore, stroke, compression ratio, camshafts and so on and backs this up with a warranty of up to 3 years. These engines are nearly stock height, making them easy to fit in stock and stock style frames for 1984-1999 Evolution engines. All engines supplied with a Super E Carburetor, Super G Carburetor or with fuel injection come complete with an S&S teardrop style air cleaner. Carbureted engines also include an ignition as indicated. Engines do not include an alternator stator and rotor, install stock or aftermarket alternator.
