Performance Times

    The M8 engine platform is capable of serious power, but with that also comes the need to beef up critical moving parts in the top end. The latest from S&S Cycle does just that by combining our roller rockers, bearing quality rocker shafts, rocker arm studs, and cold-formed head bolts into one...

    Shortly after the Royal Enfield 650 Twin was launched, the crew at S&S Cycle began pounding out performance parts! Our latest is the Qualifier, an all-stainless 2:1 exhaust that looks and sounds the part. Hand fabricated in the US, each system is a TIG-welded brushed stainless piece of performance...

    Big bore engines are all about the flow, more air in and more air out, anything that slows that down, robs horsepower.

Combining a new design forged piston with their 4.25”...

    Several years of development and thousands of hours of testing have fine-tuned the latest S&S Cycle Cam Chain Tensioner for the M8 platform. Larger piston diameter, tighter tolerances, thicker shoe material, and built-in direct chain oilers make the new S&S hydraulic chain tensioners the best...

    Big horsepower numbers are the status symbol of a performance engine, but more often than not, torque is what you really feel when riding it. This is particularly relevant for the heavy touring machines as it’s torque that rockets you onto the highway and it’s definitely torque that lets you...
