    S&S has been building big bore kits since the 60s and has it down to an absolute science. Their latest efforts are aimed at the Milwaukee Eight® platform (2017 and newer big twins) and opens up a whole new level of performance for these engines. Combining a new design forged piston with their...

    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...

    Now available, a 50-state legal version of our popular 475 cam for M8 touring machines. Bolt-in cam pulls over 100 Horsepower and 109 lb-ft of torque and now includes a Powervision PV3 tuner with built-in tunes allowing for a simple set up without having to put the bike on a Dyno! To make it...

    Big lift cams can open up the high rpm potential of the M8 powerplant, but they can also add stress to the stock valvetrain geometry. Valve thrust and valvetrain wear in big lift cam applications drove the S&S engineers to design stronger, more durable components that will help you get the most...

    The Indian FTR1200 is one of our favorite new machines, inspired by their Flat Track race bikes and checking all the horsepower, technology and handling boxes this segment demands. Our latest for the FTR line is a technology move and allows the base model FTR1200 to enjoy the additional modes...

    Wanna ditch that dB reducer for some extra rumble? Or maybe you don't have it installed, and your neighbor gave you "the look" as you left this morning at 7 for work and rumbled past - we get it.

    The M8 engine is a powerhouse, but a low idle combined with a plugged up exhaust conspire to mute the true sounds of freedom this machine was designed to roar. We get that and created the GNX slip-ons with one thing in mind and that’s belting out the flag-waving, eagle flying song of the...

    We heard S&S Cycle this one under wraps for a hot minute and are finally ready to set it free. The S&S R&D team took their proven 2:1 SuperStreet exhaust internals and finally ported them over to the Sportster platform. None of the shorty system fluff that kills the power, they are here for the...

    Originally conceived by S&S founder George Smith, the Classic Two Throat carb and matched air cleaner served as a performance milestone in the v-twin space for over a decade. Now long gone, they are still a hot commodity for in-the-know chopper builders and have inspired the latest air cleaner...

    Big power can push even the most unexpected parts to their limits and the Rocker Arm Studs in the M8 engines are high on that list. S&S Cycle is the go-to for big power and is obviously an expert on the details that make sure it’s reliable. “The rocker arm stands on the M8 heads are a weak spot,...

    S&S Cycle’s El Dorado performance exhaust system is a 50 state legal high flow exhaust designed around our 4.5” Mufflers and stainless steel Header.

    Our popular Grand National muffler apps now include the latest generation of HD® Softail® models and we're now adding a lower dollar slash cut version as well. Expect a legit v-twin exhaust note and a healthy bump in Hp and torque (91Hp and 113lb/ft!). Available in chrome or ceramic coated black...

    Until recently, performance exhaust and 50 state legal have been mutually exclusive features forcing a rider to choose between making power and making sure factory warranties were not impacted. We say those days are behind us. Welcome to the new world order of high performance that marries a...
