What S&S Cycle does
S&S Cycle, Incorporated is a privately held U.S. manufacturer of high-performance aftermarket parts and complete engines, founded in 1958 by George Smith Sr. and headquartered at 14025 Cty Hwy G, Viola, Wisconsin. The company engineers and produces throttle bodies (52–70mm Throttle Hog line), billet fuel rails, Stealth air cleaners, MK-Series crankcases, big bore cylinder and piston kits (129"–136"), Variable Pressure Plate clutches, Super Stock cylinder heads, exhaust systems, and crate engines (including T143 and MK136) targeted at Harley-Davidson Big Twin and M8 platforms, with select expansion into Indian, Triumph, Royal Enfield, Honda, and Polaris applications.
The company's underlying technology is rooted in proprietary V-twin engine and intake/exhaust design — sealed stainless-steel throttle shafts with dual roller bearings, 6061 billet aluminum fuel rails with increased fuel capacity, large-volume crankcase sumps for improved oil scavenging, and cylinder heads with S&S-ported high-flow intake/exhaust valves — all intended as direct OEM-replacement fitment maintaining stock engine geometry.
S&S Cycle monetizes through one-time hardware sales at premium price points (fuel rails and accessories ~$100–$350; throttle bodies ~$400–$1,000; complete engines and crankcase assemblies $2,000–$2,850+) via a nationwide authorized dealer network (with dealer locator, portal, and application process) and direct e-commerce on sscycle.com (with international shipping and a military discount program). Customer segments span Harley-Davidson enthusiasts and modifiers, drag racing and land-speed record holders organized via the Proven Performance Club, professional custom builders, and authorized dealers. Marketing relies on the Performance Times blog and podcast, multi-platform social media, and racing event sponsorships. The company maintains CARB Executive Order compliance to enable 50-state legal sales.

S&S Cycle competitors and assessment
Company assessmentDirect peers
- Vance & Hines: Direct competitor to S&S in Harley-Davidson performance exhaust, fuel management, and intake systems. Vance & Hines overlaps S&S in slip-ons, full exhaust systems, throttle bodies, and EFI tuning products for the same H-D Big Twin/M8 platforms.
- Feuling Parts: Direct peer in H-D V-twin engine performance components, including camchests, oiling systems, and big bore kits. Feuling overlaps S&S in the engine-internal performance category and competes for the same high-displacement engine build market.
- Performance Machine: Direct peer focused on high-end aftermarket wheels, brakes, and chassis components for Harley-Davidson cruisers. While narrower than S&S, Performance Machine serves the same premium custom H-D customer and is often specified alongside S&S engine parts in custom builds.
- Kuryakyn: Direct peer in the Harley-Davidson and metric V-twin aftermarket. Kuryakyn sells performance and accessory parts across intake, exhaust, and engine categories that overlap with S&S's broader catalog, often distributed through the same dealer network.
- Roland Sands Design: Direct peer in the premium H-D performance and custom parts market, including exhaust, intake, and engine components. Roland Sands Design competes for the same high-end custom Harley builder and serves a similar lifestyle-branded customer.
- Arlen Ness: Direct peer in custom Harley-Davidson performance parts and accessories, including engine, exhaust, and air intake components. Arlen Ness competes for the same custom builder and enthusiast customer as S&S in the premium H-D aftermarket.
- Bassani Xhaust: Direct peer in H-D performance exhaust systems and related engine performance components. Bassani competes in the same 2-into-1 and slip-on exhaust category that S&S occupies with its Diamondback, Qualifier, Grand National, and other exhaust lines.
- Trask Performance: Direct peer in Harley-Davidson performance parts including intake manifolds, camshafts, and engine components. Trask competes in overlapping engine performance categories for the same H-D Big Twin customer.
- Baker Drivetrain: Direct peer in high-end Harley-Davidson transmission and drivetrain components. Baker serves the same premium custom builder customer as S&S and is frequently used in combination with S&S engines in complete performance motorcycle builds.
Broad incumbents
- Drag Specialties: Broad incumbent V-twin aftermarket distributor carrying hundreds of brands across parts and accessories. Drag Specialties is both a competitor (its house brand and private-label lines overlap with S&S categories) and a channel partner through shared dealer relationships.
