What JIMS does
JIMS USA is a Camarillo, California-based manufacturer of precision performance products founded in 1967 by Jim Thiessen, originally a machinist from the aerospace industry who committed fully to V-Twin motorcycles in the mid-to-late 1970s. The company's core offering consists of three product families aimed exclusively at Harley-Davidson motorcycles: high-performance Twin Cam Race engines available in 120", 131", and 135" displacements; 5-speed and 6-speed transmissions including the Fat 6 Six Speed; and an extensive specialty tools catalog supporting engine rebuilding, transmission work, and routine maintenance across Knucklehead, Milwaukee-Eight, and intervening platforms. Supporting components include forged aluminum pistons, hydraulic tappets, billet oil pumps, camshafts, flywheel assemblies, Signature Series titanium pushrods, and Forceflow cylinder head coolers, with ISO 9001:2015 certification underpinning the quality system.
The business operates from approximately 50,000 square feet of manufacturing space containing CNC machining centers, lathes, and inspection equipment, supported by in-house design, engineering, prototype, and testing capabilities. JIMS employs over 80 people, including skilled craftsmen, machinists, engineers, mechanics, project managers, and research specialists, with multiple members of the Thiessen family among the staff. Products are sold exclusively through an authorized worldwide dealer network; the company does not sell retail or direct to consumers and requires dealers to hold proper business licensing, retail tax certificates, and physical storefronts. Volume-based order discounts scale from 2.5% at $700 to 10% at $5,000, with $10 service charges on orders under $100 within the continental US and $500 minimums outside the US.
Revenue is generated almost entirely through B2B hardware sales of aftermarket parts, tools, and components to motorcycle dealers, repair shops, and distributors; pricing is unit-based via dealer wholesale with no subscription or recurring model. Marketing activity centers on industry event participation (ChopperFest, Born Free, Australian V-Twin Expo), racing sponsorship (AHDRA, BUB Speed Trials at Bonneville Salt Flats, and a roster of named individual riders), downloadable PDF parts and tools catalogs, YouTube product videos, social media presence, and a dealer locator on the company website.
