General Info:
From humble beginnings in 1967, JIMS® has grown into one of the industry leaders producing performance parts, accessories, tools, transmissions, and high-performance engines all aimed at enhancing the Harley rider’s experience. Originally, Jim Thiessen worked as a machinist with the aerospace industry. As bikes were brought to the shop in the early days for repairs and mechanical problems, customers would come to Jim looking for hard to find parts, or higher quality American made parts. In the mid to late 70’s Jim committed 100% to V-Twin Motorcycles. Developing parts & processes is his expertise, so naturally he developed a reputation for precision machining in the motorcycle industry. Starting with just a few manual mills & lathes, JIMS now occupies several buildings totaling 50,000 square feet filled with CNC machines. JIMS employs skilled craftsmen running an amazing collection of high-tech machines such as CNC machining centers, lathes and inspection equipment, with state of the art design and engineering capabilities, prototype department, and testing facilities to ensure quality is the number one priority. Our development team is a diverse, experienced, lean team that includes expert machinists capable of both CNC and manual machining, along with programmers, engineers, mechanics, project managers, and research specialists; working together with precision instruments. Process control and work ethic assure consistent and precise quality. JIMS is familiar with critical and tight tolerances. Their parts are used and trusted worldwide, on a daily basis, in critical working assemblies. A very unique talent that JIMS has under their roof is their experience with combustion engine development and manual transmissions. JIMS has developed several motorcycle engines and transmissions and produced these products in the thousands. From ground-pounding burnouts, and high-revving scenarios, to everyday commuting, these parts are put to the test before ever being offered for sale. The JIMS brand is also involved in many different forms of racing, sponsoring some of the fastest Harley motorcycles on the planet including participants of the AHDRA and record holders in the BUB Speed Trials at the Bonneville Salt Flats. The research and development team is always searching for more horsepower, more reliable parts, tools, and new parts not yet available to the market and is committed to manufacturing as much as they can 'in house', which, in turn, guarantees the best American quality available. Company wide integrity is the foundation for JIMS everyday practices. Most of Jim's family works for the company, alongside a core team of talented employees that have dedicated the majority of their working career to this industry. Product quality and word of mouth have propelled JIMS's facility into one of the premier manufacturing venues in the country and is the key to their success story.
