Steve Mouritz

Steve Mouritz – Owner, Mechanic
and Motorcycle Suspension Guru

Steve’s passion for motorcycles began trackside at a young age, watching his uncle Jeff race motocross. That early exposure ignited a lifelong commitment to two wheels—one that has shaped a career built on performance, precision, and results.

Starting his motocross racing career at just 16, Steve went on to compete for over 30 years at the high levels of the sport. He concluded his official racing career in 2012 at Coolum with a standout win at Round 10 of the Australian Vets Championships, riding a factory Suzuki. Throughout his career, Steve consistently ranked among the top riders in the Western Australian State Titles and achieved strong results in Australian and Indonesian championships, earning a reputation for both speed and technical expertise.

Steve’s mechanical journey began in 1988 as an apprentice motorcycle mechanic with Rick Gill Honda. In 1999, he founded Joondalup Motorcycles (JMS), starting as a small workshop before expanding into a Suzuki dealership in 2006. His early focus on motorcycle suspension quickly became a defining strength of the business.

After 12 successful years operating as a dealership, Steve made a strategic decision to return JMS to its roots—shifting his full attention to high-performance motorcycle suspension, precision bike setup, and expert mechanical services. This move allowed him to deliver a level of detail, personal service, and performance tuning that only decades of real-world racing and workshop experience can provide.

Today, Steve works with riders across all levels and ages —from competitive motocross athletes chasing podiums to experienced riders who simply want their bikes to perform at their absolute best. With strong industry networks and a long history of mentoring and supporting upcoming riders, Steve and JMS are trusted by those who demand performance, reliability, and expert advice.
