After careful consideration, I’ve decided to close the workshop for personal reasons. This is a measured decision about what comes next for us.

I’m proud of what’s been built and I am genuinely grateful to every customer and member of the riding community who supported the workshop along the way. Your trust, loyalty and word-of-mouth support made it the success that it is.

I know this leaves a gap in town for motorcycle services, and I’m sorry for that. It’s been a privilege working on your bikes and being part of the local riding scene.

Thank you all for the support over the years. I appreciate your understanding and wish you all the very best moving forward.

The Ducati Cucciolo

In 1946, just after World War II, Ducati introduced the Cucciolo — a tiny 48cc engine designed to turn an ordinary bicycle into a motorized ride. Light, simple, and affordable, it gave post-war Italy a new sense of freedom and mobility at a time when the country needed it most.
What began as a clever solution for everyday transport became the first chapter in Ducati’s story — the modest starting point of a brand that would go on to define speed, innovation, and Italian design.

If you want the best performance from your EFI Harley, you cant look past the Thundermax ECM. No matter what modifications you have, or have planned in the future this is for you. Speak to us today at RPM to get your bike setup and dialed in.

ThunderMax is an industry award winning, performance ECM designed specifically for EFI equipped Harley Davidson® motorcycles. This highly advanced, stand-alone tuning system utilizes proprietary AutoTune technology with wide-band oxygen sensors to deliver unmatched performance and rideability.

Every degree and a half of throttle; every 256 RPM, there is a fueling point that is automatically adjusted. That means more control and a smoother running engine. With the built in barometric sensor you never have to think about ambient air changes. WideBand O2 sensors constantly read the Air Fuel Ratio and give live, real time feedback to the ECM. That means, no “accepting” the changes made to the map, once you key off the changes are written. The ThunderMax ECM is fully adjustable with our ThunderMax tuning software or can be used just by loading a basemap. The choice is yours.

The Evolution of the Chopper Motorcycle

Born out of post-WWII counterculture, the chopper motorcycle has become an iconic symbol of freedom and nonconformity.

Timeline:
1940s-1950s: Veterans modified Harleys and Indians, stripping parts and extending forks.
1960s: SoCal's chopper scene exploded, popularized by clubs like Hells Angels and movies like "Easy Rider."
1970s-1980s: Custom builders like Arlen Ness pushed design boundaries.
1990s-2000s: Reality TV shows reignited interest, with builders like Jesse James gaining fame.
2010s-Present: Advances in tech led to sophisticated, high-performance, and electric choppers.

Today:
The chopper remains a symbol of rebellion and self-expression.

The Harley Street Tracker project is done and dusted. We ended up going a little over the top from the original scope but who doesn’t love a turbocharged street bike that looks like a race bike.
