Vmr Power Pack The Journey — So Far Part 12 2012 Vmr
Yes, the infamous TX750. By 2012, this model was considered a pariah due to its flawed balancer system. But VMR Part 12 took it on as a challenge.
The article traced one member’s two-year journey:
It remains one of the most requested reprints in the VMR library.
Another major chapter revisited the eternal carb debate. By 2012, original Amal concentric carburetors were causing more headaches than ever due to worn throttle slides and ethanol-blended fuels.

The results surprised many. While the Mikuni won on cold-start and fuel economy, the Amal Premier (with redesigned pilot circuit) delivered smoother mid-range—and kept the period look.

The Journey So Far subtitle wasn’t just marketing. Part 12 arrived at a moment when many founding VMR members were aging out of heavy workshop work. Younger riders were discovering café racers via YouTube, but lacked foundational knowledge.
The 2012 VMR Power Pack became a bridge. It said: You don’t need a $50,000 shop. You need patience, basic tools, and this book. Yes, the infamous TX750
By the summer of 2012, the VMR Power Pack was no longer a well-kept secret. Hydraulic distributors in Italy, Spain, and Poland began requesting demo units. Competitors—including Bosch Rexroth and Parker Hannifin—took notice. While those giants had deeper pockets, VMR had agility.
In September 2012, Hydraulics & Pneumatics magazine ran a cover story titled “The Silent Revolution: VMR’s Power Pack Outperforms at Half the Noise.” The article praised the VMR’s thermal management and called its diagnostics interface “a window into the future of fluid power.”
Sales figures for the 2012 calendar year (released internally by VMR in early 2013) showed 407 units shipped—a 210% increase over 2011. Notably, 22% of those sales were retrofits, replacing competitor units that had failed prematurely.
