Are you acquainted with the remarkable endeavors undertaken by the UK's TTS Performance? If so, chances are high that you've encountered their flagship project, the TTS SuperBusa, a supercharged Suzuki Hayabusa that roars with a formidable 372 horsepower on the dynamometer, creating an unforgettable auditory and high-performance experience.

While aficionados of the Hayabusa might be hesitant to acknowledge it, a shop cannot thrive solely on two-wheeled marvels. Consequently, TTS Performance delves into crafting and testing a variety of aftermarket performance parts for diverse motorcycle models, a fortunate circumstance for those who own bikes beyond the Hayabusa realm.

Consider, for instance, the Harley-Davidson Fat Boy that came under TTS's skilled hands. Sporting a few Screamin' Eagle performance modifications in its engine cases, TTS not only introduced its supercharger but also implemented crucial supporting enhancements to ensure optimal functionality and stable power transmission. This involved additional oil coolers, including one discreetly nestled under the chin spoiler, an intercooler, a sophisticated clutch with a transparent cover, and more.

Now, onto the tangible results. When subjected to the dynamometer, this boosted Fat Boy exhibited an impressive output of 234 horsepower at 5,900 rpm, accompanied by a torque of 215 pound-feet at 5,300 rpm. To put it in perspective, a stock 2024 Harley-Davidson Fat Boy claims 94 horsepower and 119 pound-feet of torque. While the initial Screamin' Eagle mods likely added some power, the current figures are undoubtedly striking.

Providing a glimpse into the completion of this customized Fat Boy project, TTS also offers a tour of its workshop, revealing other ongoing endeavors. One intriguing project is a Yamaha Niken GT patiently awaiting its turn for a dose of supercharger magic. The anticipation for the outcome is high, promising a captivating transformation.

As an interesting side note, TTS Performance, based in the UK, is making waves internationally, even catching the attention of motorcycle enthusiasts in Ontario. The global appeal of their innovative projects speaks volumes about the impact and recognition they've garnered beyond their local borders.
