Bolt on 50-75%+ More HP! 

The icon of American V-Twin motorcycles–the Softail®–with its long front forks, authentic styling, nostalgia and swagger. All great stuff, right? Combine the unmistakable look of these legendary bikes with the unmistakable power of a ProCharger Intercooled Supercharger System and get ready to grow that legend even more by bolting on 40+ additional horsepower.

An American Legend Meets Legendary Power

ProCharger has substantially raised the performance bar. ProCharger HO Intercooled systems and tuner kits are not only the easiest, quickest and most cost effective ($/hp) method to increase performance on stock and lightly modified V-Twins, they also take modified V-Twins to performance levels never previously achieved on pump gas. Softail with a high-performance edge. Cool air is better. With engine-friendly intercooled boost, you can run stock timing and 91 octane fuel on most existing motors without having to fight detonation. Stock or modified, nothing else even comes close.


ATI’s ProCharger system offers excellent craftsmanship and comes as a complete bolt-on kit.” - Hot Bike
