How to blow up your Bike – the Buell XB9S Turbo


Boooooooost! By Hillbilly-Motors.

Where the name is actually exactly what you get. Many riders wanted to keep the short stroke but have a bit of extra power. Even with extensive engine work, you wouldn’t get much more than 1120cc. Sooo… A turbo charger – right?

Right. 115-120hp was the result of a very successful experiment. Hillbilly-Motors provided a complete turbo charger kit including of course the turbo, intercooler, intercooler management and indicator, engine management oil connections and tubing, exhaust and tank cover.

The XB9S Turbo was definitely a worthy successor of Jens’ turbocharged Buell 1200 RSS and a predecessor for the supercharged XBK.



For those who don’t know: before we moved to Sweden, we used to own Hillbilly-Motors – the single largest supplier of Buell after market parts in the world. The company was sold in 2006, the same year we moved from Germany to Sweden. We decided to collect all official project bikes here as well – just for fun really!
