How much power is enough" For BMW Motorrad, that figure currently sits at 199hp: the output of the class-leading BMW S 1000 RR.
That’s an intimidating number for mere mortals like us. But for Steven Decaluwe of Motokouture Motorcycles, it’s not nearly enough. So when BMW dropped an S 1000 RR off at his Belgian workshop, he knew exactly what to do: go overboard.

?BMW made it hard, presenting me with a high-tech sport bike,? says Steven, ?full of electronics, with an already superb chassis, engine and performance chart.?
?Being bored of the moderateness in the so-called ‘custom scene,’ I found my inspiration in starting from scratch?no rules, no expectations.?

As he stripped the bike down on the bench, Steven tried to figure out a direction for the project. ?I wanted to prove that the chassis and electronic riding aids are so extreme they can even tame a turbocharged engine,? he says. So that’s exactly what he did; after weeks of studying the bike, he installed a Garrett turbocharger with an electronic actuator connected to the ECM. And he did it stealthily too: the turbo’s neatly hidden away, between a custom-made fuel tank and air box.

But one does not simply install a turbo, so the engine management software and mapping had to be revised too. The engine was also blueprinted, and the compression dropped to 9.2:1??to ensure sustainability.?
Here are the new numbers: 296 hp at the rear wheel; 145 Nm of torque at 9100 RPM; and...
