At BSK SpeedWorks we create performance inspired, handmade, bespoke motorcycles for the road or race track. We think a well engineered machine, built to perform well, should be the basis for a custom built bike. You then tend to find that form follows function. As well as our custom classic motorcycle services, we are also pleased to be able to offer a range of performance parts for the BMW K100 and other K Series bikes, which now allows us to safely unleash the full potential of this well built, under stressed motor without sacrificing rideability or reliability.
