The most daring café racer – The BT03, based on a Harley Davidson Softail Fat Bob.
“Produced between 1977 and 1979, it is the only café racer in Harley-Davidson’s history, with only 3,133 made. I was fascinated every time I saw one on the streets of Paris.” – Sacha Lakic, founder of Blacktrack.

“The idea came from the motorbike that marked my childhood, the Harley-Davidson XLCR”.

The BT03 features a large number of bespoke parts, which have been designed not only to enhance the aesthetics of this bike, but also to dramatically reduce its weight to deliver exceptional handling and strong acceleration.

Blacktrack Motors designed all the aluminium parts: the fork tees, rear controls, backrest and mudguard brackets. Each aluminium part is meticulously designed in the Blacktrack studio, then precision machined on the CNC machine tool of one of our trusted technical partners.
