I've always been addicted by motorcycle racing, and starting having interest in flat track racing when I heard Kenny Roberts, in the early ’90s, talking about the skills it gave riders. My company, BCKustoms was born and started building race inspired custom motorcycles when I retired from world  championship motorcycle racing in 2009, after seasons as a mechanic and later team coordinator.

 

After years riding on racetracks, and later in working in pit lane, I attended the 2012 AMA Flat Track in Daytona and saw there was no greater series and that small added tricks combined with big balls riders helped to make a great show. I decided then to start building my first street trackers and looking closer at the flat track racing scene and what Sideburn created the same year with its first Dirt Quake.

 

I had the Sportster engine in an OEM frame at the workshop from back in 2009 and it was supposed to be part of my own ultimate tracker that I would build when I had the time. Then I started to notice hooligan racing and, after a first contact with the new French flat track scene and Vintage Racing Spirit in Lyon last February, I decided to build that project for the upcoming Dirt Quake VI.

 

As the hooligan rulebook describes the main frame cannot be modified, so I had to find the correct items to best fit a roadster frame and turn it into a real flat track racer. First I ‘built’ the bike to scale on a computer to adjust overall proportions and set all the details, then the parts were gathered on a budget to start building the bike.

 

The bodywork parts were bought long time ago, but the first fuel tank ended up being used on the BCK-014 XS500 Street Tracker and I needed a replacement from the Redmax Speed Shop.

 

As per BCKustoms’ signature, the stainless exhaust system has been made from scratch, this time to match the new factory Harley-Davidson XG750R design, giving the 30-year-old model a modern touch. The paint scheme was inspired by 2016 Rogers Racing XR750 AMA racer, ridden by Jared Mees.

 

But this racer is not just a Hooligan Racing machine. I wanted to build a nice looking tracker that I can display and have people in my home area of Brittany, France start talking about flat track racing, the DirtQuake event and this awesome sport's growth. I want to raise enough interest for oval racing in his area and get to the next level: building a local race track.
