This is the Streetmaster by Champions Moto, it's a flat-tracker-extraordinaire and I'm yet to show it to anyone without having them instantly ask me what it is and how they can either buy it or build one just like it.
This bike, the BOTT XR1, is a great example of what could have been achieved had Harley-Davidson not axed its Buell division back in 2009.
When it comes to Harley customs, you'd be hard pressed to find more unique examples than those produced by DP Customs. Our regular readers will remember that we featured the work of DP just a couple of weeks ago with their beautiful Harley Cafe Racer...
Jeff Wolf, the proprietor of Wolf Creative Customs, started building race-specific motorised bicycles for his son a few years back, he decided that the standard frames and engines were unreliable and a little on the finicky side so he started building his own stripped back racers from the ground up.
We featured the official 2013 Triumph Scrambler last week, in the process of writing that piece I got to talking with Joao Alves of Somos and we pondered what a proper, balls-to-the-wall Triumph Scrambler designed to race across Baja would look like.
The 1930 Henderson Custom is one of the most stunning art deco motorcycles we've ever seen, it's based on a 1930 K.J Henderson with an inline-4 air-cooled engine, that bodywork is all custom and it's the sort of thing that would have impressed even Ettore Bugatti.
This is one of the newer customs from DP, it's based on a Harley-Davidson 1200 Sportster but looks like a totally new animal. The front forks have been lowered then topped with RSD clip-on handlebars...
Brett over at Hand Made Vintage Customs has a knack for building refreshingly unusual custom motorcycles, this bike is based on a 1980 Yamaha XS400 and it's a hybrid of both scrambler and tracker schools of motorcycle engineering.
I've made this comparison before, but Radical Ducati is to motorcycles what Skunk Works is to aircraft. The Spanish garage has been taking stock Ducatis and turning them into two wheeled missiles for years now and as such they've earned a deserved reputation as the single greatest custom Ducati garage in the world.
Chad Goings, owner of Goings Moto, recently set out on his own after doing an internship at Radical Ducati in Madrid. From a cafe racer perspective, an internship at Radical is the exact equivalent of a budding aircraft engineer doing an internship at Skunk Works.
