Dirt track on asphalt? What kind of oxymoron thought that up? Turns out a genius called Ken Lilly. We have a bunch of archive photos reliving the lunacy of life in MARS - Motorcycle Asphalt Racing Series. Then we bring dirt trackers on the hard stuff right up to date with two-time SuperHooligan champ Andy DiBrino tarmac drifting the stuffing out of his killer KTM 790 hooligan. We love the idea of it, but our collarbones tingle at the thought.

- Of course, there's plenty of dirt too,

- World's first test on the Herald Brute 500

- Deep dive into Royal Enfield's first national dirt track win

- Inside the collector cavern of Speedseekers Chris

- All shapes and sizes of dirt track race bikes from USA, Spain, Germany, Belgium and Japan

And all this!
