My friend Kevin Dunworth is building an epic superbike that is an aggressive marriage of old & new that is best described by the madman himself in this here video. Bucephalus is a bike that many will definitely be talking about very soon. Make the trek and see it for yourself at the 13th annual Motorcycles as Art show in Sturgis, August 5-11. The theme is ‘Ton Up! – Speed, Style and Cafe Racer Culture’, held at the Buffalo Chip.

“This is the first part of the story of ‘Bucephalus’. I’ve had a fascination with the story of the legendary horse Bucephalus (owned by Alexander the Great) for years–  if you are unaware of the namesake’s history, check it out.  It is an epic story, and I thought it would be a great name for this bike. Over the last four years, when time allowed, I was working on this project of a frame idea I had.

It started out as a joke, me calling it ‘Bucephalus’…and it just stuck. When Michael Lichter invited me to display in his show at Sturgis I had a deadline and a empty bank account. All my friends in the industry (and out) came together to help me build Bucephalus. This project means so much to me, I cannot explain. It might seem silly or stupid to a normal person, but I think motorcycle people out there will get it. I hope you enjoy…”  –Kevin Dunworth

Kevin Dunworth also built my Triumph Tramp which has a very brief cameo in the video


  1. Nice little film, this one does a very good job of representing actual work being done.
    I wonder what the bike will look like.

  2. Superbike to me suggests the last word in performance, where as this is always going to be compromised by the use of an ancient engine (which can’t be anything other than an aesthetic choice.) While I love that custom bike building is undergoing a renaissance, I’d love to see a little less conservatism – whether in the design of GP chassis for MOTO2 or projects like this that don’t seem to challenge the current zeitgeist for retro. In some ways, it seems like an inversion of the hand built superbikes of yesterday. From folks sticking Triumph engines in Norton frames through to the wonderful designs of builders like Harris, NWS and Spondon, the idea was to improve on the handling of the most fearsome motive power of the time. So cool bike? Sure. Superbike, not so much.

    • Joe, I hear what you’re saying. Here’s a fuller description of the design intent of the bike that can be found here…

      “…built around a vintage Triumph motor, the Bucephalus features a completely custom frame and sport bike geometary. The aim is to fuse the tactile feel of vintage machines with the modern responsiveness of the latest sportbike. Light enough to pick up by yourself, the Bucephalus is shaping up to be victory of form and function.”

    • its just supposed to be different and fun… thats all… if I called it the “Vintage different and fun bike” instead of “Vintage superbike” would that be better???

      • Hi Kevin,
        I like it man. Probably me just be anal and arguing superbike semantics…More power to you and good luck with the rest of the build.

  3. Hi JP,
    Yup, it’s a lovely project and I bet it will be fun to ride. Have a look at this – pretty much the essence of a lightweight superbike for me, built by a guy in a shed in the UK. The concept was 95hp / 95kg – similar kind of numbers to the old 250GP bikes. I’d love to see more stuff like this make its way onto the road…even though he was a 4 wheel maven, I’ve always liked Colin Chapman’s quote: “simplify, then add lightness…”

    Hope you get a kick out of this design!


  4. Sorry, but that film was a triumph of style over substance and did absolutely nothing to show anything about the bike. I’m with the Guitar Slinger. Hipster BS.

      • Amazing how the biking community which historically prided itself on embracing individuality, non-conformity, innovation, and freedom has become the biggest bunch of closed-minded, critical, tired-ass, whiny windbags out there. Sad really.
