Denis Manning’s motorcycles have been chasing world land speed records for over three decades and now the BUB 7 Streamliner he designed and built is the fastest motorcycle on the planet. Chris Carr set a new FIM world record & AMA national record at 367.382 mph thru the mile with an exit speed of 372.534 mph at the Cook Private Meet at the Bonneville Salt Flats Utah.
We got a chance to not only look over the car at the V Twin expo and talk to the BUB team, but the Biltwell/Lowbrow Customs booth was set up directly across from their display.....which meant I just drooled all weekend over this....
The Engine: The BUB Seven is powered by a custom V-4 engine. This engine is purpose built for motorcycle land speed racing. From a blank sheet of paper this engine was designed for one thing, power the world's fastest motorcycle. The maximum limit for this land speed racing is 3000cc. The engine also needs to fit in a space 18 inch x 28 inched so part of the initial design is to fit this compact space. The V-4 concept was used for two reasons, one to fit into the packaging and two the unique surface of the salt flats requires a engine with traction control. The engine is a big bang type so that the engine can gain traction then relax and then transfer power with the next power pulse.
Unlike drag racing one of the challenges in LSR racing is that the motorcycle has to make two runs; a down and return that make the average for the record, so the engine has to survive for both runs without any modifications.

I was out in SoCal last month staying with Wes from Four Aces and working on a new project. Got to meet some amazing people and see some really cool stuff as well. Here we are hanging with Fritz and his son at their place in Fallbrook. Fritz has been racing on the Salt for 40 years, he and his wife rule.
Acceleration was on the fierce side....What more needs to be said really?
For some reason my wife doesn't think these are cool, and I don't get it. Triumph pre unit timing gears, drilled for weight with beveled edges to give less drag. Does it make a difference? I don't know, but it sure looks cool as hell.
Lowbrow Customs is proud to present the Four Aces Cycle 2010 Bonneville Commemorative shirt. 100% of the proceeds from the sales of these t-shirts is used to support the Four Aces team to race their vintage Triumphs at Speed Week. The shirts are a natural unbleached cotton and are available in limited quantities. Get a super cool shirt and help support vintage Triumph racing at the same time!
I just wanted to share this article from an old Hot Rod magazine I have in my collection, being a hot rod and salt flats racing enthusiast as well as a motorcycle buff, I always thought this was slick as hell. Now I have to see if I can find a Triumph powered one out there.....
