It’s the most powerful production motorcycle ever produced, nothing else even comes close, but this missile on two-wheels is more than just the sum of its parts. The brainchild of Australian race engineer Paul Maloney, who spent two decades in the paddocks of the world’s premier racing categories, the PGMV8 is the ultimate street bike he came back to the Victorian bush to build. The carbon bodied, road-legal machine is a mechanical masterpiece, packing 334hp from its signature 2.0l V8. So to get the inside word, Pipeburn spent considerable time over the last six months getting to know the man and his machine.

From Sir Jack Brabham winning the Formula One championship in his own car, to Jeremy Burgess guiding riders to fourteen Motorcycle GP championships, Australian’s have been a dominant force in global motorsport. But the ever modest Maloney started his adventure in equally humble beginnings, in the BSB paddock doing all the dirty work to get a gig. He quickly rose through the ranks, first as a race engineer with the dominant Loctite Yamaha squad, before heading to the continent. There he had success in national and world superbike championships, before stints at Sauber Petronas F1 and Eckl’s Kawasaki, building and developing their MotoGP engine programs.

But for years Maloney dreamed of building his own motorcycle and I first wanted to know why a V8? “It’s the Aussie thing isn’t it”, he laughs. “I’d long had it in mind to build it from Yamaha R1 cylinders and heads, but I first drew it up based on a Kawasaki ZX-7RR, as they were the parts I had access to at the time.” When he left racing and came home to Australia the R1 had further evolved and Maloney selected the 2006 R1 engine with its five-valve heads as the basis for his V8 masterpiece. Each bank of cylinders sit at 90°, with a forward running five bearing crank at the heart of the perfectly balanced 1998cc V8 engine.

No stranger to solving challenges with crankshafts, Maloney was engine builder and race engineer on the only team to win a major championship with the famed Yamaha R7 homologation special. While reports flooded out for years from the major teams that “the crankshafts failed”, the Maloney built machine piloted by Christer Lindholm didn’t spin a single bearing using the same crank all year. Engine management too was inspired by his time in racing, having known MoTeC founder Richard Bendell for decades, “it will allow you to do almost everything, but keep it simple.” An engineers delight! With all the tuning of the M130 ECU done by Maloney, including the silky-smooth ride by wire.

Moving further back the gearbox presented a hurdle most couldn’t overcome, but always seeming to find a simple answer to the hardest problems, Maloney describes the solution, “essentially everything had to be turned upside-down, reversing the output shaft and the clutch shaft.” It would take a textbook to explain the process of building such an … Plus d’infos
