There appears to be no shortage of audacity in Australia, evidenced by at least three motorcycles from Oz that are powered by V-8 engines. The originator was Ian Drysdale, who first mated a pair of four-cylinder banks to a common crankshaft in the late 1990s. In 2015, we saw the intimidating Aurora Hellfire OZ26, powered by a home-built 2575cc V-8 claimed to produce 417 horsepower.

Drysdale V8: A Closer Look

Recently we ran across this latest V-8 from Oz, the PGM V8, which is the brainchild of Pat Maloney. After retiring from jobs as a mechanic in World Superbike and at Sauber F1, where he helped develop the ill-fated Petronas three-cylinder MotoGP engine, Maloney set forth building the bike you see here. Coincidentally, Maloney’s Maltec Performance Engineering shop in Victoria is only about 60 miles from Drysdale’s shop, located near Melbourne. Maybe Aussie audacity is found in vegemite…?

Maloney first began work on his V-8 project by pairing two ZX-7RR cylinder banks to yield a 1500cc mill, but he then discovered Yamaha’s mid-2000s R1 motor was equally as wide, so he decided to build a 2.0-liter V-8 for maximum FYF. The pair of Yamaha cylinder banks are joined at 90 degrees to a flat-plane crankshaft inside bespoke engine cases.


Maloney says the PGM V-8 produces a monstrous 334 hp at 12,800 rpm when rated at its countershaft, a reading location that typically falls between crankshaft power and rear-wheel numbers. Peak torque of 157.8 lb-ft is supposedly found at 9500 rpm. Engineering the gearbox proved troublesome, as the clutch shaft and the output shaft had to be reversed on the rear cylinder bank, which is offset slightly to the left.

That sweet V-8 doubles duty as a stressed member inside a chro-moly trellis frame mated to CNC-machined 7075 aluminum rear elements. Its steering-head angle is raked to 25.5-degrees and uses a 107mm trail figure, which is fairly sporty for a bike of this size, even if the 60.6-inch wheelbase is rangy for a sportbike. All up, Maloney claims a reasonable wet weight of 534 lbs.


Exhaust headers don’t get any prettier than these.

Noted motojournalist Alan Cathcart took out the PGM V8 for a spin in 2015 and pronounced its low-speed handling as ungainly but said it otherwise operated like a ungodly fast naked sportbike. Additionally, he described the bike’s oddball gearbox, surprisingly, as flawless. Cathcart, who has also ridden the 750cc Drysdale and the 1000cc version, says the PGM V8 sounds even better than either, which you’ll hear in the video below.


Translucent paint on the bodywork allows the carbon weave to show through.

Suspension is by Ohlins, using an FGRT301 48mm fork up front and a TTX36 shock in the rear. Marchesini forged alloy wheels are slowed by a pair of Brembo nickel-plated GP4 calipers biting on 320mm discs, augmented at the rear by a Brembo P4-34 nickel-plated caliper and 220mm rotor. Akropovic provides the titanium exhaust system.


Motec components are used for the ECU and the color instrumentation. With more than 300 horses to beckon, this is where you hold on tight!

Of course, anything this audacious will be priced out of reach for those of us with modest means, and that’s extra true for the PGM V8, which has a list price of – wait for it – $180,000! But one listen to the sonic delight of the flat-plane V-8 revving out might have you researching the prices you can get for a used kidney. I suggest fast-forwarding to the 1:30 mark when the exhaust music begins. In the meantime, I’d better start a GoFundMe page for airfare to Oz…

    Meh. Underpowered.

  • Starmag

    I normally like retro, and I sure don’t need 300+ HP, but that is a beautifully finished and styled modern bike. Plus the F1-like sounds are super sexy. Love the trans blue over carbon fiber. A shame it’s not $20k or so. To the Japanese manufacterers, ditch the sugomi, transformers, angles etc., this is where it’s at. Also, not all engines have to be black!

    If you can afford the $180k, you can afford to ship it back to Oz for servicing and ride your humble Motus until it gets back. Can’t wait for the MO road test and some Duke wheelies. I’ll grab a stubbie out of me esky and kick it rather than hold my breath waiting for that though.

    Kidneys aren’t getting that much on the donor end. I heard it on the radio something about an illicit donor program out of Serbia or somewhere there about.

  • Born to Ride

    I want this engine in a tube car like an Ariel Atom. Its insane power-to-weight ratio is kind of wasted on a 500lb one wheel drive vehicle. If they struggle to put down 250-270 hp in MotoGP with 10,000$ slicks that last 45 minutes, surely 334hp is going to light up those pitiful PP3 tires like a Christmas tree.

  • Chris Weiler

    I’ll also chime in with a meh….180k for unusable power and some carbon bits. The exhaust alone costs as much as my versys, those tires won’t last very long, and one tiny rock going into that unprotected radiator is going to ruin your toy. I’m all for dreaming big but put some sense into it as well.

    KTM Duke…

  • SRMark

    I’d still be interested in the Suzuki Stratosphere. Only 6 cylinders though. But it sure looked interesting.

  • Ulysses Araujo
  • TronSheridan

    This bike has been around for at least 2 years. Good to see MO on top of things.

  • They call it the World’s most powerful production motorcycle in the title of their YouTUBE video… to that I only have but two words: Boss Hoss

    • Mad4TheCrest

      Well, power per lb of weight they got that Boss Hoss beat, I think.

  • jeff benson

    One unmentioned benefit of the V8 is the perfect balance. Counterrotating shafts not necessary. Which is why V8s were so prevalent in cars.

  • john phyyt

    Biggest “gottahave” feature is unbelievable noise. Therefore ultra rich would be demanding correct seamless gearbox emulation. This seems anything but.

  • Mad4TheCrest

    Very Cool. Those Aussies are strivers.

    I admired a supercharged Ducati 999 ‘Super Squalo’ that made the magazine rounds back in the day. Here’s a link to a brief description:

    Keep it up Australia – the world needs more of this kind of crazy.
