There is a primordial drive in certain motorcyclists that can only be satisfied by shoehorning the largest and most excessive engines possible into the frames of two-wheelers. The mighty V8, a staple of the muscle car world, has frequently found itself driving half the wheels it was designed for, but typically there’s been one glaring problem with the resulting motorbikes: they’re colossal.
Take the Boss Hoss, probably the best known V8 bike you can slap some money down and buy. Those things use engines up to 7 and a half liters in displacement, and you’d better bring a packed lunch if you want to walk around one.
Then there’s Nick Argyle’s Rapom V8, which uses an 8.2-liter, thousand-horsepower supercharged engine out of a freakin’ monster truck. That thing’s even bigger, and gets a hilarious four miles a gallon.
The best lightweight V8 bikes we’ve seen thus far have come out of Australia. Mad genius Ian Drysdale built some amazing home-brew motorcycles over the years, including a series of 750cc V8 bikes making 154-odd horses and keeping weight down to 210 kg without fuel. And the PGM V8 also made a fine show of things, cramming a 2-liter 12,800 rpm V8 into a trellis frame, tuning it for 334 horsepower and somehow keeping the fully fueled weight down to 242 kg (534 lb).
Britain’s Eisenberg Racing have added another to the list in the form of the Eisenberg EV8, and notwithstanding the cheeky incorporation of “EV” into the name of a petrol hog like this one, it looks like a pretty amazing machine.
