Bugatti Veyron owners, have been looking very smug since the amazing supercar posted its awesome 250mph top speed and 1000 horsepower acceleration that not even the fastest motorcycles could match.
But it seems Acabion has taken the crown back for the bike brigade, with its release of a road-ready streamliner that's capable of beating they Veyron's top speed using only 20% throttle.
The Acabion GTBO is said to top out at around 340mph (close to 550kmh) if you're game enough to hold on to 50% throttle, and with engines varying from 350 to 750 horsepower.
It's very serious... Even if it does have training wheels.
"The Acabion GTBO minimizes weight and maximizes power and aerodynamic efficiency. The effects are just out of this world."
Manufacturers expect the GTBO to be in production and on the road within three years.
The bad news is the asking price is likely to be £1.5million.
