But of course, motorcycle engines are developed to rev high, favoring horsepower more than torque. That’s because two-wheelers don’t need a lot of torque due to their lightweight nature, and this Fiat 600 is no exception. Hillclimb Monsters claim the vehicle weighs around 580 kg (1,279 lbs) – about half as much as the curb weight of the Mazda Miata MX-5.
The motorcycle engine-swapped Fiat 600, the bigger brother of the Fiat 500, was taken for a demo run at the Skradin Hillclimb in Croatia – the same place where a Mercedes M111-powered Smart ForFour unleashed its 500 horses. From the onboard and outside shots, the car looked agile and swift. And the engine sounds deafening as the car flies through the long straights and round corners.
