The Husaberg FE650's liquid-cooled, short-stroke SOHC motor isn’t just a revvy lightweight, there’s excellent torque there, too. It punches hard when given its head, but its still flexible enough for threading through trees, though it lacks the wallop of KTM’s 450EXC. The six-speed gearbox seems like a gear or two too many for off-road use, but on tarmac it definitely counts in its favour.
