According to Bennetts et al. the Fastest Bike in the whole world is.....(drum roll please) 1. Kawasaki Ninja H2/R Claimed peak power: 322 bhp Estimated dry weight: 193 kg Power/weight: 1.585 bhp/kg The king is dead… long live the king. Last time out the astonishing, £49,000, supercharged H2/R came out top and, although the competition is closing in, it remains there today – just. Kawasaki set out to produce the world’s most powerful production machine and it achieved just that. In full bore, track only ‘R’ trim, the Kawasaki is claimed to produce a whopping 306bhp, rising to 322bhp with ram air effect. That, combined with a lightweight, tubular steel trellis chassis (although that 193 dry figure is a guesstimate based on its published 216kg wet figure) is what keeps it on top. If you’re going to quibble about its legality, the road legal H2 Carbon (£28,500) produces 240bhp with a heftier 215kg estimated dry weight although that would leave it outside the top 10 here…
