Even world motorcycling champion Valentino Rossi has revealed his fears that the sport's monster bikes, already over 900cc, are becoming too powerful.
After setting such a blazing pace at the British Grand Prix at Donington Park last week, before he had his victory stripped from him for a technical infrignment, the Italian said the four-stroke bikes, which are capable of speeds of up to 200mph, are becoming far too powerful to handle.
"It's possible to build four-stroke bikes with 300 horsepower tomorrow but the question is, who will ride the bike ?", asked Rossi. "Already the bikes are faster than last year and I think we are at the limit. At the moment it's possible to handle the speed of the bikes.”
“We're travelling five or six miles per hour faster than we were on the 500cc machines so the difference at the moment in the top speed is not very big. But 10 miles per hour more? No.”
"Over the last five or six years of the 500cc machines, the improvements came with the tyres but the bike itself basically remained the same. With the new four-strokes we've already been able to work out how to go one second faster at every race. That's very good but it also brings with it risks and there needs to be some rules so the bikes aren't built to go too fast."
