Which are the Highest revving production motorcycles ever made?

Motorcycles engines are known for their high-revving nature. Since they are limited in size and slapping them with massive big-block motors like the ones you see on automotives is a non-option, they compensate for making that big power by revving higher than most cars out there. For most motorcycles, 8000 to 11000 rpm’s are a standard affair, and all current sports bikes rev happily at these ranges and push the redline a wee bit more too.
But you are not here for these, are you? Well, fret not. Top Speed has got you covered. Although emission laws make things like those an impossible dream today, the motorcycles we are featuring here will give you a glimpse of that very high revving creation of our pasts. And it all starts with the Big four’s from Japan. But of course!
