That video has been making the rounds on many motorcycle boards. That sound should bring a smile to any motorcycle enthusiasts face.

OH MY GOD! Thats amazing! I didnt know bikes could go to such a high RPM! :shock:

Even before 1990, the Japanese manufacturers have had 250cc 4 cylinder 4 stroke street bikes revving as high as 19,000rpm and 400cc 4 cyclinder 4 strokes revving to 16,000rpm.

It's about time their mainstream 600cc bikes began to be engineered as well as the 250's and 400's of 15 years ago.

mine cuts off around 15,500 :roll:

Which is why I say - it's about time the mainstream 600cc bikes got to where the 250's and 400's were 15 years ago.. ;)

Well you know that it's always easier to get a lower cc engine to rev higher, since the higher the engines cc's the more vibration it has to endure. And those engines were rebuilt every race i assume, and if not, at least every season.

Thanks for the explanation :)
Im a noob in bikes :oops:

That bikes 15 years ago has carburetor, that is an other story I think. I haven't want make flame war.
But if you hear this on the streets reving with a race cup you understand what is the "holly fucking shit" feeling. :)

I am talking about street nbikes.

Stock street bikes - in 1987/88/89/90/that revved to 15, 16, 17 and 18,000rpm.

Well now that's upsetting to hear, was their power output as good as their revs? And why the reversal in engine revs?

smaller piston=less weight.

it takes less force to accelerate a piston in a 250cc 4 cylinder engine than it does in a 600cc engine.

so... too accelerate a 600cc 4 cylinder piston to the same rpms as even a 500cc 4 cylinder piston, you need heavier conecting rods.

and that makes the moving mass heavier...

which take more force to acclerate...

which means you need stronger parts...

so in order to produce a reliable 600cc engine, engineers needed to figure a way to process the materials they had (or come up with new ones, which in some cases, they did) to come up with stronger, lighter parts.

and to be able to do that... in a cost effective, manufacturing solution that could be reproduced a million times.

not possible back in the day.

if they could.

they would have.

edit: oh yeah. cool vid. but as usual yamaha has set their rev limit too high as it sounds like its running out of ooph before even 500rpms before.

we need honda to redesign the engine in their rr. (i'm sure there's good reason why we're waiting though. :D )

Well the top hp is at 14.5 and i think the extra revs are really just to prevent bouncing off the rev limiter and give extra play in the turns. I would think it would be better to shift at 15.5k instead of 17.5k on this bike.

Can you give examples of street bike that revs to 19000rpm?

I had a CBR400RR that runs out of breath at only 12000rpm.
