Title: top speed for the S4R?
Post by: Clickjack on February 08, 2009, 11:40:11 AM
Anyone know what the top speed of a stock 2007 S4R T is suppose to be?

150 or so if I had to guess.  Prolly more on a dyno without wind...

That's it!?!?

A Caperex 620 could do 140mph.   [laugh]

The relationship between velocity and drag, which is governed by the square law which dictates that when a motorcycle's speed is doubled, the drag is quadrupled.

Figures are even more remarkable when you take a look at the extra power that is required in order to increase a motorcycle's speed. In this instance, the additional power required is proportional to the third power of the speed â€" or in plain language, a doubling in speed requires power to be increased by eight hundred per cent!

Massive increases in power are required for relatively small increases in top speed. 

Don Vesco is widely recognised as one of the world's most famous land speed record breakers on two and four wheels, and Team Vesco developed some outstanding Yamaha-powered streamlined machines in the 1970s.

Comparing the two streamlined machines, it can be seen that in order to raise the top speed by just over 50mph/80kph â€" the equivalent to a 25% increase in velocity â€" Team Vesco had to increase engine capacity by over 100%, from 700cc to 1500cc. 

That's 2 tz 350's vs. 2 Tz750's.

this thread needs rollie free.

if you were wondering exactly how fast 150 mph is... it was the record in 1948
