Now the point is, and the rate its still accelerating after 130 I am stating that it is a physical impossibility for it to top out at 140something 160 seems more likely to me but I guess I'll just have to give it a shot

Not trying to be smart. Just answering your original question. Have a nice day.

I think you are going to be aero limited before it runs out of motor. With my FZ1 on a mile long airstrip, I was aero limited to about 156.

Is there really a point here?

Geez... that app says redline in top gear is ~155. So IF you can tuck in tight enough you might see that speed. The thing about aero drag is that it is NOT nonsense! The power required to overcome aerodynamic drag increases with the square of the speed. A 'sit up' motorcycle has a terrible drag coefficient (Cd) as compared to almost any other vehicle, so the aero drag is a huge factor once the speed is up into triple digits.

Yes, unless you've "fixed" your speedo it's likely off by at least 6% and at that, an indicated 130 is really more like 122. Also, realize that the ratio difference between each gear becomes less and less as you get up in gears. I.e. the speed increase is not a linear, if that makes sense. Speeds gearing is:
1st: 2.73/1
2nd: 1.94/1
3rd: 1.54/1
4th: 1.29/1
5th: 1.15/1
6th: 1.07/1

That's a decreasing, acceleration, slope and in the end, the rev limiter will determine your top speed.

IF you have sufficient power to overcome the aerodynamic drag at that speed.

(just to clarify)

Keep it civil D6Rider313 - that attitude is not welcome here.

My 05 Speedy would hit 145 on the GPS. The 07 I had was at 142. My 06 Rocket would just tip 135. It is what it is.

Finally, some data. Any chance you've checked the 'new' bike ('03 S3 w/Daytona power) with that GPS? Extra 30hp should give you something like 8-10mph?

FWIW, the top speed of the SV 650 was a bit faster in 5th gear than in 6th...I couldn't hit redline in 6th with my stock, unpiped, unjetted bike.

Even if you put taller gearing on the S3, you might not get much more, as you may find you can no longer overcome the extra drag. On the type of roads I enjoy riding, that's pointless anyways. Those of you with endless straight roads may differ in opinion.
