High Speed Testing

[galahs]

I can verify the indicated speed on the stock 2005 GS500F is not the same as the actual speed.

I have it laser verified that at 100km/h indicated, I was actually doing 94km/h.



So my top speed of 190km/h indicated was more likely 178.6km/h

Interesting, I took my fairly stock 1997 Holden Commodore to the same section of road to see what it was capable off.

3.8Litre V6 (Buick) 147kw 304Nm
4 speed Auto

I could only manage 180km/h over the same distance, yet I know the car is capable of at least 205km/h.


So the GS has better top end acceleration than my car. I knew for sure the bike had the jump of the line, but this result surprises me!

What exactly is a "kW"?


I'm kidding, you Aussie!

All hail the metric system!

stock 2005 gs500f and hugging the tank like theres no tommorow

i weigh 160lbs and have taped the 130mph mark. once you get above the 120mph mark the needle shakes around a little bit(+/- 2-3mph) and is hard to tell exactly where it is.  it took me about 3 mins from first gear. I have to use up every bit of gear before shifting and i can only get above 120 if im hard on it starting below 30mph, cant go from cruising at 65 down shift and try to do it... it just dosent work. with no dampener its hard to do it long because the bike will pick up alot of wobble. I have done this maybe 3 times and don't plan on doing it again because with riding at such high speed on this bike there isnt much control at all, ur only riding on hope.

the gs500f wont keep up with the 600 gsxrs on the highway but it will rape them in cornering on the back roads.

I wouldn't doubt that if you have a road where you can hold it for 3 minutes!!!!


My test would be lucky to have gone for much more than 30 seconds.

[gsbarry]

Yeah I get that little wobble at around 160 + Km/h. You gotta hug the tank and pull up on the bars. It will smoothen right out. No hope required.

Theres been lots of roads where we are able to ride over 160 for more than a couple minutes. Only hit 180 indicated beside the CBR a couple times.

All hail the metric system! 

indeed power should be measured in Watts, not in animals.

Well, apparently American engineers love to have weird numbers in their calculations. Prolly makes them look smarter. Us SI types have lost the ability to memorize twenty-odd improtant technical coefficients.

I took my 05 GS500F for another high speed test today and I have noticed it was unable to match its previous best top speed  of 190km/h.

I could only muster 185! 


The only thing that I have changed since my last run was the wind shield. I replaced my stock screen with a ZeroGravity DoubleBubble.

The taller screen makes the air flow go up over the rider higher than the stock screen, so its highly likely it isn't as aerodynamic as the stock screen and this has restricted my top speed.

Thoughts?

Id like to see a GS do 130mph 

[galahs]

My guess is a turbo GS would be capable of 130MPH+

Didn't you change your jets back to 145 from 150?

Edit: I've had mine to 125mph indicated several times, I wonder what my actual speed was.

[galahs]

Oh yeah... you're right 

I guess that's why it can be silly making assumptions when you haven't completed back to back tests.

Most likely wind. A very gentle tail wind before, vs. no wind or a slight head wind this time would make the difference.
Or maybe you've put on a few pounds and aren't quite as aerodynamic as you were before.

The weather is cold up in stouffville (8c)...404 south, just ran 200km/h...with revs to go, had to slow....cops pulled over someone and i didn;t want to have to take a cab home. Jet kit- jardine rt-1 and lunchbox. Chin to the gas tank...bike gets pretty wobbley though...

[Jay_wolf]

I Saw 130+ Indicated , it went of the clock, with revs to go , that was when it had a standerd exhaust , Standerd Filter , Just rejetted

can wait until i test her agen

[galahs]

 

The GS can do 200km/h!!!!



How long was the road?
