I'm just curious. The manual says top speed of 89 mph (142 kph) - has anyone actually topped out their MP3 500? The only reason I asked is on the freeway the other day I was just keeping up with the flow of traffic and I glanced down to see I was doing about 70 mph with no strain and plenty of throttle left.

I don't I'll ever have reason to go more than 75 (that would be on the rural interstate around here - and I doubt I'd even do that), but I do wonder of what speed the machine is truly capable.

There was a thread way back. Seems right at about 92 mph stock, downhill, tailwind and good karma...

On my 400 I have the extra washer in the variator in effect lowering the gearing. I can hit 87 mph GPS verified on flat ground at which point the rev limiter prevents going faster.

95mph verified just outside of Atlanta...greatest day in bike riding history in my life...it was during the EXTREME gas crisis in the South that lasted for a weekend or so. I rode 30 miles on the straightest highway in Georgia without so much as a car, truck, or cop anywhere...put my head down, tucked behind small windshield and WOT. I was coming OUT of the mountains, so the downhill prolly helped.

last year I had 97 on the GPS and it was totally stock. Last weekend I saw 107 on the speedo with a little left, had to back off cause of traffic. That is with 17 grams Dr pulleys, 1 mm fuzzy washer, K&N airfilter, And Givi windshield installed.

My husband said I was north of 90 coming back from Atlanta last summer on his GPS. It was open interstate, flat, and didn't feel that fast at all. I was just thankful to be out of traffic and had been riding WOT for about 20 minutes. It didn't feel that fast at all. We won't talk about the ease with which his Bandit dug in and passed me when he saw an LEO

I've seen a couple of reports on the internet that have Piaggio speedometers reading higher than actual at about a 10% error rate. I don't know if every Piaggio is like that but perhaps a GPS could verify how accurate your particular speedometer is.

The error is pretty consistent bike to bike. Find Jimc's pictures of the arrows on his to show real speed, they match what mine does.

You can always satisfy your curiosity by buying or borrowing a GPS

Garmin in particular has a Speedo screen and can hold the max MPH. I wish it had a stopwatch!

Yep, I've noticed my Garmin shows that the speedometer runs a bit high - 10% sounds about right.

Top GPS speed - 94mph - that was on the flat, no wind. Here's that photo again (marks are 30, 40, 50, 60, 70 mph):

89 gps mph, and at this speed I do not want to take my eyes off the road with the "small front tires"! Not flat land either. Did not check since Dr pulley rollers, are on it now.

At these dizzying speeds, has anyone taken the time to cast an eye on what rpm they happen to be pulling...??

Really curious

Thanks

When my speedo said just a bit over 150km (or about 95mph), my GPS said 89mph.

Flat ground, Highway 60 in Mesa, AZ.

Try doing 150 MPH, 100 is nothing. Once you get over 120 MPH the wind really starts getting bad and you better be laying on the tank.
Not on the MP3 of course.

My Z1 was supposed to do 143 so of course I had to try it. The head shaking at 135 scared the willies out of me and I vowed to never ever go that fast on a bike again.

I don't think I got that fast on my Z1 before I got the head shake. You must have had a steering stabilizer on yours.

When I did 150 MPH it was on a customers GSXR1100 that I had just done a tune up on and was going to a test ride. Those things would wheelie doing 60 MPH just giving it gas, I did not know that when I went for the test ride. Scared the shit out of me almost.

Speed
I haven't try it yet on the open road, but I know it will go over 90 mph, because I barely touch the trottle & it goes. I have done 65 in the city real easy.

I've done 95mph (readout) quite easily, but hitting bad pavement things get a tad sketchy, the thing bucks like an angry bronco...
