Recently got a cellphone mount and decided to check out my actual top speed with a GPS app (we all know those speedometers on the old shifties are utterly useless).

My recently rebuilt P200E topped out at 66mph going with the wind. Against the wind it was more like 58mph. It was a bit windy that day.

What's your model and top speed?

Sprint with 177 Pinasco 2 port...SIP road and 24/24 carb

Around 58....after that I think 'Do I really need to get there 28 seconds sooner for the risk of having to spend a weekend rebuilding my cylinder?'....so I slow down and take in the scenery

Faster than a Lithuanian truck on the M40 is all I care about. Trucks have a speed limit of 56 mph in the UK, but the ones from the east generally travel a bit faster, and having them overtake you can be very unnerving.

Low 60s on my 1980 stock P200 although anything over 50 mph scares the crap out of me.

Strange but I'm sure that is the truth.

Back in my hardcore scooter boy days in the late 80's early 90's I used to often hit the highway when travelling to a rally. Normally the backroads but sometimes you had no choice. I do remember easily keeping up with traffic on my 1979 P200e . Crap I wish I could remember the exact speed but I'm pretty sure I hit 70-75 mph. I did mess with the jetting but that's about it.

The scoot had 500 miles on it when I bought it from an old Italian guy for $500 CAD.

P200 62, Sprint 48, super 42, though someone following me in a car says over 50. I don't think that's accurate, but could believe knocking on the door close to 50 on a long downhill.

My P200 stock currently tops out at 63 mph without wind with the basic sport pipe I bought at Scootermercato with upping the jets a bit. I weigh in at 132lbs. I recall a GPS speed once years ago of 67. Just put in another speedometer from a perpetual project and itís accurate as the phone GPS.

I got clocked by a roadside radar detector-sign going 12mph on my Ď65 Allstate. I try to keep it under 15mph but the speedo bounces around!

Lots of funny answers, but probably not a lot of helpful answers thus far. We'll see if I can add value on either front. This is what happens when I'm bored, up early, and at the in-laws for Christmas.

For me on the Stella, max speed I've ever gotten it to was about 75 MPH on GPS, with more to go. It was pretty damn scary at that point, though, so I normally keep it under 70. Stock, it did 52 MPH at WOT. Now, it has changed gearing and pretty much everything else.

My VBB with a mild tune on the original 2 port motor also did about 50-52 MPH on GPS top speed, but that was more the limit of the gearing than the power output of the motor. I don't recall off the top of my head what it does with the LML, 22t clutch, Malossi 166, some other enhancements, and 8" conversion I have in it now, but looking at my gearing sheet, it should get up close to 60 MPH, not that I'm planning on taking it anywhere I'd need that kind of top speed.

I don't know about the sprint yet, but it's getting a rebuild and some Go-Fast love (Polini 177, long stroke cut crank, 24/24/, SIP RoadXL) before I find out, but it'll be interesting to see the outcome. Assuming that I get about 16 HP out of it, that will give me a top speed in the 68-70 MPH range at 7,500 to 8,000 RPM's. I do know that there's no way in Hell I'm going to try to find out until I upgrade the suspension and put some quality rubber on it.

The attached graphs are for me (220 lbs) on my Stella (230 lbs). The Horsepower Required at Speed, which is effectively constant across bikes, even with the significant weight difference (which plays into acceleration).

The pair of graphs take input from a GSF Dyno run and compares it to the gearing. According to that calculation, the top speed should be about 75 MPH. Windage would increase that figure by potentially 5-8 MPH or so on the upside and 10 on the downside. Having gone faster than that, I had either wind at my back, my dyno is off (possible) or I have errors in my spreadsheetery (also entirely possible).

It's close, though, which is good enough for me, and helps me when I'm planning a build, because once once the motor is built, the clutch is the only element that can be easily (no case splitting) swapped to tweak speed on the power curve & RPM's.

The house is waking up now (I'm in the UK this week), so that puts an end to my blather. Merry Christmas, everyone!

Hello.
Thanks chandlerman. Those graphs are very Interesing.
I have 2012 PX125E. SIP RD 2 Exhaust, Drilled air filter and Readspeed Zeus Ignition module. (My poor engine is on the Bench having nearly killed it).

I could get up to 60 MPH on the flat. The slightest incline or breeze would knock me down to 55 MPH. I could catch up with Lorries which in the UK are restricted to 59MPH. No way could I overtake them, the slipstream would virtually nail me to the rear wheels. My mate has a 200cc Rally and he can easily beat me.

Mostly stock P200. Eyeball ported with SIP road 2. I can hit 70 mph if I hunker down a bit but it's wide open throttle

Commuting from Berkeley to San Francisco on the Bay Bridge
I have a stock 1981 P200e with rebuilt motor by SF Scooter Center. Now the speed limit on the Bay Bridge is 50 which works out perfectly for the P200e. I can do 50mph anywhere but with no head wind 60, but 60 to 65 on the down sloops. I road this scooter to see World Super Bike in Laguna Seca this year with a friend, who was riding a BMW GS, and he told me that I was going 70 at times. I was surprised to hear that. Swanny

My Super 150 manages to get up to around the mid fifties, doesn't feel like it's going to kill me either at that speed. I'm around two hundred pounds though so I'm sure that affects the top speed. That is according to the speedo though, but I did replace the speedo gear so it should be SOMEWHAT accurate. Sometimes over thirty mph it likes to dance around though.

I took "FatAmy" my 59 Allstate VNA, to cars and coffee this morning, I could tell the scooter was liking the cooler 62 degree temperatures and low humidity we usually don't have in Florida so I pulled out the cell phone and checked the top speed. First run 43 mph, backed up by a second run at 39.9 mph, so ill go with a solid 40 mph. Completely stock and cases never split. Good enough for me.

I have found that the speedos used on the P150's and P200's (marked in km) is 100% correct compared to the speed given on my GPS app.

The highest speed I have recorded on my P150X with a 166 Malossi kit, modified gearbox and SIP exhaust, is 115 km/h (72 mph). (Level road, no wind.) A bit scary on 10" wheels!

Normally we travel at 80 km/h, which is a nice, safe speed.

I can somewhat ďone upĒ that unbelievable statement...I once had a P2 which had a speedo that ran slow! Thatís right, with 65mph on the GPS, the speedo read 58mph. Whatís the chances of that?

I'm reminded of the stopped clock story... every now and again there has to be one that - by complete accident - left the factory with a speedo that just happened to show the correct speed.

Chandlerman, I can see you are a bit skeptical. I will take some Vespa friends along and do a testrun this coming Saturday (weather permitting) to confirm my readings. The app I am using is SPEEDOMETER.

I'm not skeptical of you, but I've found that the most accurate vespa speedometers I've ever owned were the ones that were broken entirely.

They were dead accurate whenever I was parked or stopped at a light

GTS 2011 stock model...I get puckered and tuckered over 70mph. I don't "think" i've gone over 75. It's not the bike, it's me.

Though, on a good note I'm 215ish and she gets to 70+ with no problem.

Accuracy
Amazingly enough, my 79 P200 speedo is spot-on for 30mph and 40mph. I rode by a roadside camera a bunch of times to make sure I was at a constant speed. The 40mph was a little harder but a few runs were spot on. The speed limit was 30. I've also checked it with a gps dash for my phone and at 60mph, the speedo read 60.

For the record, this is the only scooter I've ever owned (or rode) that the speedo is accurate. Crazy....

I haven't checked for top speed yet but I've gone over 60mph a few times. All my riding is between the house and town, which is a 40 mph max zone....

Mine is as well interestingly. It's also a little high under 30 but a little low over 40. Very weird.
