My understanding, in Australia anyway, is that the speedometer must read from the true speed up to 10% + 4km/h faster. So if your true speed is 100 km/h then the speedometer can legally read anywhere between 100 km/h and 114 km/h. It is not allowed to show an indicated speed less than your true speed. I have compared the speedometer on my Vespa GTS 150 against a GPS and it seems to be 10% low so I tend to ride 10% over the speedometer indicated speed.
So in your 30 mph example, I would be sitting on 33 mph. At 50 mph I would ride at 55 mph
Excellent advice here!
Where I live, the speedometer is not allowed to show higher than speed but allowed to be up to 5% low.
I'm a bit late to this but yeah you are correct. It's part of the Australian Design Rules.
What a fun experiment! I had no idea scooters' speedometers were off that much.
All manufacturers are allowed a percentage from the actual speed. Most opt to make it slower than the shown speed. After all of it was higher then the shown speed they could be liable for speeding tickets/accidents.
I am really surprised that it's off by that much! When I bought my 2nd minivan, I had been used to using my GPS (old style Garmin) and the speed always matched. When I bought the new (used) van I was surprised it was off. Turns out the dealer had put a slightly different size tire on it than the factory tires and it messed up the odometer reading. I made them switch the tires and it was right on with the GPS!
Thank you for taking the time to do this fun little experiment!👍
My pleasure! Scooter fun for the win!
I,m amazed the vespa was within 4 , if you think those are bad try the speedo on a px ,they were rubbish from day one , eating the nylon gear and turning the speedo into a geiger counter,as for lambretta lol it`s a wish to have a one that works ,
Lol thanks for the shout out . I ride nearly everyday and being aware of my surroundings/predicting has saved my rear many times. Today I’m building a backrest for my Burgman. Getting it ready for a 2X iron butt bun burner gold from Dallas to San Diego and back. Great videos 👍👍
Whoa! That will be a heck of a ride! We are looking at the logistics of riding up to Minnesota for Amerivespa. I’m prepping for a San Antonio or Austin for my first long ride before I commit to Minnesota! 😆
LoL remember me from your Blue Kymco 150i review, I mentioned speedometer was off, I mentioned if I was aerodynamic leaning down I got it to 60 , but speedometer said 65+ ..
Great video Great Channel
Ha! Thanks & yes! I didn't ride the Like hard, but you called it!
A similar radar device is located not far from my house. I have a Yamaha Zuma 50FX which I found to be reading high on the speedometer by about 3-4 mph. This summer, I bought a Honda ADV 150 which runs true to the posted radar speed. Liked and subscribed. ;)
Aren't those signs fun?! I am surprised the Honda was close to the speed yet the Yamaha wasn't. Interesting... (and thank you, Tom!)
On the good side scooters might avoid a speeding ticket! LOL. Cool video. Mahalo.
Soooooo true! 🤣
As others have commented, UK regulations read "An allowance of 10% + 3 Mph" that's why EVERYONE on a motorway is driving at 80 MPH in a 70 zone, based on their GPS Sat Nav speed!
Excellent video, Thanks! Car makers will tell you the speedometer will not always be correct. Lots of things can effect the speed, tire pressure, temp, time of day, atmospheric pressure, how long the bikes were on the road before the test due to tires heating up, condition of the tires and more. Because the vehicle makers know this they choose to set the speedometers a tiny bit lower just to err on the side of caution. I like to bring a phone with GPS speedometer app to double check my speed.
I had no idea! And good idea on double checking with GPS! I don’t have my phone on the holder often, so I hadn’t noticed.
I've known that most scooters indicate generously but I thought it was more a percentage thing🤷♀️. I've noticed that my Hondas run the most true 😉
I wondered about that. The AK is more of a higher end scooter & in line with what we saw on the cars. Honda, Yamaha & Suzuki have me curious in particular… I was totally surprised that for the cost, I couldn’t consider the Vespa more reliable!
@@ScooterNewbie 40 years of fixing mostly European cars for a living and owning 3 Italian motorcycles and several European cars taught me that being European and being expensive have nothing to do with reliability.
Is there any way to fix the Buddy speedometer?
Awesome video I will be giving her some more throttle when vehicles are behind me.
This is very common both on bikes and cars. The tires alone play a big part in this. And I dont mind it since its better than the other way around, because you know that you NEVER exceed the speed limit if you check the speedometer. Can save you some money. If you want a true reading use the GPS.😎
They are putting one outside our neighborhood, now I’m wondering what I can match!
I use my phone for GPS with speedometer reading.
Also the faster you go the more they will be off.. Iv checked this using the GPS app off my phone.. The only brand that seems to be
the most accurate with their speedometer's is Honda, the Chinese made scooters seem to be the most inaccurate..
A former Vespa store manager told me that all Italian bikes are off by 10% optimistic. So that means that, if I’m blasting down the freeway on my Vespa GTV300 at 70mph indicated, I’m really doing only 63mph, even though it feels like 80mph.
This sound right. My 2022 Sei Giorni read anywhere from 5 to 7 miles over. I checked it from the radar in my neighborhood.
I have a sym 400i. The faster you go the more the speedo was out. I could not understand why cars was driving right up behind me and overtaking when I was at the correct speed limit? Until I fitted a garmen onto the bike. I think the speed inaccuracy made riding dangerous.
My first scooter was a cheapo Wildfire 125 (advertised as a 150 but it was a 125). I expected the speedo to be way off but it was actually dead accurate. My second scooter was a cheapo Chinese 250 and the speedo was hilariously optimistic, it read about 15 mph high at a true 55-60 mph cruise speed. I thought my new Kymco Like 150 was probably reading high, but I just got a GPS speedo to compare and apparently it's only about 1mph fast at 40-50 mph, better than my car. Usually speedos are off by a percentage though, not a fixed number of mph, so the error will be greater at higher speeds. In general, motorcycle and scooter speedos have always read high. I remember reading many road tests in motorcycle magazines years ago where the speedos were almost always reading way higher than the actual measured speed. Newer speedos tend to be more accurate, especially the ones that are electronic. I'm not sure if I really trust those roadside radar speed things, though. There are 3 of them within a few miles of me and I can go out and drive through all 3 of them at the same speedo reading and get different radar readings, like 3-4 mph difference. This applies to my scooter and my car. I wonder how often those things are re-calibrated?
Rene are you still riding? Looks like you havent posted anything in a while . Maybe make an accessory video ? Maybe you got a new scooter present for Christmas? Cheers
The speedometer are not wrong because of a malfunction. In Europe manufacturers can be held liable for speeding tickets etc if it can be proven that the speedometer is underestimating the speed. As a result all manufacturers build in a fudge factor of approximately 4 km/hr to cover their buts.
All my motorcycles were accurate within half a mile low. (GPS) My analog gauges were lower in the high ranges. I was told manufacturers do this so claims to sue them for speeding tickets was refutable.
I have a 2021 genuine roughhouse. My speedometer says 50 mph my GPS says 45.
I don’t know why I never paid attention to the GPS speed really. 😆 🤷♀️
Are there phone apps to indicate speed based on GPS?
Google Maps does this.
That's was a lot of work, but fun lol. You know you can use a gps speed tracking system or in your cellphone with the app.
The fun factor, though! lol I've lost & almost lost my phone too many times now., so what phone holder do you use?
The phone mount i use is tackform brand. Is a little bit expensive but i never had problems with it. Even went i go off road trails with my adventure bike, the phone stays in place.
All my scooters and motorcycles were off by about 10% vs GPS speed until I got some that had digital speedos, then suddenly they were all within 1 MPH.
Edit: Except for a chinese Tao Tao 50cc scooter that was off by 30%!
Take the washer out of the variator. It limits speed
I'll look into this. This newbie hasn't heard of that before!
My Bintelli Sprint is 7 mph slower then indicated.
Whoa! Bigger gap than I would have guessed!
@@ScooterNewbie yes.
