So far it seems I am getting about 55 ish mpg on my Vespa GTS super 300 tech. When I fill up it says 110 miles till my next fill up and I recall it was that same number when I bought it from the dealership. This is also with no accessories since I haven't had time to get the accessories shipped in to put on. Also I forgot to check on how many gallons I filled on my first fill up stupidly. Am I doing something wrong? I notice my overall mpg is 61 (assuming the Ø means average mpg) Also does anyone know how I can see how many miles till my next service appointment? I remember it used to appear on the screen but I'm not seeing it anymore?


110 miles


61 mpg

Not a 2023 but my 2018 GTS 300 seems to get 55mpg,
every tank, no matter how I ride it, but mostly it gets ridden 2 up (300lbs total), on and off WOT, on fast hilly suburban, coastal, and canyon roads.

The 2015 Sprint 150 mostly 1 up, similar riding, always around 80mpg

I'd expect using the joystick up/down you'll get the odometer. compare it to the service table in the manual.

Greetings. My Vespa GTS 300 with HPE got close to 70 MPG. I got it the first year the HPE engine was introduced in the US. I replaced it with a BV400 last October and it gets around 60 - 65 MPG. So I think your mileage should be a lot better.

Yeah no matter how I drive I'm still getting 61 mpg but I looked it up and I heard that's about an average mpg for a gts. I hope it doesn't get too much worse after I add all the protection bars on it and top case :S

X mpg means next to nothing without the context of mph and topography. Scooters and motorcycles, in my experience, have linear fuel consumption: the faster you go, the faster you go through your fuel.

It wasn't an HPE, but my GTS averaged ~60mpg. The spread was 45-70mpg...45 if I was going WOT on the interstate and 70 if I came down out of the mountains and stayed off of highways.

As the engine breaks in, it levels out for a given type of riding. Just remember to keep an eye on the oil level! New bikes, especially HPE's as I understand it, use oil for the first few hundred to thousand miles.

Ive been getting a solid 68+ miles per gallon. The Verde Green GTS I have gets over 80 and the fill-ups make sense of the numbers.

I can't complain no matter what I ride though, anything over 60 MPG is excellent! It all depends on so many factors though so I wouldn't worry about it.

When you get close to your first service, you will see the flashing wrench icon on your display, it doesn't let you miss the service intervals

And I find that I get the worst handling at the without passenger settings. In fact the only time I've ever gotten the dreaded Vespa wobble was with the front tire under 28psi. I find handling and mpg is best at 30 and 34-35. Your experience might be different.

I averages 74mpg on my 2018 GTS after it was properly broken in around 2,500-3,000 miles. I haven't even bothered to check on my new 2023 as it is just now in for its first service. Im. I'm not sure if I will check until I get a couple thousand miles on it.

Ok cool I will try 30psi in the front and 34psi rear and hopefully that'll fix my mpg problem 🤞also side note I only have 200 miles on my 2023 gts so far

I wouldn't worry about it at this stage. On my 2018 I initially was getting in the 50s but over 70 after 3,000 miles. That's one reason I haven't bothered checking on my 2023.

How come the tires on my gts says front 38 psi and rear 45 psi cold? That's way higher than what I heard was recommended. Also how do I recalibrate the asr?

those pressures sound like they are MAX, not recommended.

ASR recalibration is described in the User Manual.

Yeah I just read the manual. the recalibration process is long and complicated and it says only do it when you replace the tires. Since I have not replaced the tires yet I don't think I will try to recalibrate the asr yet. 😅

According to owners manual (cold):
Front: 1.8 bar = 26.11psi
Rear: 1.8 bar (single) = 26.11psi / 2.0 bar (with pillon) = 29.0psi

I would go with (cold):
Front: 2.0bar = 29.0psi
Rear: 2.2bar = 31.9psi (regardless single/pillon)

"PROCEDURE FOR CALIBRATING THE ASR SYSTEM after replacing one or both tires.

After turning the ignition switch to the "ON" position, the ABS indicator light and the ASR symbol "2" will flash at the same frequency (fast flashing).

1. Start the vehicle, drive a short distance at more than 5 km/h (3 mph) and wait until the ABS indicator light and the ABS symbol stop flashing.

2. Stop the vehicle and allow the engine to idle for at least 3 seconds.

3. Turn off the ASR system by pressing the corresponding button "1" on the handlebars and check that the ASR deactivation symbol "2" is solidly lit.

4. simultaneously press the engine starter switch and the ASR deactivation/activation button "1" for at least 4 seconds (it does not matter if the left brake lever is pressed).

5. the activation of the operation is confirmed by the ASR "2" symbol lighting up with slow flashing (1 flash every 2 seconds).

6. accelerate to a constant speed of 30 km/h (18.7 mph) and hold it for at least 10 seconds.

7. the end of the procedure is indicated by the ASR symbol "2" going out.

8. After the procedure is completed, turn the ignition switch to "OFF" and wait at least 30 seconds before turning it to "ON" again.

9. If the procedure is not completed within 2 minutes, the ASR symbol "2" will remain solidly illuminated and the ASR will remain deactivated until the ignition switch is turned back to "OFF".

10. To re-enable ASR, the ignition switch must be turned "ON" and the procedure repeated until successful."

it's not hard. and not that long once you are familiar with it

the manuals comment about tire change is really a minimum interval of recalibration. it doesn't use the word 'only'

changing the pressure as much as you intend will have enough effect on the circumference that I strongly recommend it.

ASR works on detecting / matching the speeds of the front and rear wheels. This has to do, among other things, with the rolling circumference... if you change the air pressure, you also change the rolling circumference...

Tire tolerance vs vehicle design. I'm gonna switch bikes for a clearer example...at least, this is when it really clicked for me.

My BMW G310GS uses a 19" front tire and a 17" rear...exact same tire specs as its bigger sibling, the F750GS. The baby GS weighs roughly 380lbs (~172kg) and calls for 25/28psi front/rear. The middle GS weighs 493lbs (227kg) and calls for 32/42psi front/rear. My Triumph water-cooled Bonnie (~500lbs) uses the same rear tire but at 36psi.

Lower pressure means the tire can flex a little more on lighter bikes so it can get the proper amount of traction from less weight.

Just gotta look more closely. Do they actually say "INFLATE TO 38 PSI"

or do they say "INFLATE TO MAXIMUM 38 PSI"

You have all your answers before you even ask your questions, have some confidence in yourself and you'll find em!

8. After the procedure is completed, turn the ignition switch to "OFF" and wait at least 30 seconds before turning it to "ON" again.

9. If the procedure is not completed within 2 minutes, the ASR symbol "2" will remain solidly illuminated and the ASR will remain deactivated until the ignition switch is turned back to "OFF".

10. To re-enable ASR, the ignition switch must be turned "ON" and the procedure repeated until successful."
Ok I think I did it! I didn't see any ASR symbol after I was done and thought I had done something wrong until I read this! Thanks for all the invaluable help!
