Hi there, I have about 60 miles on my new Supertech and it's making a loud whining noise coming from the front behind the horn cover. It almost sounds like a loud over working computer fan. Anyone else having this issue?

It's the fan. No worries.

Should I be worried about the heat coming from inside the dash?

No. A GTS is water cooled, with the radiator and fan in the leg shield behind the front wheel. There are vents in the side of the leg shield to let the heat out.

The fan often comes on when the scooter is idling and not moving. That's normal operation.

You should read your owners manual. There's lots of stuff in there about checking oil and coolant levels, tire pressure, brakes, etc. that's important for your safety and the long life of your scooter.

Ride safe & have fun! 8)

The fan can be on moving or stationary. It should not be on all the time. It cycles on and off with the temperature of the coolant.

I am not knowledgeable on the Supertech. There maybe a cooling fan associated with the the high tech dash board.

In reality the fan shouldn't be coming on very much unless it's a very hot day and you are in a lot of traffic going slowly. MAKE SURE TO CHECK YOUR ENGINE COOLANT LEVEL.

The coolant level of course should be ok if the dealer has checked it correctly during the pre-delivery inspection. But I've had several new bikes come in with low coolant causing the bike's fan to operate too much. This can be bad for the engine if the level is low for a long length of time.

Check your owners manual to see how to check the level. It's important.

+1 - read the manual and check the coolant level. And my 2015 uses a very specific coolant (Eni) per Piaggio's recommendation... I try to fill it only with that coolant, but one shop used Motul which seemed to work fine.

Yes, any OAT based Ethylene Glycol based coolant meeting the specs laid down in the owners manual will work fine. I think the ENi is hard to get in lots of places.

I see you live in AZ. Your cooling fan will come on a bunch. I live in FL. I hate the cooling fan in the summer. I ride my Monkey mostly in the summer. I wish I could fabricate a scoop to aim the hot air off of my legs. However, it's great in the winter!

Good point about the OP living in Arizona. My fan comes on all the time in the summer when it's 95 degrees Fahrenheit and it's not moving (i.e. a drive-thru window or a very long traffic light). Since the weather cooled down in Connecticut, it really hasn't come on at all, except for when I let it idle for 10 minutes after a coolant change (intentionally to test that it would come on).

Just a point on the operating temperature of the Supertech - compared to all my previous GTs(3) and GTSs(2) it runs a lot hotter so I wouldn't be too surprised on the fan coming on more frequently either.

its very noticeable when the radiator fan turns on. its REALLY loud. scared me the first time too. if its hot, or youre in start and stop traffic without air flowing into the vent to cool it, it will turn on... then it should turn it self off after a few minutes..

anyone know if theres a way to make the fan quieter? its almost like embarrassingly loud, lol...

So when you watch the video, do you think that sounds about right?

Hi guys,

Sorry for bumping an older thread. I am a soon-to-be Vespa owner living in Vietnam. Great country and very, very cheap.

. . . . .

I am searching for a new / used Super Tech and came across this bike.

https://www.youtube.com/watch?v=98MudtlyPtM

I live in Vietnam and I know that the fan makes noise to cool the bike, but in this walkaround (obviously, I will go see the bike if all is good) the fan sounds VERY noisy to me.

It does get hot here, it was 34 C (93 F) and the bike was idle, not after a hot run.

What do you guys think? Am I being overly critical?

Ah thanks, man. The wife will hate that. I guess I will be going for the GTS 150 ... unless that has another problem.

Which, of course, you don't get the chance to experience we Nor'Easterners do.

There are those weird circumstances when one might experience the fan coming on briefly: a few weeks back, I was stuck in the usual late-morning stop-and-go on the Brooklyn-Queens Expressway, and the fan came on twice, albeit briefly, even though the air temperature was in the low-50s (F). (This was just after the bike had her major makeover, including fluids.)
