So I just got my brand new 75th Anniversary GTS 300. She's a beauty. I have previously only owned an LX150. While riding it for the first time I noticed that heat was coming out from the right handlebar/throttle area. I know that the cooling fan is just below this and it did come on often when I was riding. Understandable as it was in the high 80's F.

Is this normal? Just a little leak of heated air coming up through the front of the scooter? Or should it be sealed in such a way that it doesn't do that? Just curious what other GTS owners have experienced.

I imagine this will be a welcome thing come winter if it is normal.

Happy Days indeed!

May want to give a quick check of your coolant level if you're hearing the fan that often. It's easy to do.

Enjoy that scoot!

In cold weather it can come in handy.

Both the right and left side have a small radiator behind the glovebox.
There is a fan on the radiator on the left side, none on the right.
There are about 12 hose clamps working a radiator and 4 way junction under the right side. There is a post somewhere here where I posted pics of what is behind tht panel.

So,
1) check your fluid level and watch your heat gauge. if it is okay then
2) smell for that sickly sweet smell of antifreeze.

If you are not leaking, not smelling antifreeze, not overheating and fluid levels are good, then the heat you are feeling is probably nothing.

My radiator fan cycles on at just before the 3/4 mark, and brings it down to a little over the half mark. Since your highs are in the 80's, I would definitely expect some fan cycling at traffic lights and stops.

I have much more heat coming from the right side handlebar than the left side. Never uncomfortable but certainly noticeable.

This is because there is only one side of the fan.
To maintain the thin line of the front shield there are two radiators connected between each other and the (small) fan cools on one side only.
Generally, many modern Vespa enthusiasts from the 200 version upwards do not like this choice ... in very hot places the fan is almost always on and the hot air ends up on the right leg; it is not pleasant.

Thank you. Just wanted to make sure it wasn't a defect in my new baby. That fan is hella loud but I'd rather have the engine cooling than not.

Surely the fan is on the left side? Or has that changed for the newer GTSs? And the air outlets are at the sides...

Why? When was it on the right side? It was always on the left, starting from the GT200...
