I have a new 2015 300cc ABS Vespa. First scooter for me...many motorcycles for many years. Very pleased with the bike and the superb Marietta, GA dealer.

When I advance the throttle, the bike accelerates briskly. Sometimes, at certain rpms, I detect a sound...sort of a vibration, that passes as soon as I change the throttle just a bit. Once I am at my desired speed, the sound goes away. I am not used to an automatic transmission so please tell me if the sound that I am hearing is normal transmission sound. Thank you.

There are various mechanical noises, for sure. I think it's impossible to tell by your generic description. Your dealer should be able to tell you. As your bike is under warranty (for two years, I believe), I wouldn't worry about it now. My recommendation is to get used to the bike, the sounds, the handling, the ride.

The description is a tad vague, but I had a vibration sound on my GT200 at specific rpms, it turned out that the little heat shield on the exhaust down near the footboards had a loose screw, worth ensuring no rust has affected it, screws are totally tight just a possible simple solution.

Welcome to MV. You should love North GA on that scooter.

Welcome to the Forum from a fellow Metro Atlantan!

I bought a 2015 GTS from Vespa Marietta as well. I'm not experiencing anything I'd consider abnormal; can you provide more info? Is it a vibration noise, or a buzz through the seat/floorboard/handlebars?

There is some vibration that's endemic to a single cylinder engine...if you're accustomed to the silky smoothness of a multi-cylinder motorcycle, the scooter will definitely feel different.

Also...pics are encouraged!

I love my MP3-500, but it does run rough in many ways. I'm well aware that there is a difference, but they are still single cylinder, liquid-cooled, CVT systems from the same maker. One noise and vibration I regularly feel is when I roll off the accelerator and then get back on. It feels like the belt rattling around until it finds its groove again. Perhaps this is what you are feeling?

Yes, there definitely is a difference. The 250/300 Quasar engine is a very smooth and quiet running design. The 400/460/500 Master engine is somewhat more "agricultural" in it's characteristics.

Fair enough, but might the CVT still be the cause of the vibration? Having said that, you could tell me that the Master engine was used in pneumatic drills by the dinosaurs and I would believe you.

Thank you all
David in the UK described accurately the noise that I was hearing. I appreciate all the responses.

The dealer took a look at it and found a very slightly loose rear shock mount. It was raining out so he did not take it for a test ride. The dealer suggests that my unfamiliarity with scooters may contribute to my not yet fully understanding the noises that I am concerned with.

I will get it into the shop next week and the dealer will take another look.

I was right for once!

I hope that the shock mount tightening makes things better - not only because it's good for you, but the universe might just survive the shock of me being right if it turns out to be for the wrong reason...

Great Vespa Forum
Orangezorki,

You guys are great. It is the knowledge experience
we consistently get out of MV. The forum successfully
diagnosed the improperly installed water pump gasket
on my 300.

Unusual vibration sound - loose screw/loose something.

Another case solved Sherlock!

New owner question.
My GTS 300 had a a slight vibration at around 45 - 50 when running in. It is vibe free now with 3K on the clock. Following a number of years on multi cylinder bikes such as the 600 Fazer, I enjoy the unstressed nature of this machine. Even at motorway speeds, the Vespa is not reving a lot. I do miss the acceleration of a bike, but now in my sixties, I love the chilled ride and practicality of the GTS. In reality, I find myself riding at the same speeds I was riding the bikes lately. Most of my journeys are on B roads, and for recreation. An indicated 80+ is easily accessible at which speed, the Vespa feels supersonic! No regrets.
