I just got my 2016 PCX last night...
Everything feels good except when I speed up where I can hear the rattling noise from engine.
After reaching around 50-60 km/h, the rattling seems to disappear and the entire scooter sounds very smoothe...
Is it normal for PCX, do you guys have the similar experience?
Thanks.

Re: New PCX Acceleration Noise
If I recall over my membership time I've seen a few low severity rattles diagnosed in here as the following, and perhaps others can recall more possibilities.
Deceleration on a PCX makes a lot of vibration, so much so you can't mount a camera to the body.
1. Check the license plate. I placed wool fiber spacers between the plate and the mount to insure certain rpm's didn't start it vibrating.
2. There is a close connection up front between the stock windscreen and the body panel, (at the nose) put a buffer between these two items and ride out eliminating the easy fixes first.

Re: New PCX Acceleration Noise
Are you sure it's coming from the engine? You say it's across the range of normal commuting speeds (upto 50-60kmh) - I'd take it back to the dealers as it should not be like that from new.

my 2016 pcx150 makes the same noise. There seems to be a rattle at certain speeds. Is yours similar, it sounds like its a rod knock

Re: New PCX Acceleration Noise
It normal in the midrange..... it's a single cylinder, therefore there's always going to be some noise vibration and harshness (NVH).

Re: New PCX Acceleration Noise
Absolutely, Mike, it is the knocking sound as you described, which is more precise than rattling... it happens when I accelerate from 30-60km/h.Mike888 wrote:my 2016 pcx150 makes the same noise. There seems to be a rattle at certain speeds. Is yours similar, it sounds like its a rod knock
Just hope it will go away after break in, apart from this, PCX is great.
