Hello!

I am my first year of Vespa driving and here it starts to become a bit cold. It will be soon 4-10 degrees most of the time.

I have questions about Vespa performance in regards to that. I have Primavera 50 cc 2018 4t 3v. Does cold weather have effect on my Vespa power? Because it slightly feels it is driving a bit slower. I have a new Vespa with 4500 km on the odometer, derestricted with original engine, Malossi multivar variator. It went around 62km/h during summer only with derestricted CDU, but now I have Multivar too, and it is still around 62km/h, though slightly better pull.

Does cold weather and letting Vespa sit around in wet weather for a while has effect on performance? Should I put it away asap?

Some beginner questions here, thanks if anyone cares to help.

Best wishes
Andre

Hard to say as I've never owned a smalie. But I will say that I've ridden my kitted GTV300 in up to -15C and have had no issues. It's is stored indoors but I have left it parked outside for 8 hours or so in cold damp weather and it's fine. The battery is the biggest concern in cold. TBH I would think once the engine warm up it should be fine. I can definitely feel warm air blowing off the radiator even in extremely cold weather which means the engine isn't cold. If course I imagine the motors may be pretty different on the modern large frame models.

good, bad
Probaly need to check your tire pressures when it gets that cold, as they may be somewhat low. Generally oils and greases get thicker in the cold, so that may add some drag. On the other hand, the colder, denser air usually allows the engine to make a little bit more power. My SH150 top speed seems to go up a couple of MPH when the temp gets down around freezing.

Smaller displacement engines actually make more power with cold dense air. They'll just be a little more fussy until they warm up to operating temperature. Do cover the machine the best you can when you're not using it. The bodywork and the switchgear don't like being left out in the wet weather.

Thanks guys for the replies. Maybe the Vespa is slightly slower than some videos with same setup because it has 4500 km on odometer then. I thought it could have been cold weather. Tire pressure also has effect on the spidometer, right? I need to check it next time.

About covering. I am really afraid since Vespa tipped over when I had the cover and wind was high. So I have not covered it at all, and kept it out. Last month or two it has been pretty rainy though. I still want to use it but maybe I need to have her get some dry conditions.

When they start putting salt on the streets I really need to flee with the Vespa though as it probably starts ruining stuff underneath.

Thanks again for replies!
