Modern Vespa

Hi! I'm brand new here and wondering if I could get some suggestions….

I have a 2020 primavera 150 and am looking for suggestions on performance upgrades. I generally ride the surface streets around town. Taking off from stop lights is super quick 0-50ish), but the streets around me average 50 mph and people go a lot faster. I'm worried about the wear from going almost full throttle ALL the time and would like to try add some room to get out of the way of any cars coming at me.

I've added the variator kit. Eventually I want to do the 183 cylinder kit, but that needs to wait a while. Does anyone have any suggestions? I was looking at the Malossi Secondary Gear/ Overdrive. Is that worth it?

Thanks!

The upgrade kit will boost power so you'll get to 60 faster but won't add a lot of top speed. A small flyscreen helps a little too.
If you need to go 60 a lot of the time then a 300 is the answer. Might work out cheaper than all those upgrades too.

Welcome to MV

I've got a 125cc version of your engine. As long as they're serviced at the correct intervals, there's no worry about going full throttle with the engines. Most small displacement engines spend the majority of their life at high revs, and there's never really any talk on here about engine problems.

Some of the GTS 300's have a reputation for drinking oil, but the small capacity engines seem bulletproof.

Which variator did you add? Did you see a difference in top speed, or acceleration, or both?

The malossi overdrive kit is made to compliment their cylinder kit. I wouldn't go for it on its own. If the gearing is too long, you'll struggle and could potentially lose speed without the power it requires.

How much faster? Even a 300 HPE has limited headroom in fast traffic in most of the US since speed enforcement has disappeared in post Covid era. In Mad Max like traffic, I ride a sport bike to feel safer. Upgrades to the 150 are marginal at best. My 150 and 300 are mainly used around town.

the 190 kit will give you better take off and midrange, but not much more top speed. although you'll get there quickly.

with a stock cylinder the upgear isn't really worth it and will actually slow the acceleration down, but you'll gain some top speed, eventually, when you get there. without the kit you don't have enough power to take advantage of the longer legs of the gears.

As stated, the 300 is the best upgrade if you want more top end. I have a mostly stock Primavera 150 as well. It tops out at 67mph, indicated by GPS, full throttle. It cruises at 60 or so with no problems. That is enough for me, but not everyone. Its my experience that the upgrades only reduce reliability and give no more top end, but get you there faster. Attached is a photo showing my non performance upgrades. BTW removing the emissions was not to improve performance and it didnt. I had to vent the Gas Cap however. Wishing you the best.

What size is your rear tire? Will the same size fit in front?

No matter what you are driving, or how fast you are going, there will be some arsehole rage passing you.

Performance upgrades reduce the reliability & lifespan.

Being seen & not putting yourself in dangerous positions is far more effective
I worry more about being seen than trying to keep up with the fastest traffic.

Own your place on the road, if you leave room for people to cut you off they will. Ride on the left of the right lane & right side of the left lane.
