Did you convert your Vespa before 2026? Then stop right here, because this upgrade was designed exactly for you.
You already know how much fun it is to ride through the city with the throttle wide open in electric silence. But there is still untapped potential under that bodywork. From today you can leave the belt drive behind and fit the exact same mechanics as our SPORT kit: three hardened steel gears.
This is not a software tweak. It is a real mechanical upgrade: we open the casing, remove the belt and install the new transmission assembly.
0 to 50 km/h in 4 seconds
A belt is flexible by nature, so it creates friction and an elastic effect. Switching to the rigidity of steel eliminates that loss completely: peak torque reaches the wheel instantly.
Acceleration off the line becomes immediate, with a 20% torque increase and 0 to 50 km/h in 4 seconds. You feel the difference most when you ride two up or tackle a steep climb.
15 km/h more top speed
Power delivery becomes smoother and unlocks the true potential of the motor, giving you 15 km/h more top speed. A reserve of power that changes everything on faster roads outside town.
Zero maintenance and a brand new sound
The first thing you notice when you get back in the saddle is the voice of your Vespa. The sound becomes softer, fuller, more refined.
But the difference that really counts every single day is another one: the gear assembly is sealed and robust. No more tension checks, no more periodic belt replacement. Turn the key and go.
How to get the upgrade in a few clicks
You can now handle everything yourself through the new Retrokit online store. Order the upgrade online and ship your kit to our workshop in Rimini. The video below shows you how.
