Dexter Racing visits the Open Day

DEXTER Racing - Racing technology from Trentino

Anyone who is out and about in the classic Vespa scene will sooner or later stumble across DEXTER Racing - and get stuck. Not because of big words, but because of parts that work on the track as well as in everyday life. Behind the name is Luca Moscon from Mezzolombardo (South Tyrol): Engineer, developer and driver all in one. In his workshop deep in Trentino, he does not build off-the-peg tuning parts with DEXTER Racing. His workshop produces heavy-duty racing components - developed on the test bench and verified on the track. And with success: at the 24-hour endurance race in Whilton Mill, Luca drove the competition into the ground in 2025.

Workshop instead of showroom

At Luca, CNC milling machines are whirring, chips are flying and test benches are running. The machine park is exceptionally broad for a one-man factory - and this is precisely the reason for the vertical range of manufacture that is so rare today: from the raw part to the finished component, almost everything is in-house.

Fan wheels, exhaust systems, brake arms or transmission parts - all designed for maximum continuous load and tested for real racing applications. Many parts come directly from the "Vespa Proto" project, where they were tested under extreme conditions. The installation of DEXTER Racing components is always uncomplicated and requires little processing.

Luca Moscon in the Scooter Center - Test bench run in the video

DEXTER Racing boss Luca Moscon visited us at the Open Day. Fresh from the Pomposa race track, where he had just torn off 500 kilometers. He brought what he calls his "unwashed" racing scooter with him and placed it on our test bench. You can see the results in the video below:

All this is in Luca's scooter

• Engine housing: Dexter
• Cylinder: SuperNova 180 with exhaust valve (64x56.7)
• Exhaust: Dexter
• Carburetor: VHSB38
• Crankshaft: Dexter BIG, diameter 94 mm, width 45 mm, stroke 56.7 mm, connecting rod 110 mm, with polygonal toothed pinion mount
• Gearbox: Dexter Endurance, module with coarse teeth, 5 mm wider than the original, 6-arm shift claw and the first with top idle. Special gear ratio for racetrack use: a longer first gear (even longer than an original second gear), an intermediate second, short third and short fourth. This allows slow bends to be taken in first gear without any problems.

Everything was made in Luca's workshop.

About the name "Dexter"

If you've been wondering where the name Dexter comes from: friends gave Luca this nickname early on. Why? The whole thing is based on Dexter's Lab - an animated series from the 1990s. The series is about Dexter, a highly intelligent boy who runs a huge secret laboratory in his parents' house. Of course, his parents are not allowed to know anything about the lab, which is bigger on the inside than the house.

When it comes to Vespa technology, Luca has actually come surprisingly close to his namesake: A lot of brains, a lot of laboratory - and in the end, parts that simply work: DEXTER Racing.
