FRT EVO3 Reinforced Clutch Cover – Vespa Smallframe, Black
The FRT EVO3 clutch cover is a thoroughly reinforced solution for high-performance Vespa Smallframe clutches. The housing is made of heat-treated G-AlSi7 aluminum, features a precision rack-and-pinion mechanism, and, with a clutch chamber diameter of 118 mm, offers plenty of space for modern aftermarket clutches.
The case-hardened and ground release shaft (Ø10 mm) is mounted on dual bearings. Combined with an O-ring seal and a self-lubricating bushing, this creates a very stable release system that truly shines when dealing with high clutch forces.

Rack-and-pinion mechanism: precise and smooth clutch actuation
118 mm inner diameter: designed for virtually all common small-frame tuning clutches
Ø10-mm release shaft: case-hardened and ground
Dual-bearing design: stable guidance even under high spring forces
Pre-assembled: delivered fully assembled
Rack-and-pinion mechanism instead of simple lever operation
The EVO3 design utilizes a rack-and-pinion mechanism. This ensures that the movement of the clutch arm is precisely transmitted to the release system.
Especially for clutches with high spring force, guidance that is as play-free and precise as possible is crucial. The rack-and-pinion mechanism reduces unnecessary tilting movements and ensures direct, repeatable actuation.
Ø118 mm clutch housing – for modern aftermarket clutches
The interior space for the clutch basket measures Ø118 mm. According to FRT, this makes the cover compatible with standard small-frame clutches on the market, specifically including models from Fabbri, Falc, EGIG, VMC, and Crimaz.
The area for the primary sprocket has a diameter of 26 mm.
Ample installation space for high-performance clutches
Clutch mounting: Ø118 mm
Sprocket mounting: Ø26 mm
Compatibility: Fabbri, Falc, EGIG, VMC, Crimaz, and other standard market clutches according to FRT
Ø10 mm release shaft—hardened, ground, and double-bearing
The release shaft has a diameter of 10 mm and a usable length of 107 mm. It is case-hardened and then ground.
This results in wear-resistant and precise bearing surfaces. The double-bearing configuration further stabilizes the shaft and reduces the tendency to tilt under high loads.

Compatible with the PK XL2 and many classic small-frame models
The FRT EVO3 is primarily designed for the Vespa PK XL2, but can also be used on other small-frame models:
Vespa V50
Vespa PV / Primavera
Vespa ET3
Vespa PK XL
Vespa ETS
Note for V50 / Special / ET3
According to FRT, when used with the brake anchor plate or brake base plate from the Vespa Special or ET3, the clutch cover must be machined. The relevant area must be ground down to ensure sufficient clearance.
G-AlSi7 aluminum – heat-treated and glass bead blasted
The housing is made of G-AlSi7 aluminum and heat-treated. The surface is then blasted with glass microbeads, resulting in a technically clean and uniform surface.
The version offered here is black.
Fully pre-assembled
Delivered ready for installation
According to the manufacturer, the FRT EVO3 clutch cover is delivered fully assembled. The release shaft, bearings, bushing, seals, and pressure plate are thus already assembled as a coordinated system.

Installation Instructions
Check the clutch and clutch cover for full freedom of movement before final installation
For V50/Special/ET3 models with the corresponding brake anchor plate, grind the cover to the correct clearance according to the FRT
Route the clutch cable neatly and without tension
Adjust the clutch play correctly after installation
After the first few rides, check the operation and cable play
