Gearshift cross - DEXTER RACING, reinforced - Vespa PX Lusso/Arcobaleno (from approx. 1984), Motovespa Iris/EFL, LML Star/Stella, T5, Cosa

Reinforced shift cross for the Lusso/Arcobaleno gearbox generation(from ~1984) as well as corresponding licensed models from Motovespa (Iris/EFL), LML (Star/Stella) and the T5 and Cosa models. Designed for high mileage, precise traction and stable shifting behavior - ideal as a preventive change or if gears jump out under load.

PX Lusso/Arcobaleno Iris/EFL Star/Stella T5 / Cosa Reinforced quality Wear part

Why replace?

Gears jumping out / short loss of traction → typical wear symptom
Ensures precise frictional connection between gearwheel and shaft
Protects gears & shift detent - timely replacement prevents consequential damage
Reinforced for more powerful setups and sporty riding style

Service & service life

Guide value for replacement: 12,000-25,000 km; check earlier for tuning
Also check: Shift detent, shift rod, spacing, gears (edges/gears)
Precise shift cable adjustment reduces wear and false contacts

Compatible vehicle models (Lusso/EFL gearbox from ~1984)

TX/TX200 and other PX derivatives with EFL layout

Test criterion: Lusso/EFL gearbox (e.g. shift bolt SW17).

PX old (up to ~1983) - other cross required

Installation instructions

Check gears for edges/gears, distance correctly
Adjust the shift detent (play), shift rod (straight travel) and shift cables precisely
Set the clutch cable play correctly - avoids load peaks when shifting
Replace transmission oil after 100-200 km run-in

Note on wear

Symptoms: Gear jumps under load / "jerks" → Check gearshift cross
Continuing to drive with a heavily worn cross will damage the gears & shift detent
For tuning: Shorten the inspection interval

Tip: Keep the oil clean

BGM PRO magnetic drain plug (BGM9030): bundles microparticles/chips and keeps the transmission oil clean - ideal after gearshift clutch service.

FAQ - Frequently asked questions about the DEXTER RACING gear selector (PX Lusso/EFL)

The gearbox was revised from ~1984(Arcobaleno/Lusso). Practical tip: Shift bolt usually SW17 (PX old: SW13). Also check model/FIN (PX Arcobaleno, Iris/EFL, Star/Stella, T5, Cosa).
Depending on performance/driving style approx. 12,000-25,000 km. Check earlier for sporty setups and replace at the latest if gears jump out or edges are visibly beveled.
Gear wheels (edges/gears), spacing of the main shaft, shift detent (play), shift rod (straight running) and the shift cables (adjustment).
Yes, provided the gears use the Lusso/EFL profile. Always check the gear set and spacing and ensure that the contact surfaces of the gearshift cross are adequate.
Yes. T5 and Cosa use the same type of gearshift cross as the PX Lusso/EFL models.
