Information on product safety

Report error

Gearshift cross - DEXTER RACING, reinforced - Vespa PX old gearbox (up to approx. 1983) / Rally / Sprint / GTR / TS 125

Reinforced shift cross for the PX old gearbox generation and the classic largeframe gearboxes. Developed for long service life and clean power connections - ideal as a preventive replacement or when gears jump out under load.

PX old gearbox Rally / Sprint / GTR / TS Reinforced quality Wear part

Why replace?

Gears jumping out under load / short loss of traction → typical gearshift wear pattern

Shifts precisely between the gears and establishes the frictional connection

Protects the gears and gearshift cog - timely replacement prevents consequential damage

Reinforced material for tuned engines and sporty driving style

Service & service life

Recommended replacement interval: 12,000-25,000 km (depending on performance/driving style)

For heavily tuned engines: check more frequently (use oil change interval)

Also change/check: Shift detent, shift rod, gears (burr formation), spacing

Clean shift cable adjustment prevents incorrect contacts and premature wear

Compatible vehicle models (PX old / classic Largeframe gearbox)

Installation instructions

Check gears for burrs, deburr slightly if necessary and distance correctly

Adjust the shift detent (play), shift rod (straight running) and shift cables precisely

Set the clutch cable play correctly - avoids load peaks when shifting

Transmission oil change recommended after the first 100-200 km of running-in

Note on wear

Frequent symptoms: Gear jumps under load / "jerks" → Check gearshift cross

Continuing to drive with a heavily worn cross damages the gears & shift detent

For tuned engines: Shorten the inspection interval

FAQ - Frequently asked questions about the DEXTER RACING gear cross (PX old)

How can I tell if I have an old PX gearbox?

The safest way is to check the chassis number/model year (see list above). PX old up to approx. 1983/84, after that mostly Arcobaleno/Lusso. Also a good hint: Remove the gearshift lever and check the width across flats of the shift bolt: SW13 = PX old, SW17 = PX Lusso. If unsure: compare the existing gearshift cross with the new part.
