2005 PX 150 - Pros & Cons

Strengths

Strong front braking: The single disc front brake gives excellent stopping power and responds well to aftermarket braided lines.

Considerations

Drum rear brake: The drum rear brake is adequate but lacks the modulation and fade resistance of a disc setup found on more modern equivalents.
Modest fuel capacity: The 8-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.

Wear Points & Servicing Notes

Brake disc and pad wear

The single disc front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.

Suspension condition on used examples

Up front, the PX 150 runs Oscillating arm, coil spring and dual effect hydraulic shock absorber and Hydraulic shock absorber, 88 mm stroke at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.

Frame & chassis check

The frame is Pressed steel monocoque - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.

Low-speed handling

At just 116 kg, the PX 150 is light enough to manhandle easily at a standstill - one of the practical advantages of its class.

PX 150 - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2005 Vespa PX 150 with its 151 cc scooter, start with the basics: check the service book for oil change frequency, inspect the drivetrain for wear, and look for oil seepage around the engine casings and rocker covers. Now 21 years old, this scooter is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. A cold start test is invaluable - a well-maintained PX 150 should fire up cleanly and settle to a smooth idle within a few seconds.

Oil and filter changes

Regular oil changes are the single most important maintenance task for the PX 150's 151 cc single cylinder. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.
