Owner Experiences & Common Issues
Throttle response and fuelling
The fuel injection on the 2023 Vespa GTS 300 is generally well-regarded.

A quick visual check of the injector connectors during routine servicing is good practice on higher-mileage examples.
GTS 300 - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2023 Vespa GTS 300, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained GTS 300 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 on any GTS 300. 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.
Fuel system care
The GTS 300's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
