2019 GTS 300 SuperSport - Pros & Cons

Strengths

Fuel injection: The fuel injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.
Low-maintenance final drive: Belt (final drive) final drive means no chain to clean, lube or adjust - meaningfully less routine maintenance than a chain-driven equivalent.

Considerations

Modest fuel capacity: The 8.50-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.

Wear Points & Servicing Notes

Fuelling & injector care

Fuelling comes from fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.

Brake disc and pad wear

The Single disc. ABS. Hydraulic. 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 GTS 300 SuperSport runs Single arm, dual chamber hydraulic shock absorber with coaxial spring and Two dual effect shock absorbers with adjustable preload 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.

Final drive maintenance

Final drive is by belt - lower maintenance than chain with no lubrication needed, but tension and tooth wear should still be checked at service intervals.

Frame & chassis check

The frame is Sheet steel shell with welded structural reinforcements - 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.

GTS 300 SuperSport - Buying & Maintenance Guide

What to check before buying

When inspecting a used 2019 Vespa GTS 300 SuperSport, 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 SuperSport 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 SuperSport. 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 SuperSport'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.
