2011 Vespa GTS 300 Overview
The 2011 Vespa GTS 300 is a scooter motorcycle built around 278 cc of displacement. Under the tank sits a Single cylinder, four-stroke engine running SOHC valve actuation. The bore and stroke measures 75 x 63 mm. 2011 Vespa GTS 300 delivers 22.30 Nm @ 5000 of torque. The factory-quoted top speed stands at 128.8 km/h, making it a capable performer in its class. From a practical standpoint, the 2011 GTS 300 tips the scales at 158 kg, carries a 9.20-litre fuel tank and offers a seat height of 790 mm. That's roughly 39.7 kg lighter than the average scooter motorcycle in our database.

2011 GTS 300 - 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 means no chain to clean, lube or adjust - meaningfully less routine maintenance than a chain-driven equivalent.
Considerations
-
⛽
Modest fuel capacity: The 9.20-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.
Valve clearance checks
SOHC valve actuation on the GTS 300 means clearances should be checked at the manufacturer's specified interval - they can tighten as mileage accumulates, and a light top-end tick is usually the first sign.
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 GTS 300 runs Single-sided trailing arm with 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.
GTS 300 - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2011 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.
Valve clearance service
Check that valve clearances have been adjusted at the correct intervals on any used GTS 300. A bike with clearances out of spec doesn't always feel obviously wrong - but tight clearances accelerate valve seat wear. Ask for service documentation proving it's been done.
