2011 GTS 300 Super - Pros & Cons
Strengths
-
🔧
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
-
⚙️
Low-maintenance final drive: Running Belt final drive cuts out the regular chain cleaning and tensioning that most bikes need.
Considerations
-
⛽
Modest fuel capacity: Range between stops is limited by the 9.20-litre tank - plan fuel stops accordingly on longer routes.
Wear Points & Servicing Notes
Fuelling & injector care
The fuel injection on the GTS 300 Super needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.
Valve clearance checks
With SOHC valve gear, the GTS 300 Super needs periodic clearance checks; caught early they're a cheap adjustment, left unchecked they accelerate valve seat wear.
Brake disc and pad wear
Braking up front comes from Single disc - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.
Suspension condition on used examples
The GTS 300 Super's suspension runs Single-sided trailing arm with dual chamber hydraulic shock absorber with coaxial spring at the front. The rear uses Two dual effect shock absorbers with adjustable preload. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The GTS 300 Super runs belt final drive: no lubrication or frequent adjustment like a chain, though belt tension and wear are worth a periodic look.
GTS 300 Super - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2011 Vespa GTS 300 Super, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy GTS 300 Super should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects a GTS 300 Super's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Fuel system care
Fuel injection on the GTS 300 Super needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
Valve clearance service
Valve clearances are easy to overlook on a used GTS 300 Super since a bike out of spec doesn't always feel obviously wrong - but the wear it causes is real. Ask the seller for documentation before assuming it's been done.
