2023 Vespa GTS Super 300 Overview
Vespa GTS Super 300 is a scooter motorcycle, displacing 278.3 cc. Power comes from a Single cylinder, four-stroke engine running Single Overhead Cams (SOHC) valve actuation. Bore and stroke come in at 75 x 63 mm. On the performance side, it delivers 26 Nm @ 5250 Revolutions of torque. On the road, the 2023 GTS Super 300 tips the scales at 158 kg, carries a 8.50-litre fuel tank, offers a seat height of 790 mm and spans a 1380 mm wheelbase. That's roughly 39.7 kg lighter than the average scooter motorcycle in our database. The full 2023 Vespa GTS Super 300 spec sheet below covers every technical detail, from suspension travel to tyre sizes.
2023 GTS Super 300 - 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) 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 8.50-litre tank - plan fuel stops accordingly on longer routes.
Wear Points & Servicing Notes
Fuelling & injector care
The fuel injection on the GTS Super 300 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 Single Overhead Cams (SOHC) valve gear, the GTS Super 300 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. ABS. Hydraulic. - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.
Suspension condition on used examples
The GTS Super 300's suspension runs Single arm with helical spring and hydraulic shock absorber at the front. The rear uses Double hydraulic shock absorber with helical spring with preload adjustable in 4 positions. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The GTS Super 300 runs belt final drive: no lubrication or frequent adjustment like a chain, though belt tension and wear are worth a periodic look.
Frame & chassis check
Built around a Sheet steel shell with welded structural reinforcements, the GTS Super 300's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.
GTS Super 300 - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2023 Vespa GTS Super 300, 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 Super 300 should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects a GTS Super 300'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 Super 300 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 Super 300 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.
