2017 Vespa GTS 300 Overview

Vespa GTS 300 is a scooter motorcycle. Power comes from a Single cylinder, four-stroke engine. Bore and stroke come in at 75 x 63 mm. On the performance side, it delivers 22.30 Nm @ 5000 Revolutions of torque. Top speed is factory-quoted at 128.8 km/h. On the road, the 2017 GTS 300 tips the scales at 158 kg, carries a 9.08-litre fuel tank, offers a seat height of 790 mm and spans a 1,369 mm wheelbase. That's roughly 39.7 kg lighter than the average scooter motorcycle in our database. The full 2017 Vespa GTS 300 spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2017 GTS 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 cuts out the regular chain cleaning and tensioning that most bikes need.

Considerations

Modest fuel capacity: Range between stops is limited by the 9.08-litre tank - plan fuel stops accordingly on longer routes.

Wear Points & Servicing Notes

Fuelling & injector care

The fuel injection on the GTS 300 needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.

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 300's suspension runs Single arm, 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 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 Load-bearing sheet steel chassis, the GTS 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 300 - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 2017 Vespa GTS 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 300 should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a GTS 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 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.
