From a press release issued By Aprilia and its website:

An embodiment of Aprilia’s motorcycle heritatge.

The new mid-size GT scooter embodies Aprilia’s motorcycling heritage, ready to conquer any route – agile and responsive in the city, yet comfortable and unstoppable on even the most adventurous rides. It is pure Aprilia, with an all-new chassis designed to deliver precision and control on the road, yet fully capable of venturing beyond the tarmac. This versatility is ensured by its long-travel suspension – with a motorcycle-type fork attached to the frame by a double yoke – and its tyres with a deeper tread pattern. Riding enjoyment comes from its class-leading weight-to-power ratio, with 36 hp from a modern liquid-cooled single-cylinder engine and a ready-to-ride weight of 186 kg. Standard equipment includes a 5-inch TFT display, keyless system, traction control and ABS – both adjustable and deactivatable. The underseat compartment can hold a full-face helmet and other items, while the windscreen is adjustable to five different heights.

The new 400 hpe Euro 5+ single-cylinder engine with 36 HP and a curb weight of only 186 kg delivers the best power-to-weight ratio in its category. That means thrilling acceleration, superior agility and pure fun — both in the city and beyond. Its compact chassis, 41 mm upside-down fork, twin rear shock absorbers and an active riding position turn every ride into a rush of adrenaline.

Aprilia SR GT 400 is designed to stand out: sharp lines, details inspired by sportbikes and off-road attitude, full-LED lighting and an adjustable windscreen.

The 5" TFT color display, Keyless system, adjustable ATC traction control and dual-channel ABS complete a high-tech package where every element is crafted to excite at first glance and deliver functionality in any condition.

Sporting heart
The 400 cc engine delivers 26.4 kW at 7,500 rpm, with a weight-to-power ratio of just 7 kg/kW, placing it at the top of its category for thrilling performance and exceptional responsiveness.

Power is always under control thanks to the Ø 300 mm floating front disc with radial caliper and two-level traction control, ensuring a precise, safe, and engaging riding feel.

Responsiveness without compromise
The active riding position, wide handlebar, and compact wheelbase ensure precision, stability, and agility in every situation. Weighing just 186 kg, it's perfect for navigating city traffic with ease and dominating any terrain with full control.

Adventure-ready range
The underseat compartment accommodates a full-face helmet and other essentials, while the 12-liter fuel tank guarantees extended range—perfect for venturing beyond city limits.

Smart technology
The SR GT 400 comes equipped with full LED lighting, a keyless system, and a 5” TFT display, giving you all the essential information at a glance. With the optional Aprilia MIA system, it connects to your smartphone to manage calls, music, and navigation in an intuitive, smart way.

Versatility in every detail
Ready to go off the beaten track.

A 190 mm ground clearance, 16” and 14” wheels, and an upside-down fork with double yoke ensure stability and control even on uneven surfaces, turning every ride into a safe and dynamic experience. Dual rear shock absorbers with separate reservoirs and a manually adjustable windshield enhance comfort and versatility, making every trip—from daily commutes to weekend getaways—an adventure to enjoy with character.
