"APRILIA SR 400 GT: NEW ADVENTURE MODEL ON THE WAY
Aprilia is developing a new adventure scooter with the SR400 GT. Initial details on the technology, design and market position are already known.
Adventure scooters: from niche product to mainstay
The term "adventure scooter" still sounds unusual, but it describes the growing segment of crossover scooters. These models are designed to cope with both unpaved roads and urban traffic. Although off-road capability is mostly limited to easily accessible forest paths, the range is growing continuously. Honda has now sold almost 80,000 units of the X-ADV. There are currently 125cc and 750cc models on the market from SYM, Peugeot and the segment founder Honda. Yamaha is also planning to expand in this segment.
Aprilia SR400 GT: New mid-range model in preparation
Aprilia already offers 125 and 200 cc scooters with the SR GT. The sighting of a prototype in Veneto now points to an expansion of the series. The new model, presumably called the SR 400 GT, is aimed at customers looking for an alternative to the Honda ADV350. The latter also serves as a benchmark for the current test rides.
First design features and equipment visible
Although development is still at an early stage, important details can already be seen. The styling of the heavily camouflaged pre-production model is reminiscent of the last generation of the RSV4 - the front mask in particular is typical Aprilia. Aerodynamically designed components and a modern, slim rear end with integrated rear and brake lights are striking. The classic rear light has been omitted, as is now standard. The seating position looks well thought out: the rider sits upright on a new handlebar, the TFT display should offer common connectivity functions.
Technology: Piaggio basis with independent components
Technically, the SR 400 GT is based on the Piaggio Beverly 400. Accordingly, Aprilia is also likely to use the 399 cc single cylinder with around 36 hp. The swingarm and parts of the chassis also come from the corporate brother. However, Aprilia has gone its own way with the brake system and chassis: a higher-quality, independent brake system is used at the front, while the upside-down fork is a new part with extended suspension travel. There are also new stereo shock absorbers at the rear. The double-loop frame and CVT transmission remain largely unchanged. The currently installed exhaust still comes from the Beverly; whether this will be adopted in series production is open, but unlikely.
Market launch
A presentation date has not yet been set. In view of the development status, however, a presentation at the EICMA this year seems unlikely. The SR 400 GT is still well before it is ready for series production."
