A Swiss-based company called Quadro introduced what it claims is the “first four-wheel scooter worldwide,” debuting its Quadro4. The selling point of the 346cc scooter is its dual Hydraulic Titling System (HTS) and independent suspensions, each wheel mated to its own shock. The scooter is two-wheel drive, an automatic CVT transferring power to the rear via a dual drive timing belt. The Quadro4 also has a combined braking system on all four wheels based on four 240mm discs. Braking on the front is engaged hydraulically with the right lever, while all four can be activated through either the left lever or pedal. With four contact patches as opposed to two, braking on the Quadro4 should definitely be one of its strong points.

Power is provided by a liquid-cooled, single-cylinder engine with four valves generating a claimed 30 hp @ 7500 rpm. The SOHC engine has an

integrated differential and is fed electronically. Its exhaust runs under the vehicle with the canister residing between its back wheels. It runs 110mm wide, 14-inch tall wheels all the way around, and the machine is claimed to be capable of 45-degree lean angles. In the video from its EICMA debut, a rider is shown dragging his fingers on the ground while maintaining control with one hand without the vehicle falling in.

A four wheel vehicle might be more attractive to car owners because of its familiarity and ease of use, but improved handling in all weather conditions could appeal to seasoned riders as well. The company claims the HTS keeps center of gravity and weight down, and while its seat height is 30.32 inches, its weight is listed at a generous 566 pounds.

Styling is modern and edgy, from its angular front fairing and high intensity lighting system with multiple beams to the small LED turn signals on the sides. There looks to be a couple different small storage areas incorporated in its design, the largest being underneath the back seat. It also has an outlet to plug in media devices or smartphones. It is equipped with a small pillion and fold-out pegs for passengers.
