Back in the 1980s, Yamaha revolutionized motorcycle engineering with the introduction of the Deltabox chassis in their Grand Prix racing machines. This cutting-edge technology eventually made its way into Yamaha's road bikes, and four decades later, the Deltabox design continues to be a core feature in many Yamaha motorcycles.

The XSR900 DB40 Prototype features the renowned 890cc 'CP3' triple-cylinder engine, known for its charismatic performance. It is housed within the latest version of the Deltabox-style frame, showcasing the timeless appeal and functionality of this iconic chassis design.

From a side view, the Deltabox chassis forms a triangular structure that connects the head pipe to the swing-arm pivot, while its cross-section takes a box-shaped form. This configuration ensures exceptional rigidity and precise feedback in crucial areas for the rider. The cross-shaped box section maximizes surface area, resulting in a lighter weight chassis with superior rigidity.

Yamaha first introduced the Deltabox chassis in their 1982 YZR500 OW61 Grand Prix machine, and just three years later, it made its debut in a production racer, the TZR250. Since then, the Deltabox has become synonymous with Yamaha's Supersport models, including the groundbreaking R1, which celebrates its 25th anniversary this year.
