Hugh Janus Posted July 20, 2023 Share Posted July 20, 2023 Yamaha’s XSR900 DB40 Prototype was unveiled at the Goodwood Festival of Speed. (Yamaha/)The annual Goodwood Festival of Speed has evolved into a major event in the 30 years since it first took place as a hill climb for classic race cars and motorcycles along the driveway of Goodwood House in 1993. Today it’s regularly used for major new model unveilings, so the appearance of a prototype Yamaha called the XSR900 DB40 was a clear indication that it’s a machine that’s destined for production in some form in the future.Ridden up the hill by former 500cc Grand Prix front-runner and three-time British Superbike Championship winner Niall Mackenzie, the XSR900 DB40 Prototype was ostensibly a celebration of the 40th anniversary of Yamaha’s Deltabox aluminum chassis concept, which first appeared on the 1982 YZR500 OW61 GP bike and reached the street with the 1985 TZR250. Developments of the Deltabox have been a key part of every major Yamaha sportbike since then.Former 500 Grand Prix racer and multitime British Superbike champ Niall Mackenzie on the DB40 at Goodwood. (Yamaha/)But it’s the term “Prototype” in the bike’s name that’s more significant than the “DB40″ element. It’s a clear hint that this is a test bed for a future production model, and that aligns very neatly with previous clues that Yamaha is developing not one but two different faired sportbikes around the 889cc CP3 engine and the alloy Deltabox chassis used in the XSR900 and the current MT-09 roadster. More than a year ago, we revealed that Yamaha had trademarked the name “XSR GP” and speculated that it was likely to be used on a sport version of the XSR900. Beyond that, the company has also trademarked both names and stylized logos for an upcoming YZF-R9, likely to use the same chassis and engine but wrapped in modern-looking bodywork to align with the R3, R7, and R1.A closer look at the XSR900 DB40’s bodywork.

The main frame and the CP3 engine are direct carryovers, but the DB40 Prototype adds a higher-spec KYB fork similar to those of the MT-09 SP, plus an Öhlins shock, again aping the MT-09 SP.

The likely production version could even go a step further by adding lower fairings—the straight-edged lower cut off of the DB40′s panels look tailor-made to mate to a bellypan to create a fully faired machine.
