Yamaha’s iconic XSR900 has halved her fairings for a purpose-built sibling superbike – and the prototype was just revealed at Goodwood’s Festival of Speed. 

They’re calling her the “XSR900 DB40,” and she’s celebrating forty good years of Yamaha’s iconic Deltabox chassis – first installed on the 1982 YZR500 OW61, now present in models like the 25-year-old R1

“From a side view, the Deltabox is formed of a triangle linking the head pipe to the swing-arm pivot while the cross-section is box-shaped,” supplies Yamaha’s press release, published to Roadracing World. 

“This relationship between the steering head and the pivot point offers outstanding rigidity and feedback where a rider will need it most. The cross-shaped box section allows for a greater surface area while providing lighter weight and a higher level of rigidity.”

The XSR900 DB40 carries an 890cc ‘CP3’ inline-three heart; on the current XSR900, this engine is capable of roughly 117-119hp @ 10,000rpm, with torque yanking out a very nice 93.0 Nm @ 7000 RPM. We haven’t yet been given exact specs for the DB40, but we’re looking forward to hearing the results.
