Ducati frameless design



Ducati has applied for a patent on a frameless motorcycle that could become the basis for its street bikes, doing away with its usual trellis frame members.

The patent, according to Gizmag.com, is intended to cover the company’s recent MotoGP bikes, but makes references to street bikes and production.

The design uses a large airbox, possibly of carbon fibre, to join the steering head and the subframe and swingarm.

Benefits would include reduced weight and possibly improvements in strength and stiffness.


  1. Prior art has been online for years on Tony Foale’s site and on Eurospares. The steering head bolted to the cylinder head, and the swingarm mounted to the crankcase concentric with the sprocket was done in the ’70s at the latest.
