Overview
- Yamaha confirmed Toprak Razgatlioglu and Augusto Fernandez will run in Monday’s Brno test, with Fabio Quartararo, Alex Rins and Jack Miller omitted from the two-bike allocation.
- Honda will use departing HRC riders Joan Mir and Luca Marini to evaluate its 850cc prototype and the new Pirelli rubber that replaces Michelin for 2027.
- KTM has agreed to let Pedro Acosta try its 2027 bike despite his move to Ducati next season, and several manufacturers are pairing one race rider with a test rider because of limited machines.
- Organisers and teams say the test is private with no media access and no official timing, and most factories expect to bring roughly two prototypes and a limited tyre supply each.
- The narrow roster concentrates early technical feedback on contracted or experienced testers, which raises seat pressure for excluded riders and may limit the breadth of input Pirelli and manufacturers can use before the December Valencia test.
