MotoGP bans 2027-spec bike tests until conclusion of 2025 season

The FIM (Federation Internationale de Motocyclisme) announced a series of changes to the 2025 MotoGP World Championship regulations earlier this week.

The changes, which took effect on 29 April, most notably included the introduction of a test day for riders returning from injury and clarified startline procedures sparked by the recent debacle in Austin.

In addition to the modified regulations, the FIM also announced an agreement regarding testing of prototype bikes that manufacturers are already developing in anticipation of the 2027 season.

A major technical overhaul of MotoGP is coming in 2027, including a shift to 850cc engines, reduced aerodynamics and simplified ride-height devices.

While some manufacturers have already made significant progress on early prototypes for their 2027 challengers, it was agreed in a meeting during the recent Spanish Grand Prix weekend that these bikes cannot be tested on track until the conclusion of the 2025 campaign.

An FIM statement read: “An agreement has been made between the manufacturers that they will not test 2027 specification machines during the 2025 season. This means testing a motorcycle of 2027 specification will only be allowed from 17 November 2025.”

The 2025 season concludes in Valencia on 16 November, but the first 2026 pre-season test is scheduled for the same circuit on 18 November.

Pirelli test unaffected by new rule

In addition to the new technical regulations, MotoGP will also welcome a new tyre supplier in 2027: Pirelli. The Italian manufacturer will replace current French provider Michelin as the series’ sole tyre supplier.

Pirelli will carry out an initial test of its premier-class tyre compounds later this season. For the test, MotoGP manufacturers will provide test riders and a 1000cc bike equipped without ride-height devices and with only a basic aerodynamic package.

The test, which will be fully funded by Pirelli, is set to take place at the Aragon circuit on a yet-to-be-determined date, though it will be after the Aragon Grand Prix scheduled for 8 June.

Autosport confirmed that the Pirelli test remains on track but is still awaiting a final date and is not affected by the new regulation.
