Carbon fibre swingarms banned in Moto3

The Grand Prix Commission has announced a pre-emptive ban on the use of carbon fibre swingarms in the Moto3 World Championship.

Such swingarms are not used by either Honda or KTM, the only manufacturers in the junior class, but are already being run by most of the MotoGP manufacturers, while Kalex is on course to join Speed Up in having a carbon-fibre swingarm in Moto2.

A further 2020 rule amendment, for both Moto3 and Moto2, will see testing limited to two official tests (each of three days) between 1 February and the first event of next season.

One private test of two days will be available during the season at a circuit agreed by the teams, plus six days per rider of private testing at a circuit in Europe or at a circuit in the country of the team.

Any testing after the last event of the previous season and before 30 November will count towards the maximum of six days of private testing per rider. Previously, testing in this period was unrestricted.

The only announcement involving the MotoGP class was a change to the CAN layout to allow for the introduction of the X2 Racelink Pro device:

'The X2 Racelink Pro will be mandatory on all MotoGP Class machines, and it will provide, amongst other things, an improved GPS positioning for Race Direction, and real-time communication for Race Direction messaging and virtual pit board displays.

'The X2 Racelink Pro will be powered by the motorcycle electric system and will need a specific and additional GPS antenna to be placed on all machines.'
