Yamaha handed MotoGP points deduction for technical infringement

An FIM ruling said Yamaha failed to respect the protocol and docked the constructor double the points it earned from Fabio Quartararo's victory in Jerez.

The Monster Energy Yamaha factory team has also had 20 points deducted from its championship tally, while satellite outfit Petronas Yamaha SRT was docked 37 points.

Yamaha has been docked 50 constructors' championship points by MotoGP stewards after making technical changes to its engine without obtaining unanimous approval from other manufacturers, the sport's governing FIM said in a statement on Thursday.

Autosport had reported that Yamaha was under investigation by stewards for allegedly breaching homologation rules with engines used in the season-opening Spanish Grand Prix.

An FIM ruling said Yamaha failed to respect the protocol due to an "internal oversight" and docked the constructor double the points it earned from Fabio Quartararo's victory in Jerez.
