Motorcycling Australia (MA) has backflipped on its decision to outlaw the Mectronik YMER6WSS Yamaha R6 ECU in the Australian Superbike Championship (ASBK) ‘in the best interests of the sport’, with a complete review of the approved ECU list to take place at the conclusion of the 2024 season.

The national governing body had initially removed the Mectronik ECU from homologation last month in a controversial mid-season review, causing an uproar from those already invested in the Mectronik option that had been legal from 2017.

“After further investigation, it has been determined to defer the original determination removing the YMER6WSS ECU from the Manufacturers Nominated Kit ECU and MA Approved ECU List for SBK and SS classes,” read a statement circulated by MA this afternoon.

“The initial determination, although valid and within power, has been deferred in the best interests of the sport. A complete review of the approved list has been scheduled for the end of the 2024 season and until this review is completed, it has been determined to reinstate the YMER6WSS ECU to the list.”

Two-time Australian Supersport champion Tom Toparis currently uses the Mectronik system with Stop and Seal Racing, the Queensland-based operation fielding a total of five riders aboard Yamaha YZF-R6 machinery in the middleweight division.
