The 2023 MotoGP™ Sepang Test was a fascinating watch, with the factories putting their winter hard work into motion for three days of rigorous testing in Malaysia. There were no huge updates for the reigning World Champions at the Sepang Test. At the Valencia Test they brought Aprilia’s ground-effect aero to the table. In Sepang, there was an updated version of Ducati’s interpretation. A new chassis, swingarm, tail unit and updated exhausts were a few of the things spotted at the Sepang Test, while a new 2023 engine specification will arrive for the Portimao Test. The KTM and GASGAS riders were also busy testing aero upgrades in Sepang. A new engine was also tested, as well as more than one chassis. There were two new aero updates in Sepang, one of those boasting big wings and sidepods – and bigger wings mean greater downforce.
