Toprak Razgatlioglu is running without rear wings on his Yamaha in Sepang MotoGP testing
Toprak Razgatlioglu, the MotoGP rookie riding for Pramac Yamaha, made headlines by testing without rear wings on his Yamaha M1 at the official Sepang test. He is a three-time World Superbike champion debuting in MotoGP this season with a multi-year deal. Razgatlioglu first tested Yamaha’s new V4 late last year in a private outing and then publicly in November in Valencia. Despite Yamaha debuting an aggressive new aerodynamic package on its M1 at Sepang, Razgatlioglu’s bike notably lacked rear wings due to height restrictions.
The rear winglets were first introduced by Ducati in the 2022 British Grand Prix to provide more downforce, now a standard feature in MotoGP. Razgatlioglu, being the tallest rider at 185cm, had to forgo rear wings due to height regulations. The FIM MotoGP rule book sets a maximum height for the seat unit behind the rider’s position, limiting the use of rear wings for taller riders. Despite initial tests with rear wings, Razgatlioglu’s height restricts him from using them in official tests, unlike the slightly shorter riders on the grid. Yamaha will have to work on a solution to optimize his setup as the season progresses.
