Watch: Jack Miller and Toprak Razgatlioglu hilarious MotoGP go-kart antics on full display

MotoGP stars might be known for their abilities to ride at speeds in excess of 200mph, but this unseen footage from a go-kart race at the recent Japanese Grand Prix, is just as compelling to watch. 

Pramac Yamaha riders, Jack Miller and Toprak Razgatlioglu, are considered two of the biggest personalities on the grid, and that was on full display during the go-kart event at Motegi.

Yes, this was the same race that copped Marc Marquez a slap on the wrist from championship officials, after he was replaced by a ‘stunt double’. 

But while Marquez found himself in hot water with MotoGP officials, Miller and Razgatlioglu had the time of their lives, as shown in this unseen footage shared by the championship on its YouTube channel.

Sadly for MotoGP fans, Miller is set to move over to WorldSBK next season after being replaced by Moto2 rider Izan Guevara. 

Miller’s move to WorldSBK will bring an end to his 12-year career in the premier class, where he’s collected four wins in total. 

Miller and Razgatlioglu have formed one of the most charismatic MotoGP pairings during their first season together in 2026.

That’s despite Yamaha’s continued struggles to be competitive against the likes of Ducati and Aprilia in particular, but also KTM and Honda. 

In the video, which you can watch below, the go-kart race starts with Miller and Razgatlioglu bantering about jumping the start, which quickly escalates into other wild ideas the pair have.

Miller, lamenting a lack of power from his kart, then decides he wants to cut the track to gain time, but instead, the Australian cuts through an in-field section of the track, bypassing parked cars and waving to fans. Meanwhile, Razgatlioglu can be seen going backwards on the track while being pushed forwards by other MotoGP riders.
