Jack Miller Explains Why Michelin Tyres Are Challenging Toprak Razgatlioglu in MotoGP

Pramac Yamaha rider Jack Miller has offered insight into why his new team‑mate Toprak Razgatlioglu is still adjusting to MotoGP after moving up from World Superbikes, pinpointing the differences in rear tyre behaviour as a major factor.

Razgatlioglu has been working to fine‑tune his riding style during preseason testing in Sepang and part of that adjustment has involved following Miller on track to learn how to get the most from the sensitive Michelin rear tyre used in MotoGP. Unlike the Pirelli tyres used in WorldSBK, Michelin rubber reacts differently when the rear wheel spins. When spin occurs it can continue into higher gears before grip returns, making corner exit particularly difficult to manage.

The Turkish rider said that controlling wheelspin on the Michelin tyres requires a much smoother throttle approach, similar to riding style used in Moto2. In contrast, Razgatlioglu was used to sliding and using wheelspin to help turn and accelerate on Superbikes, a technique that does not work the same way in MotoGP. He acknowledged it is easier said than done to “ride smooth.”

Miller agreed that controlling spin is crucial with the Michelins and explained that Ducati machines have an advantage because of how they deliver power. The Ducati’s corner exit is smooth and gentle on throttle application, which helps shift load and maintain stability without upsetting the tyre. This makes traction easier to manage compared with some other bikes.

The Australian rider also noted that Yamaha’s previous inline‑four engine struggled more with traction on corner exit, which contributed to the manufacturer’s move to a V4 layout to improve performance and traction.

Razgatlioglu’s challenge with Michelin tyres reflects a broader learning curve as he adapts from Superbikes to MotoGP prototypes. While he already excels under braking, mastering throttle control and minimising unnecessary spin on corner exit will be a key focus as he continues through testing ahead of his race debut in the premier class.
