Toprak Razgatlioglu’s adaptation to the Yamaha M1 has been hampered by rear-tyre issues; he called the Michelin tyres the “real problem” slowing his switch from World Superbikes, highlighting rear grip and acceleration as his main challenges after Brazil. He said the M1’s greater power, aerodynamics and electronics make familiar tracks feel different. Razgatlioglu has improved since Thailand but is still searching for a narrow performance window on the rear tyre and warned that Michelin’s use of a stiffer carcass in Thailand and Brazil, and the planned reversion to the standard carcass for the US GP at COTA, will complicate his learning. Tyre management and suspension/setup choices will be central at Austin, where bumps and a physical first sector may require a softer setup to protect rear grip.

Results in the opening rounds underlined those difficulties: Razgatlioglu failed to score points in Thailand and Brazil, with best race finishes of 17th in both grands prix. He crashed in the Buriram sprint, finished 18th in the Goiânia sprint and was 17th in the Brazilian GP after reaching Q2 and qualifying 12th. He said the sequence of results left him “really down” after Saturday in Brazil. Razgatlioglu has prior experience at COTA — he first raced the circuit in the Red Bull Rookies Cup in 2013 and rode it last year on BMW’s M1000RR — but he said the M1 changes how the track feels.

Support staff and industry figures say the start is technically understandable and that he is improving. Coach Sylvain Guintoli said Razgatlioglu was “getting the hang of” the Yamaha M1 after pre-qualifying at COTA: Razgatlioglu posted a 2:02.373 lap to finish 18th overall and was the third-fastest Yamaha behind Fabio Quartararo and Jack Miller, while Ducati’s Marc Márquez topped the session with a 2:00.927. Guintoli pointed to Friday race simulations as evidence Razgatlioglu is learning to manage throttle inputs, “hook the bike up” and improve traction, while stressing that track temperature and overall tyre grip remain key variables. Ducati test rider Michele Pirro said Razgatlioglu’s difficult start “makes me smile,” noting the switch to the V4 YZR‑M1 requires learning ride‑height devices, increased aerodynamics and running Michelins instead of Pirellis. Pirro warned that being seven to eight tenths off the pace effectively places a rider at the back and that gains often come in small fractions — sometimes half a tenth per corner — but expressed confidence Razgatlioglu can improve as he gains experience with the bike, the Michelin tyres and MotoGP fine‑tuning.
