Overview
- On day one of the official Sepang test, Toprak Razgatlioglu mostly ran without rear wings because his preferred low seating position would breach the FIM seat-unit height limit with wings fitted.
- He switched late in the session to an older, higher seat unit that permitted rear wings, reporting that the bike stopped better under braking.
- Razgatlioglu said he will try to continue with the wings in the next session, noting he must adapt his riding to make the setup work within the rules.
- He explained he needs a smoother MotoGP style and is learning Michelin tyre behavior after years on Pirelli, citing good braking feel but different acceleration characteristics.
- Yamaha has tailored the M1’s ergonomics for his 185 cm frame; he was 20th on the first official test day after setting a 1:58.465 for 10th in the earlier shakedown.
