Toprak Razgatlioglu to test Yamaha MotoGP bike on Sunday

Toprak Razgatlioglu will start his new career in MotoGP with a private Yamaha test at Aragon on Sunday and Monday.

The outing, reported by GPOne.com, will mark the triple World Superbike champion’s first laps on a MotoGP machine since 2023.

After Aragon, Razgatlioglu will then share a track with his new MotoGP rivals - minus the injured Marc Marquez - for the first time at the official post-season Valencia test on November 18.

However, Aragon may not be Razgatlioglu’s only 'extra' MotoGP track time this year.

While Honda is on course to lose D concession privileges, Yamaha is expected to retain full benefits, including private test days with contracted riders.

After the official Valencia test, Crash.net understands that Razgatlioglu - who has signed to join Pramac alongside Jack Miller - could swiftly return to the track for another private outing, ahead of the winter ban on December 1.

The ban ends with the Sepang Shakedown (January 29-31), which all Yamaha race riders are also eligible to attend, followed by the official Sepang test from February 3-5.

Yamaha is yet to confirm that its new V4 engine will replace the existing inline-four for 2026, and Razgatlioglu’s machinery for the Aragon outing - starting on the same weekend as the Portuguese MotoGP - is unclear.

The Turkish star last tested a MotoGP bike in early 2023, also with Yamaha, before joining BMW and winning two more WorldSBK titles.

Superbike title rival Nicolo Bulega will beat Razgatlioglu to a MotoGP race debut after being called up to replace injured champion Marquez at Ducati for the Portimao and Valencia rounds.
