Yamaha’s V4 MotoGP bike hasn’t gone ‘properly fast’ yet, Fabio Quartararo claims
Fabio Quartararo acknowledges that Yamaha’s current testing of the new V4 MotoGP bike for 2026 has not been focused on pure speed, but that will soon need to change due to the shift in the bike’s philosophy.
Yamaha’s decision to switch from an inline-four to a V4 engine marks a significant change for the 2026 season, with limited V4 testing undertaken last year.
Quartararo’s initial feedback on the V4 has been lukewarm as he considers his MotoGP future beyond 2026.
Yamaha has prioritized building reliability in the V4 engine, opting for lower power configurations during wildcards and tests.
Quartararo believes he will not require a steep learning curve to adapt to the V4 during pre-season testing, focusing on finding the right performance parameters.
