Yamaha has unveiled its latest V4-powered M1 MotoGP prototype just ahead of its first race appearance at the San Marino Grand Prix this weekend. The Japanese manufacturer showcased the bike, featuring a striking blue design, at its hospitality unit within the Misano paddock on Thursday.
Despite the V4 challenger undergoing several months of private testing, this marks the first occasion the public has seen Yamaha’s innovative machine. The bike is set for its official race debut on Sunday, with test rider Augusto Fernandez lined up to pilot it.
Development and Testing Behind Yamaha’s Bold Engine Shift
Fabio Quartararo, Yamaha’s lead rider, sampled the new bike during a private test session in Barcelona on Monday and is expected to ride it again during the upcoming Dorna test at Misano. Yamaha’s transition to a V4 engine represents a major departure from its traditional inline four-cylinder layout, prompting a full redesign of the M1’s structure and dimensions.
Until now, Yamaha has been the only MotoGP constructor using an inline four-cylinder engine but has concluded that this design has reached its maximum potential. This strategic switch aligns with Yamaha’s long-term goals despite the upcoming regulation changes scheduled for 2027, which will introduce 850cc engines.
Understanding the Impact and Future Plans for Yamaha’s V4 Machine
The new 1000cc V4 engine is currently planned for a full debut in 2026, while current MotoGP regulations might restrict riders Fabio Quartararo and Alex Rins from using the V4 bike in races before the season’s end. Unlike other manufacturers, Yamaha benefits from greater flexibility to implement engine updates during the season as a concession manufacturer.
Nevertheless, the new M1 is considered a completely fresh machine rather than an update, reflecting Yamaha’s commitment to innovation as it prepares for future competition challenges.
