Yamaha has admitted it faces a significant challenge in developing its new V4-powered MotoGP machine after a difficult start to the 2026 season. The project represents a major technical shift for the Japanese manufacturer as it attempts to close the gap to its rivals and prepare for the sport’s upcoming regulatory changes.
Speaking after the opening round of the season in Thailand, Paolo Pavesio acknowledged the scale of the task facing Yamaha as the team works to refine its new concept. He said the company clearly understands the gap to the front of the grid and recognizes that significant development is still required before the bike can consistently compete with the leading manufacturers.
The V4 machine made its full time debut in MotoGP in 2026 after appearing in limited wild card outings the previous year. Yamaha previously relied on its long standing inline four engine design, but switched to the V4 architecture in an effort to improve acceleration, grip, and overall performance against rivals that already use similar layouts.

However, the opening round at Chang International Circuit highlighted the work still ahead. Yamaha riders struggled to match the pace of the leading teams, with Fabio Quartararo qualifying only 16th. In the races, the factory riders finished outside the leading group, and the new bike was reported to be roughly one second per lap slower than the front runners.
Early analysis suggests that some of the expected benefits of the V4 configuration, particularly improved rear grip and stronger engine performance, have yet to fully materialize. Yamaha engineers are still working to establish the base setup of the machine while gathering data from each race weekend.
Despite the slow start, Pavesio stressed that the manufacturer anticipated a long development process when it decided to launch the project. Yamaha began working on the concept last year, building an entirely new bike around the V4 engine rather than simply modifying the previous M1 platform.
He emphasized that progress will take time and warned against expecting quick results. According to Pavesio, the team must focus on gradual improvements as engineers and riders continue to understand the characteristics of the new machine.
The project also carries strategic importance beyond the current season. MotoGP will introduce new 850cc engine regulations and revised aerodynamic rules in 2027, changes that are expected to favor a narrower bike design. Yamaha’s decision to adopt the V4 concept early is partly aimed at preparing for that future technical direction.
For now, Yamaha remains committed to the long term plan. The company believes steady development and continuous data collection will eventually allow the V4 project to reach the level needed to fight at the front of MotoGP once again.
