Yamaha is gearing up to introduce an evolution of its distinctive tri-plane front wing concept for the upcoming 850cc MotoGP era set to begin in 2027. The wing, which has been a hallmark of the M1, is being adapted to meet stricter bodywork regulations and lower horsepower.
A photo circulating online shows test rider Augusto Fernandez's 850cc Yamaha prototype fitted with a revised tri-plane arrangement. Three distinct wings are visible on each side of the nose fairing, but they are now smaller and without the loop that joins the outer edges on the current 1000cc design.
2027 Aero Regulations: Tighter Limits
From 2027, the maximum permitted width of the upper front fairing reduces from 600mm to 550mm, while maximum rear-end height drops from 1250mm to 1150mm. The foremost point of the front fairing also moves back by 50mm, and the rearward taper of front-fairing aero appendages narrows. These changes force manufacturers to redesign their aerodynamic solutions.
Yamaha has already shown a clear preference for the tri-plane solution throughout the 2026 development. They began the season with a box-wing design, then returned to the tri-plane concept from the previous inline-powered machine. The factory then used its D concession ranking to introduce a further front wing evolution that remains in use.
Impact on Line-up and Competition
For the 2027 season, current championship leader Jorge Martin will join Ai Ogura at the factory Yamaha team. Meanwhile, Toprak Razgatlioglu remains at Pramac and will be joined by rookie Izan Guevara. Ducati's latest 850 prototype currently features a single-plane front wing, and factories are expected to delay revealing their final 2027 aero designs until winter testing before official homologation at the Thai season opener.
The 2027 regulations also change the ability to update rear aero. From next season, all rear aerodynamics must be homologated as part of the Aero Body. This means manufacturers will only be allowed one rear-aero update during the season, depending on their concession status.
With Yamaha's move, competition in the 850cc era is predicted to intensify, especially in aerodynamic innovation which is key to on-track performance.
