The junior class is preparing for its biggest transformation in decades.
Assen, June 2026
Moto3 will become a one-make championship supplied exclusively by Yamaha beginning in 2028, ending the current competition among several manufacturers in Grand Prix motorcycle racing’s entry-level category. The agreement will run for six seasons, through 2033, and will introduce a new racing prototype based on Yamaha’s CP2 production-engine platform. MotoGP and Yamaha presented the project during the Dutch Grand Prix weekend in Assen. Their stated objective is to reduce costs, improve accessibility and place greater emphasis on rider talent.
The reform represents a fundamental change to the identity of Moto3. Since the category replaced the former 125cc class in 2012, riders have competed on lightweight 250cc single-cylinder prototypes supplied primarily by Honda and KTM, with other brands represented through technical partnerships. Manufacturers have used the championship to develop motorcycles, promote their engineering and identify future stars. Beginning in 2028, every rider will instead compete with the same basic Yamaha machinery.
Yamaha will become the exclusive supplier of both the motorcycle and its power unit. The new machine will not simply be a lightly modified road bike, but a dedicated racing prototype developed around the company’s proven CP2 architecture. That platform is associated with the parallel-twin engine used in models such as the Yamaha R7. The final motorcycle will be extensively redesigned for Grand Prix competition and officially unveiled during 2027.
Early technical information points to a much larger and more powerful machine than the current Moto3 motorcycles. Reports indicate a weight of approximately 120 kilograms and output close to 95 horsepower, although complete specifications remain subject to development. The objective is to produce a superior power-to-weight ratio while creating a full-size motorcycle better suited to the height and physical characteristics of modern young riders. Current Moto3 bikes can be especially restrictive for taller competitors.
The increased engine capacity will also make the transition toward Moto2 more natural. Riders currently move from extremely light single-cylinder Moto3 prototypes to significantly heavier and more powerful Moto2 machinery. That jump can require a major adjustment in braking, acceleration, body position and tire management. A larger twin-cylinder Moto3 bike could prepare young competitors more effectively for the next stage of their careers.
Cost reduction is one of the central motivations behind the reform. Moto3 teams must currently finance engines, chassis, replacement parts, technical development and increasingly long international calendars. Smaller organizations often struggle to remain competitive against better-funded operations with stronger manufacturer support. MotoGP expects the new Yamaha package to cost substantially less than current machinery, with some estimates suggesting a reduction of approximately 50 percent.
Under the planned commercial model, teams will purchase the motorcycles while the engines are expected to be supplied through a leasing arrangement. Yamaha will assume responsibility for engine maintenance and provide technical support at racing circuits. Centralized servicing should reduce the need for each team to maintain extensive development resources. It may also prevent wealthier organizations from gaining decisive advantages through private engine preparation.
A one-make format is intended to make rider performance more visible. When every competitor uses equivalent machinery, differences in racecraft, braking technique, tire preservation and decision-making become more important. Teams will still influence results through setup, engineering quality and rider support, but the competitive gap created by manufacturer performance should narrow. MotoGP believes this structure will ensure that talent remains the defining factor in the category.
The concept follows principles already familiar elsewhere in the Grand Prix paddock. Moto2 uses a common Triumph engine, although teams can choose between a limited number of chassis manufacturers. The Red Bull MotoGP Rookies Cup and several regional development series also rely on identical equipment. Moto3 will go further by adopting a single complete motorcycle supplier for every team.
The decision will inevitably reduce the category’s value as an engineering competition. Manufacturers such as Honda and KTM have historically used Moto3 to demonstrate technical capability and establish relationships with young riders. Their departure removes the rivalry among brands that has formed part of the championship’s appeal. Critics may argue that a Grand Prix class should preserve prototype diversity rather than resemble a standardized development series.
There are also concerns that a single motorcycle may favor particular riding styles. Under the current system, riders sometimes find machinery whose characteristics better suit their strengths. A competitor who struggles with the Yamaha prototype will have no alternative manufacturer available. The championship must therefore ensure that the new machine is adaptable enough to accommodate different sizes, techniques and setup preferences.
Yamaha and MotoGP are presenting the reform as a broader global development platform rather than a change limited to the World Championship. Beginning in 2029, the FIM Moto3 Junior World Championship within the MotoJunior paddock is expected to adopt a slightly lower-specification version of the same motorcycle. Discussions are also underway with regional championships interested in joining the platform. This could create a unified progression system from national competition to Grand Prix racing.
Such standardization may reduce the financial and technical disruption riders experience when moving between championships. Young competitors could learn on motorcycles sharing the same fundamental architecture before advancing to the full World Championship specification. Teams would also gain access to a more predictable equipment structure. MotoGP hopes this will broaden participation beyond the countries and families currently able to finance expensive international careers.
Prototype testing is expected to continue during 2026, followed by the motorcycle’s first complete public presentation in 2027. Yamaha must demonstrate that the new machine can provide the close racing, slipstream battles and unpredictable finishes associated with Moto3. Greater horsepower alone will not guarantee better competition. Weight distribution, aerodynamics, tire behavior and braking performance will determine whether the category retains its distinctive character.
Safety will remain another priority. Moto3 frequently produces large groups of riders separated by only fractions of a second, creating spectacular racing but also significant collision risks. A larger and more powerful motorcycle must be designed carefully to avoid increasing closing speeds or instability. The organizers will need to balance performance with control, visibility and rider development.
The 2027 season will mark the final year of the existing prototype formula before Yamaha begins its exclusive role. For Honda, KTM and their associated brands, the transition will end a significant chapter of Grand Prix competition. For Yamaha, it represents a long-term commitment to the earliest professional stage of the MotoGP pathway. The company will become responsible not only for supplying motorcycles, but for maintaining the credibility and competitiveness of an entire world championship.
Moto3’s future will therefore depend on whether standardization delivers the promised benefits without removing too much technical identity. Lower costs and closer competition could strengthen teams and create opportunities for a wider range of riders. The loss of manufacturer diversity may make the category less attractive to those who value engineering rivalry. Beginning in 2028, Moto3 will test whether equal machinery can produce a fairer and more sustainable path toward the highest level of motorcycle racing.
