# Fabio Quartararo and Yamaha development dispute > Live situation record from CLSTR: https://clstr.news/situations/fabio-quartararo-and-yamaha-development-dispute > Updated: 2026-09-11T08:23:11.000Z. Sources: 16. Developments: 3. Following the Grand Prix weekend at MotorLand Aragón, tensions rose between MotoGP rider Fabio Quartararo and Yamaha. Quartararo, who is scheduled to leave the manufacturer after the 2026 season, refused to participate in long-term development projects for 2027, stating he did not wish to act as a ‘test rider’ for components that provided insufficient improvements. This friction was exacerbated by Yamaha’s decision to bar him from a planned Pirelli tire test at the Red Bull Ring. Yamaha leadership responded by criticizing Quartararo’s professionalism, with senior official Paolo Pavesio questioning his objectivity and Massimo Meregalli suggesting he emulate the attitude of Jack Miller. During the Misano Grand Prix weekend, the parties moved toward reconciliation. Yamaha Team Director Massimo Meregalli confirmed that a meeting was held to clarify the situation, stating, “I think I have understood the weight of the words spoken by Fabio after the Aragon GP. When he arrived yesterday, we clarified everything.” Quartararo acknowledged that his comments were driven by frustration, admitting, “perhaps we said things that were not right,” and expressed a need to manage his outbursts more delicately. Despite the upcoming conclusion of their collaboration at the end of the 2026 season, Yamaha intends to maintain a professional relationship and will continue providing technical developments to the rider for the remainder of his term. ## Timeline ### 2026-09-11: Fabio Quartararo and Yamaha reconcile after Aragon GP tensions MotoGP rider Fabio Quartararo and Yamaha have resolved tensions following public outbursts of frustration after the Aragon Grand Prix, agreeing to maintain a professional relationship through 2026. 5 sources. https://clstr.news/cluster/fabio-quartararo-and-yamaha-reconcile-after-aragon-gp-tensions ### 2026-09-09: Fabio Quartararo and Yamaha resolve tensions after Aragon GP dispute Fabio Quartararo and Yamaha have met to resolve tensions following public disputes regarding bike development and testing restrictions after the Aragon Grand Prix. 2 sources. https://clstr.news/cluster/fabio-quartararo-and-yamaha-resolve-tensions-after-aragon-gp-dispute ### 2026-09-01: Fabio Quartararo and Yamaha face tension over development roles Fabio Quartararo and Yamaha face growing tension after the rider refused to assist with 2027 motorcycle development following a difficult weekend at the Aragón Grand Prix. 9 sources. https://clstr.news/cluster/fabio-quartararo-and-yamaha-face-tension-over-development-roles --- Cite as: Fabio Quartararo and Yamaha development dispute.
