Ducati boss surprised the entire MotoGP when he just presented evidence denouncing Yamaha’s upcoming engine at San Marino as “CHEATING”. Immediately, the FIM president spoke up to confirm !! 👇👇
In a dramatic turn of events that has sent shockwaves through the MotoGP paddock, the owner of Ducati has publicly accused Yamaha of cheating with their highly anticipated new engine, set to debut at the San Marino Grand Prix. The explosive allegations, backed by what Ducati claims is compelling evidence, have sparked intense debate and scrutiny within the sport. Adding fuel to the fire, the chairman of the Fédération Internationale de Motocyclisme (FIM), the governing body of MotoGP, has issued a swift response, confirming that an investigation is underway. This controversy has reignited discussions about technical regulations, fairness, and the fierce competition among manufacturers in the premier class of motorcycle racing.
The accusations stem from Yamaha’s recent announcement of a new V4 engine, a significant shift from their traditional inline-four configuration, which has been a cornerstone of their MotoGP bikes for years. The Japanese manufacturer has been under pressure to close the performance gap with European rivals like Ducati and KTM, especially after a challenging 2024 season where they failed to secure a single race win. The new engine, tested during private sessions and slated for a debut at Misano, was touted as a game-changer for Yamaha’s 2025 campaign. However, Ducati’s leadership, led by outspoken owner Claudio Domenicali, claims that Yamaha’s engine violates technical regulations, specifically regarding homologation protocols and component specifications.

According to sources within the Ducati camp, the evidence presented includes detailed technical data and telemetry suggesting that Yamaha’s new engine incorporates non-homologated components, potentially giving it an unfair performance advantage. Domenicali, known for his candid approach, did not mince words in a press conference, stating, “We’ve seen irregularities that cannot be ignored. MotoGP is a sport built on fairness, and any attempt to bypass the rules undermines the integrity of the championship.” The accusations have drawn parallels to a 2020 incident when Yamaha was docked 50 constructors’ points for using non-homologated valves at the Spanish Grand Prix, a scandal that cast a shadow over their season. Ducati’s current claims suggest a repeat of such tactics, raising questions about Yamaha’s adherence to the strict technical guidelines set by the FIM.
The FIM chairman, Jorge Viegas, responded promptly to the allegations, confirming that the governing body is conducting a thorough investigation. “We take these claims very seriously,” Viegas stated in an official release. “The FIM is committed to ensuring a level playing field for all teams and manufacturers. Our technical team is reviewing the evidence provided by Ducati, and we will make a decision based on the findings.” While Viegas did not elaborate on the specifics of the investigation, his swift acknowledgment has intensified speculation about potential penalties, which could range from points deductions to disqualifications if Yamaha is found guilty.
The timing of the controversy is particularly significant, as the San Marino Grand Prix is a critical juncture in the 2025 season. With Ducati dominating the constructors’ championship and riders like Jorge Martín and Francesco Bagnaia vying for the riders’ title, any disruption to Yamaha’s plans could have far-reaching implications. Yamaha’s riders, including Fabio Quartararo and Álex Rins, have remained tight-lipped, with the team issuing a statement denying any wrongdoing. “Yamaha has always complied with MotoGP regulations,” the statement read. “The new engine was developed within the boundaries of the rules, and we are confident in our compliance.” However, the shadow of the 2020 scandal looms large, and skeptics, including some rival team managers, have expressed doubts about Yamaha’s claims.
The paddock is abuzz with opinions, with some insiders suggesting that Ducati’s accusations may be a strategic move to unsettle Yamaha ahead of a pivotal race. Others argue that the Italian manufacturer’s concerns are valid, given the high stakes of MotoGP’s technical arms race. The controversy has also reignited debates about the clarity and enforcement of technical regulations, with some calling for stricter oversight to prevent such disputes. Fans, meanwhile, are divided, with social media platforms like X buzzing with reactions ranging from support for Ducati’s vigilance to accusations of sour grapes from a dominant manufacturer.
As the San Marino Grand Prix approaches, all eyes will be on the FIM’s investigation and its potential impact on the championship. Will Yamaha’s new engine be cleared for competition, or will Ducati’s evidence lead to a seismic ruling that reshapes the season? The outcome could redefine the competitive landscape and test the resilience of MotoGP’s regulatory framework, leaving fans and teams alike on the edge of their seats.
