The MotoGP world is on the brink of a significant shift, with a potential return to Inline-4 engines. This is a bold statement, considering the current dominance of V4 engines. But here's where it gets controversial... With the sport's upcoming transition to 850cc engines in 2027, the current V4 'edge' from maximizing Michelin rear tires might disappear. This could mean a return to the Inline-4 engines, which have historically held their own against V engines. The shift could be driven by the need for more natural bikes, without ride-height devices, and with less aero, as well as the potential for increased power and efficiency. But with so much knowledge and data built around the V4, and even Yamaha making the switch in search of rear grip, no MotoGP manufacturer is known to be evaluating an Inline 850cc engine project - at least for now. This leaves the door open for a potential comeback of Inline-4 engines, and a return to the days of balanced competition between V and Inline engines. So, is an Inline-4 engine the future of MotoGP? The answer may lie in the upcoming changes to the sport, and the potential for a more natural and efficient bike. And this is the part most people miss... The current V4 'edge' from maximizing Michelin rear tires might disappear, leaving the door open for a potential comeback of Inline-4 engines. But only time will tell if this will be the case, and if the sport will embrace a return to the days of balanced competition between V and Inline engines.
