2025 Yamaha YZ450F

Monster Energy Star Racing Yamaha racer Eli Tomac’s weapon of choice.

Yamaha’s YZ450F sees only minor upgrades for 2025 including revised suspension and an improved clutch.Yamaha

Overview

The YZ450F is another class leader from Yamaha. The premier ranks of AMA Supercross and Pro Motocross call for some incredibly aggressive and capable machines, and Yamaha delivers a package that has been consistently rated at or near the top ranks of both shootouts and pro championships in recent years. For 2025, the Yamaha YZ450F returns with the same engine performance featuring incredibly potent, but usable torque. Updates to the latest from the bLU cRU include new suspension settings and a revised clutch that promises to stand up better to abuse.

This open-class motocrosser features Yamaha’s signature reversed cylinder head that allows for a downdraft air intake system. This is visible by the way the exhaust header curls around the head of the engine. The Kayaba suspension, including the SSS (Speed-Sensitive System) fork, and the Yamaha Power Tuner app are key features of the entire Yamaha YZ family. The Power Tuner app lends to the versatility of the dirt bike, and is also a powerful tool for aspiring racers to log their information, fine-tune engine settings, and trackbike maintenance.

You’re not as fast as Eli Tomac, but you can at least look like him. The 2025 Yamaha YZ450F is available in a black Monster Energy edition.Yamaha
