Yamaha YZ 450 F 2024 — Specifications

Can a motocross bike still surprise us? When it comes to the Yamaha YZ 450 F, the answer is a resounding and massive yes. This isn't a simple aesthetic update, but a philosophical overhaul where every gram, every horsepower, every frame angle has been redesigned for one reason: to make the rider forget the machine. The 2024 Yamaha YZ 450 F isn't an evolution, it's a piloted revolution, a concentrated dose of raw technology that puts the human at the center of the equation. At nearly €10,500, it clearly targets competition riders, experts seeking the ultimate weapon to dominate the stopwatch, not beginners discovering ruts.

The heart of the beast, this 449.7 cm³ single-cylinder engine, has undergone a complete overhaul. The objective? More power, less weight, a more instinctive response. The result: a 5% power gain and a redline pushed up by 500 rpm. But the most impressive thing is how this power is delivered. It’s linear, manageable, almost pedagogical. The torque? It’s there, immediate, but without that sudden brutality that throws you out of the corner. The redesign of the intake, with its 39 mm valves, and the redesigned exhaust contribute significantly. This is far from unpredictable machines; this YZ 450 F speaks clearly, it listens. For those who want to push personalization even further, adding a racing exhaust like the Akrapovic Yamaha YZ 450 F S-Y4MET14-CIBNTA is a given, releasing a few extra horsepower and further lightening the rear.

All this mechanical fury would be useless without a frame to match. And here, Yamaha hits hard. The bilateral aluminum frame has been reworked to offer a perfect balance between rigidity and flexibility. The result on the track is disconcerting agility. The bike changes direction with a lightness that defies its displayed weight of 109 kg fully fueled. It's precisely this weight, or rather its absence, that impresses. As a comparison, this is a massive argument against some competitors who struggle to drop below the symbolic 110 kg mark. The question "What is the weight of a Yamaha YZ 450 F?" finds its most convincing answer here: it is one of the lightest in the segment, and you can feel it in every lean, every jump.

Ergonomics have also been scrutinized. The slimmer, flatter riding position allows for unprecedented speed of body transfers. The seat, 965 mm high, may be impressive on paper, but its flattened profile and rounded sides greatly facilitate mobility. It's a bike that disappears beneath you, becoming an extension of your own balance. The KYB suspensions, already excellent, are now accompanied by a Power Tuner application that completely demystifies their adjustment. Even the brakes, with their single-piston rear caliper, have been retouched to offer more feel. The traction control system and the adjustable launch control are the icing on the cake, offering a safety net of electronics without compromising sensations.

So, who should rush to get this 2024 Yamaha YZ 450 F? The competition rider, period. It's a precision tool, demanding, that rewards aggression and technique. Its price, around €10,500, places it at the top of the range, but it justifies every penny by its level of refinement. It renders previous generations obsolete, whether it's the 2019 or even the 2020 YZ 450 F. For enthusiasts looking for a reference on the used market, the price of a Yamaha YZ 450 F 2015 or 2016 in France becomes even more interesting as this newcomer pushes the limits. It has no major flaws, if not to demand a rider up to its level. It is the modern definition of a motocross bike: intelligent, lightweight, powerful and totally subservient to the will of the one who straddles it.
