2024 Yamaha YZ250F Guide • Total Motorcycle

Introducing the new 2024 Yamaha YZ250F…

THE LIGHTER, SHARPER, MORE ADVANCED NEW YZ250F

Lighter, sharper handling, with an all-new frame, more compact body and improved smartphone tuneability, the new generation YZ250F is ready to continue a legacy of dominance in the 250 class.

All-New Aluminum Bilateral Beam FrameA completely redesigned aluminum bilateral beam frame based on the flagship YZ450F provides just the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a better handling machine with lightweight feel and increased front wheel traction, allowing the rider to enter corners with greater confidence and more line choices.

SLIMMER BODY & IMPROVED ERGOSThe new 2024 YZ250F has a slimmer, flatter body design for improved control, including a more narrow fuel tank, lower airbox and more narrow radiator shrouds. The rider triangle is also improved with increased legroom between the seat and footpegs for greater rider comfort.

NEW YAMAHA POWER TUNER APPLike having factory team support in your pocket, Yamaha’s groundbreaking Power Tuner App is revised to be even more user-friendly. New features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction and Launch Control tuning, lap timer, along with helpful engine and suspension tuning guides.

Optimized intake path draws air from under the side covers and seat allowing for a lighter, slimmer and more compact body. This redesign allows radiator shrouds to be slimmer and the airbox cover to be lower and more narrow. The more efficient intake path also boosts mid- to high-rpm engine performance.

Yamaha was born to race. Right from day one Yamaha put competition at the heart of its operations. And 50 years ago, Yamaha launched its first YZ production motocross models – the same year that the company won its first ever Motocross World Championship with Hakan Andersson on a factory YZM250. It was the beginning of a new era for the sport, and over the last half century Yamaha has established itself as one of the most innovative and competitive brands in the 4-stroke and 2-stroke classes.

Yamaha are marking this significant moment in the company’s history with an all new YZ250F that has been created with the immense knowledge gained during half a century of competition in every major GP category.

To commemorate 50 successful years since the first Yamaha YZ models made a lasting impact on the motocross racing world, the 2024 line-up will include exclusive YZ250F, YZ450F, YZ250 and YZ125 50th Anniversary Edition models. Featuring racing white bodywork, purple seats, black wheels and retro-styled purple/pink graphics, these 50th Anniversary Edition bikes offer every Yamaha rider the chance to be a part of this very special occasion.

The 50th Anniversary Edition colouring is inspired by the bold designs used on the YZ250 and YZ125 in the mid-1990s – a period of transition for Yamaha motocross machines which was soon to be followed by the arrival of the first YZ 4-stroke in 1998 and the beginning of a new era of ‘Yamaha Blue’ colours for the company’s Off Road Competition models.

The introduction of the new YZ250F reinforces the range to make the 2024 Yamaha Off Road Competition line-up stronger than ever – with a diverse choice of 4-strokes, 2-strokes, motocross, enduro, youth and kids’ bikes.

New handlebar-mounted switch allows on-the-fly selection between two preloaded engine maps with the push of a button, making it easy to make immediate adjustments to changing track or weather conditions. Maps are loaded and configured within the Power Tuner App.

Advanced 250cc Four-Stroke Engine

The YZ250F’s liquid-cooled, DOHC 4-valve, fuel-injected powerplant features a forward-positioned straight downdraft intake with symmetrical intake ports, high-spec piston and aggressive cam profiles. The advanced four-stroke engine is known for its broad, useable powerband and class-leading low-end and mid-range torque. New for 2024, a more efficient intake path and revised ECU settings results in even more mid- to high-end power.

Advanced Fuel Injection

The adjustable fuel injection system uses a 44mm throttle body, fed by a high-pressure electric fuel pump, to inject fuel through a 12-hole Denso® injector. This ensures optimum fuel atomization and air/fuel calibration for excellent rideability in a wide range of riding conditions.

Durable Clutch

The YZ250F features a large-diameter 15 plate clutch to withstand the high demands of motocross racing.

Innovative New Yamaha Power Tuner App

The free-of-charge Yamaha Power Tuner App brings the power of the GYTR® Power Tuner to your iOS® or Android® device. Using wireless connectivity to talk to the bike’s onboard electronics system, the app allows owners to adjust air/fuel mixture and ignition timing to tune engine character for track conditions, log track set-up information, and monitor a range of data such as maintenance and system diagnosis, engine run time and more. For the 2024 YZ250F, the app has been revised to be more user-friendly. New features include an intuitive “Simple Tuning” slide bar for engine mapping, Traction and Launch Control tuning, lap timer, along with helpful engine and suspension tuning guides.

New Air Intake

A new, optimized intake path draws air from under the side covers and seat more efficiently, resulting in a boost in mid- to high-rpm performance and improved over-rev characteristics. The redesign also allows radiator shrouds to be slimmer and the airbox cover to be lower and more narrow.

Piston, Rod & Crankshaft Balance

A forged piston features a bridge-box design for maximized strength with minimal weight. The piston, rings and DLC-coated piston pin, along with the offset cylinder configuration, all reduce friction loss. Intake ports, cam profiles, high-strength connecting rod, optimized crank and counter-balancer all work together to produce potent high-rpm power with user-friendly delivery and exceptional reliability. New for 2024, a redesigned cam chain improves durability.

Wraparound Rear-Positioned Exhaust Layout

An innovative exhaust pipe design improves mass centralization and power characteristics. This layout moves the rear end of the exhaust pipe farther forward and positions the muffler closer to the bike’s center of mass.

New bilateral aluminium frame With a lower head pipe and new tank rails the YZ250F lightweight bilateral aluminium frame gives improved handling faster and smoother cornering. The lower centre of gravity and reduced weight make the YZ250F 50th Anniversary Edition more agile than ever – and the revised balance of rigidity and YZ250F-speci c engine mounts give plenty of feel and feedback.

Optimized rider ergonomics The revised rider triangle accommodates riders of varying sizes and physiques. The shrouds are 50mm narrower, the atter seat is 5mm higher and the footrests are 5mm lower, providing better ergonomics with enhanced controllability. The new side panels give a tighter and lighter look – and the new smaller front fender improves air ow to the radiators for consistent cooling.

Increased top-end powerThe YZ250F is already regarded as one of the most competitive and responsive 250cc 4-stroke engines in the low to midrpm range. The YZ250F benefits from the new rear duct air-management system together with a reprogrammed ECU that boost top-end engine performance, making this Motocross Grand Prix race winning machine even more competitive for every rider.

Efficient air-managementThe new rear duct air ow system channels fresh air through the spaces between the fuel tank, frame, seat and side panels – resulting in increased top-end engine performance and narrower body width. When air reaches the lightweight airbox it is pre-cleaned by a vortex that throws particles to the side, reducing air cleaner clogging and making routine maintenance easier.

Revised suspension settingsThe YZ250F KYB front forks are widely regarded as being amongst the best in class, and the new generation bike features revised settings as well as a new hand-adjustable compression damping adjuster. The link-type Monocross rear suspension and KYB shock also runs revised settings for high levels of traction and control – and the renewed Power Tuner App contains useful suspension setting data for quick and accurate manual adjustments
