New for 2017:

  • New Cylinder Head and Intake System
    The compact four-valve cylinder head features revised intake geometry for additional downdraft effect, matched to shorter intake funnel in the airbox, for improved top-end power. Inside the head, more aggressive camshaft profiles and valve springs boost output further, while larger valve seats ensure excellent sealing and reliability.
  • Stronger Connecting Rod and Crankcase
    The entire die-cast crankcase features a new heat treating process to increase strength. Inside, a new nickel-chromoly steel connecting rod offers additional durability to handle the increased power output.
  • Updated Transmission
    New gear dogs, revised gear tooth designs and a host of smaller changes create a smoother overall transmission with improved shifting, as well as a stronger overall powertrain for improved durability.
  • Updated Frame and Suspension
    Revised engine mounts and a reshaped swingarm pivot section of the aluminum frame improve lateral rigidity, while 5mm lower footpegs help lower the rider’s center of gravity for improved machine balance and control, revised suspension settings front and rear to match the chassis updates.
  • Simplified Servicing
    Redesigned air cleaner cover helps prevent contact with the quick-release quarter-turn Dzus® air box fasteners and provides tool-less access to the air filter, positioned at the front of the bike to avoid roost from the rear wheel.

Engine:

  • Innovative Engine Design
    The liquid-cooled, DOHC 4-valve, fuel-injected engine features a forward-positioned straight downdraft intake, with a symmetrical intake and exhaust port layout and a compact, high compression combustion chamber, delivers outstanding engine character, with updates for 2017 designed to further improve top-end power.
  • Piston, Rod and Crankshaft Balance
    A flat-top forged piston features a bridge-box design for additional strength with minimal weight. The piston, rings and DLC-coated piston pin, along with the offset cylinder configuration, all reduce friction loss and contribute to quick response. The engine’s reshaped intake ports, updated cam profiles, ECU, strengthened connecting rod and optimized crank and counterbalancer all work together to give the YZ250F a user-friendly engine character with potent high-rpm power.
  • Advanced ECU and Fuel Injection
    The adjustable fuel injection system uses a 44mm throttle body fed by a high-pressure battery-less electric fuel pump. This ensures optimum fuel atomization and air/fuel calibration for excellent rideability in a wide range of riding conditions. The system controls the volume of fuel injected and the ignition timing based on engine rpm and throttle opening, providing hesitation-free response and controllability. For 2017, new settings provide a smoother feeling as the rider reaches the rev limiter.
  • Wraparound Rear Positioned Exhaust Layout
    An innovative exhaust pipe design improves mass centralization and power development characteristics. This layout moves the rear end of the exhaust pipe farther forward and enables a muffler position close to the center of the mass. An updated midpipe profile improves exhaust gas flow for enhanced mid- and top-end power.
  • Updated Transmission
    The transmission gears, dogs and shift mechanisms are updated for 2017 to smooth gear changes and improve durability under the heavy demands of motocross racing.
  • GYTR Power Tuner Ready Accessory
    GYTR Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons, as well as monitor engine diagnostic codes.

Chassis/Suspension:

  • Bilateral Beam Aluminum Frame
    A Yamaha's renowned bilateral beam aluminum frame features compact overall dimensions that balance minimal weight with the strength and rigidity needed for race-winning performance. This frame features a reshaped swingarm pivot section, updated engine mounting brackets turned for stability, responsiveness and sharp cornering.
  • Mass-Centralization
    The engine, aluminum muffler and fuel tank are positioned closer to the machine's center of gravity. This layout contributes to centralized mass for a lightweight handling feeling on the track. The wide 55mm footpegs have been lowered 5mm to help lower the rider's center of gravity for improved machine balance and control and increased rider comfort.
  • 270mm Front Brake
    A large 270mm front brake disc is the same system fitted to the YZ450F™, and uses an aggressive pad material for exceptional stopping power and braking control. Out back, a new, more heat-resistant rear rotor boots brake durability.
  • Updated Suspension Settings
    Industry-leading, fully adjustable KYB® spring-type fork with speed sensitive damping features revised valving for improved suspension feel and balance. The linkage type rear suspension features a KYB® rear shock also features settings optimized for ideal damping characteristics.
