2019 Yamaha Off-Road Models – NEW YZ450FX

A New YZ450FX Arrives

Along with the 2019 Motocross models, Yamaha introduced their off-road bikes today spearheaded by the newly redesigned YZ450FX with the YZ250FX and YZ250X in tow. Following along with the changes the YZ450F received last year, the 450FX adopted many of the same changes as a new frame, engine, suspension, and electronics make up the 2019 edition.

The new engine boasts a new cylinder head, a high compression piston, updated camshaft profiles, steeper cylinder geometry, and a new crankshaft to go along with the updated wide-ratio transmission and clutch that Yamaha claims offers increased durability and a lighter clutch pull for better controllability. For better mass centralization, updated radiators and a new exhaust are also implemented for 2019.

A new electric starter system features a more compact starter motor and a lightweight lithium-ion battery for weight reduction and improved mass centralization. In addition, the WiFi enabled Power Tuner App now connects with the 450FX for mapping changes and data logging while a new dual-mode mapping switch allows for on the fly mapping adjustments.

Similar to the 450F, the FX utilizes a new frame for increased rigidity which improves the bikes handling and also was designed to further centralize the weight of the bike. New bodywork is slimmer and lighter than in years past and with the larger capacity 2.2 gallon fuel tank, slicing through trees and across the desert is easier than ever with improved knee grip and increased rider movement.

Updated KYB SSS spring forks absorb the rocks and roots while new fork lugs provided an improved front end feel with improved handling and stability. The KYB coil-spring shock also features updated valving specific for GNCC style riding and racing.

To separate the FX from its motocross brother, a larger 2.2 gallon fuel tank, wide-ratio transmission, off-road oriented suspension settings, and a new composite skid plate transition the 450F into an off-road race bike. Additionally, a kickstand, an 18 in. rear wheel, an O-Ring chain, and off-road specific ECU settings finalize the off-road conversion.

The YZ450FX is available in Team Yamaha Blue in July 2018 for an MSRP of $9,499.

In addition to the YZ450FX, the YZ250FX and YZ250X are back for 2019 with minimal changes for the new model year. Both received bold new graphics and the YZ250FX received a blue valvetrain cover to compliment the blue rims and plastic. Both are available in June 2018 with an MSRP of $7,999 for the YZ250FX and $7,499 for the YZ250X.
