wR 450 F - Engine

adjustable injection system:

The WR 450 F's 449 cm³, single-cylinder, 4-stroke, 5-valve, DOHC engine is a favorite of enduro and off-road riders looking for power and control. Equipped with a state-of-the-art fuel injection system, this robust, reliable model is set to become even more popular.

By their very nature, enduro bikes have to endure frequent changes in altitude, air temperature and atmospheric conditions in the space of a few hours. To ensure efficient engine operation in a constantly changing environment, the compact injection system fitted to the WR 450 F model has been programmed to constantly adapt its settings to ambient conditions. To minimize weight, the WR 450 F uses the same lightweight, compact fuel pump as our YZ-F models.

competition parts kit:

A Competition Kit specially designed for the WR 450 F is also available for riders wishing to use their machine on closed enduro circuits. This kit includes several parts specially designed for racing, such as an exhaust elbow, a muffler, a rear exhaust pipe, a set of 13/50 sprockets and much more.

competition exhaust line with resonator:

The exhaust elbow included in the Competition Kit features a resonator designed to optimize the pulsation effect of the exhaust/intake circuit. This resonator already equips the YZ-F models in Yamaha's MXGP range, and contributes to improving the machine's low- and mid-range power.gimes, which is particularly interesting for enduro riding where races are often won where speed is lowest, such as in narrow, winding areas.

easy power adjustment:

The WR 450 F is supplied as standard with standard injection mapping. However, on machines equipped with Yamaha Competition Kit parts, riders can use the Power Tuner to adjust injection volume and ignition timing to suit their particular terrain conditions and riding style.

Compact and easy to use, the Power Tuner does not require the use of a PC to activate mapping changes. All the rider has to do is plug the Power Tuner into the motorcycle's dedicated connector and enter the values corresponding to the desired performance. The Power Tuner allows riders to independently adjust the injection volume at 9 different setting points. Ignition timing can also be set at 9 different points.
By trying out different injection and ignition settings, drivers can create their own mappings, the ones that best suit their driving style and the conditions encountered.

Another advantage of the Power Tuner is its monitoring function, enabling users to observe data from the various sensors, as well as engine running times. A self-diagnosis function for malfunctions also facilitates maintenance.

vibration-resistant radiator:

The WR 450 F features a completely redesigned radiator that ensures stable operation even at low rpm, when airflow is reduced. First used on the latest-generation YZ 250 F, this vibration-resistant radiator has a thicker body and its fastening system now uses a three-point system (previously two) for greater durability.

high-capacity alternator and new capacitor:

To meet the needs of the new fuel injection system, the WR 450 F is equipped with a high-capacity, three-phase magnetic alternator. and, to ensure efficient kick starting even in the event of battery problems, a capacitor has been added to the motorcycle's electrical circuit.

The 2013 WR 450 F features one of the most compact frames on the market.

Featuring two aluminum spars running from the steering column to the engine cradle, this new bilateral-beam frame has been designed from the YZ 250 F model to offer a significant number of advantages over the previous version.

This bilateral design has enabled engineers to reposition elements such as the fuel tank and radiators to better center the machine's weight and allow easier, quicker steering changes in tight corners.
