Descriere

Deoarece cursele se castiga sau se pierd pe viraje, YZ450F a fost proiectat sa le abordeze mai bine ca niciodata. Aceasta motocicleta iti va permite sa te inscri rapid in viraj, sa deschizi gazul mai devreme si sa il tii asa mai mult timp.Principale caracteristici ale noului YZ450F sunt motorul revolutionar in patru timpi, alimentat prin injectie, racit cu lichid, cu patru supape, actionate de doi arbori cu came, inclinat posterior si un cadru avansat, din alumniu, ale carui componente sunt distribuite pentru o cat mai buna centralizare a maselor si o manevrabilitate de exceptie. Suspensiile sunt extrem de capabile, menite sa te mentina cat mai mult in contact cu suprafata de rulare. E limpede, YZ450F este cel mai mare avantaj pe care il poate avea un pilot de motocros, depinde doar de tine ce faci mai departe.

Caracteristici

Revolutionary engine

The 450cc, liquid-cooled, 4-stroke, 4-valve rearward-slanting engine brings incredible intake efficiency and better mass centralisation by swapping the fuel intake and exhaust. This gives a straight fuel intake for more efficient cylinder filling, and helps centre the bike’s mass for brilliant cornering.

Bilateral Beam aluminium frame

Different types of aluminium are used on different parts of the precision-formed frame, for the best balance of strength allied to great rigidity. Sideways shock is smoothly converted into up-down shock that is absorbed by the suspension. For you, this means a light, strong frame that handles and corners wonderfully.

Fuel injection

The YZ450F’s fuel injection automatically adjusts to give the best possible combustion under changing conditions. A throttle position sensor (TPS) and sensors for the intake pressure, intake air temperature, air pressure, crankshaft rpm and coolant temperature constantly monitor how the engine is running and make adjustments accordingly.

The YZ Power Tuner (optional)

The YZ Power Tuner lets you set the power development characteristics of your bike without using a laptop. It could be a richer fuel/air ratio at low rpms for strong traction in mud; or a lean mixture in the high-speed range, for lighter revs. It's up to to you. It’s easy to use with a simple interface and easy-to-set 3D programme maps.

Rigid, black rimmed, rear wheel spokes

At the right angle and the right length, the YZ450F’s rear wheel spokes offer a suitable level of ‘forgiveness’ in the back wheel, for improved riding feel and enhanced traction in any conditions. The large-diameter 25 mm rear axle is bigger than most competitor bikes, and gives great rigidity balance for extra confidence.

Aggressive styling

The elegance of the YZ450F’s mechanics has been emphasised by keeping the body as bare as possible with minimal plastic body parts. Those that remain are sleekly styled – a fishtail rear fender gives the image of a departing motorcycle, and the front fender has a darting-forward shape. In the garage or on the track, this is a great-looking bike.
