In any walk of life there has to be a leader. In the sports ATV world, that
leader is the YFZ450R. This hard-hitting, race spec ATV is designed from the
ground up to get you to the top step of the podium.
Core to this success
is the YFZ’s fire-breathing, five titanium valved, short-stroke engine,
wicked power-to-weight ratio and meticulously designed chassis, suspension,
wheel and brake package.
The fuel injection system with its big 42mm Mikuni throttle body and
12-hole injector provides exceptional atomisation of fuel for maximum power
and unbelievably crisp power delivery.
And the weld-free aluminium frame is carefully tuned for minimum weight
and maximum durability to take you to the next level of handling
performance.
Then there’s the roomy cockpit, soft contact plastics and plush seat that
offer a lifeline during those long motos.
Massive midrange, incredible performance and a wide track add up to
championship winning potential. Start clearing your throat and try to
remember all those sponsors.
Features:
Nearly 75mm wider overall than the YFZ450, the stance of this 450R is motocross-ready.
|
| The lightweight aluminium frame with high tension steel bottom frame lets the engine sit low for excellent mass centralisation. |
| Long travel suspension components are carefully chosen for best performance, with front shock bodies featuring Kashima coating for smooth operation. |
| Four-position adjustable handlebars allow every rider to choose their best position, while the all-day comfortable throttle and revised engine balancer improves ergonomics even further. |
| The YFZ450R’s designers made this ATV roomy, with plenty of space to hang off in the corners, and the seat padded just right to be more comfortable regardless of riding position. |
| Fuel injection offers precise fuel delivery. With big 42mm MikuniŽ throttle body and 12 hole injector, this system provides exceptional atomisation of the fuel for maximum power. |
| Crankshaft and counterbalancer have optimised ratio for superior vibration control. The crankcase also houses the oil tank, which helps to centralise mass for unmatched handling and makes maintenance easier. |
| The fuel-injected 449cc engine uses the cylinder head and cylinder from the YZ450F for superb power characteristics. Power deliver is smooth and strong off the line with lots of low and mid range where you need it. As rpm climbs you’ll find the same top end punch that has made the YFZ450 such a fierce competitor and class leader. |
| Camshafts designed to maximise torque available in the low and mid ranges. |
| Body panels that the rider contacts during operation are of a special, soft plastic material for high comfort levels. |
| Seat is narrow in the front, yet wide and padded in the rear to provide a more comfortable ride, even when hanging off on the side of the seat in a turn. |
| Wheels are set motocross-spec wide near the maximum allowable width, for great cornering ability. |
| The Dunlop front tyres have the right compound, tyre profile, tread pattern, and sidewall-to-tread-centre-stiffness ratio to provide outstanding comfort, bump absorption, and precise cornering performance. |
| At 20 inches rear and 21 inches front, the tyres also provide great ground clearance, which makes the YFZ450R fun to ride in the bush, too. |
| ProTaper handlebars are mounted on 4-way clamps for exceptional adjustability. There are two sets of holes in the handlebar crown, and eccentric clamps so the rider can choose the standard setting, 10mm or 20mm forward, or 10mm back. |
| Frame is aluminium for lightweight, except for the frame member under the engine. Here tensioned steel is used for its combination of strength and thinness. This allows the designers to sit the engine lower overall for excellent mass centralisation for unmatched handling. |
| The front frame is noticeably narrow at the A-arm mounting points. This dramatically reduces changes in camber as the long A-arms travel through their full range of motion. The front 44mm KYB shocks have Kashima coating for smooth operation with superb bump absorption and excellent anti-bottoming characteristics. The 250mm of wheel travel means this racer is up to even the most challenging tracks. |
| For excellent stopping ability, YFZ450R features dual front hydraulic disc brakes and a trick looking, lightweight wave-type rear rotor. |
