2011 Kawasaki KFX450R
With its lightweight aluminum frame, long lower front A-arm
suspension and a fully adjustable rear shock, the KFX450R offers track
dominating handling and confidence-inspiring stability to compliment its
powerful engine. At the heart of the KFX is a 449cc liquid cooled, four-stroke engine that was originally borrowed from Kawasaki’s 2008 KX450F dirt bike then slightly reconfigured to perform more ideally in an ATV chassis. The four valve double overhead cam features titanium valves and aluminum valve spring trainers keeping the valve train light for more efficient and reliable operation at high RPMs. Its lightweight forged piston features a compression ratio of 12-1.
Fuel system is 32-bit digital, with 42mm Keihin throttle
Triple piston rings and a 21mm diameter piston pin help
increase durability and reduce necessary maintenance.
System measures coolant temperature, air intake temperature,
air intake pressure, engine speed and throttle position, then automatically
delivers the ideal amount of fuel to optimize power delivery.
Dual-rate front springs deliver progressive suspension travel for
excellent rough-terrain handling
- Extra-long lower front A-arms minimize camber variations through the
suspension stroke, maximize front wheel traction and boost stability.
- Rear shock features both low and high-speed compression adjustability and adjustable rebound
2011 Yamaha YFZ450
Great power output doesn’t mean much without superior
handling. YFZ450R delivers! The stance of the YFZ450R is motocross ready.
The weldless frame is designed from lightweight aluminum, with a
tension-steel bottom frame that lets the engine sit lower for excellent mass
centralization. Suspension components have more travel, carefully chosen for
best performance, and the front shock bodies feature Kashima coating for
even smoother operation.
The fuel-injected 449cc engine has superb power
characteristics. Power delivery is smooth and strong off the line with lots
of low and mid range where you need it.
Fuel injection uses a 12-hole injector that provides exceptional
atomization of the fuel for maximum combustion efficiency and power delivery.
The system also uses a big, 42mm Mikuni® throttle body and includes ISC (Idle
Speed Control) for easy, reliable start-up and warming.
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
