Class exclusive yfz450 features: Liquid-cooled,439cc,5 valve, dohc, four-stroke with titanium valves features 95mm bore and 62mm stroke delivering, broad torque curve (for instant hook-up) with high over-rev capacity and crisp, linear throttle response. California green sticker compliant. Reliable, push button electric start in any gear adds extra convenience. Dry sump engine carries oil in an aluminum tank directly in front of the engine for excellent cooling and optimal protection from rocks or mud. High performance 39mm keihin fcr flat slide carburetor with throttle position sensor (tps) delivers ultra-precise fuelair mixing and instant throttle response. Lightweight titanium valves (first ever on an atv) and load-reduced springs are super light, minimizing reciprocating mass for fast revving, hard hitting power delivery across the RPM range. Ignition coil is integrated into the spark plug cap, the first time ever used on an ATV, and is extremely light and compact. Additional weight-saving engine features include: Magnesium cylinder head cover right side crankcase cover; small design cam chain tensioner and oil pump; aluminum oil hose; and light cdi ignition unit.

Engine: Digital CD ignition system delivers ultra precise spark and 3D timing for faster, stronger engine response during hard acceleration. Lightweight crankshaft keeps inertial mass to a minimum for faster-revving low RPM response. High performance stainless steel exhaust header (and heatshield) is mated to a usfs approved spark arrestor which looks trick and resists corrosion. The large capacity radiator is optimally mounted in the frame to keep the center of gravity low but away from mud or rock damage and provides outstanding cooling efficiency.
