Engine
OIL CIRCUIT
The engine is equipped with two oil pumps and a common oil circuit. A pressure pump supplies reliable lubrication to the crankshaft, piston, balancer shaft and valve controls. It also ensures cooling of the ignition and lubrication of the clutch. A suction pump draws oil from the crankcase and uses it to lubricate the transmission.
ENGINE
Developed for tough enduro conditions, the 510.4cc SOHC engine is characterised by an extremely compact design, very easy maintenance and outstanding robustness, with weight kept to a minimum. Together with the Keihin fuel injection system, this results in unrivalled performance and rideability - specially designed for enduro use.
STARTER
The 500 EXC is equipped as standard with both kickstarter and electric starter. Positioned behind the cylinder, the electric starter is well protected.
CYLINDER HEAD
The cylinder head is equipped with an overhead camshaft. This actuates two titanium intake valves plus two steel exhaust valves. The weight-optimised valve train ensures low friction and therefore both improved performance and reduced engine braking.
PISTON
The lightweight, forged piston with a box-in-box design is equipped with the high-performance piston rings of the 450 SX-F. The benefit is minimum oil consumption and top performance.
CRANKSHAFT
The crankshaft with 72 mm stroke and ultra-light connecting rod is manufactured by Pankl from a special, high quality steel. As on the other 4-stroke models, it is equipped with a plain bearing in the lower conrod eye. Two press-fit bearing shells run directly on the crank pin. The engine's direct pressure lubrication system ensures the necessary oil supply for this bearing. This design improves the durability of the engine, thereby enabling an extension to the service intervals for the crankshaft, a benefit for the customer in terms of time, effort and cost.
ENGINE MANAGEMENT SYSTEM (EMS)
The engine management system (EMS) from Keihin, with electronic fuel injection and 42 mm throttle body, ensures spontaneous responsiveness and maximum engine performance. An oil-cooled, 196 W alternator provides sufficient power for the fuel injection system, lights and other electrical loads. Various engine characteristics can be selected via the EMS, with a map-select switch available as a PowerPart. Furthermore, a user-setting tool (also available as an option) allows data to be read from the bike by laptop and the mapping, ignition and fuel injection to be modified in a matter of a few mouse clicks. |
