- Dirt Bike
The KTM 500 EXC-F is the strongest dual sport bike in the world, although that doesn t mean it s hard to control. This motorcycle is as lean and civilized as a thoroughbred race horse. But let it rip, and its 4-stroke SOHC engine blasts the cutting-edge chassis across any terrain you choose. Ahead of the competition. No sweat, just glory.Features may include:
Small in dimensions, sky-high on output. The KTM 500 EXC-F s fuel-injected powerhouse makes it the most compact and lightest 500 on the market, while delivering groundbreaking torque and power figures over the entire rev range thanks to a single overhead camshaft cylinder head and the latest electronic fuel injection. Class-leading and cutting-edge: just the way we like it.
- CYLINDER HEAD
A single overhead camshaft controls intake and exhaust through optimized ports, while a cutting-edge combustion chamber and water jacket create mind-blowing power while managing heat. The engine s four valves rely on extremely rigid rocker arms. Double lateral brackets fix the engine to the frame and reduce vibrations.
The KTM 500 EXC-F s crankshaft utilizes a short connecting rod, which makes for an overall compact and lightweight engine with a snappy power delivery. A plain big (bottom) end bearing with two force-fitted bearing shells runs directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine s pressurized lubrication. This design is a decisive benefit in terms of the crankshaft service interval, which can be lengthened due to the plain bearing. So just pin it, all day long.
The reliable 6-speed transmission features a special surface treatment on the 2nd, 3rd and 4th gears for solid reliability. The advanced īNo Dirtī gear shift lever design prevents dirt from jamming the joint of the lever and guarantees precise shifting even in the muddiest conditions. For 2018 the transmission shaft gets a new bearing that has a bigger overlap in the cases. This means reliability even under extremely hard conditions. Think GP-level riding. In knee-deep sand. And a new, stronger shifting star made of MIM steel (metal injected molding) improves reliability even further.
- CRANKCASES AND ENGINE COVERS
The design of the die-cast crankcases allows for minimal weight and a very centralized shaft configuration. This makes the engine short and compact, while contributing to an efficient centralization of masses. The engine covers also feature a solid surface structure, which reduces the wear caused by the rider s boots. This way, your EXC-F will keep looking better longer.
The KTM 500 EXC-F is fitted with a unique E-starter as standard, which is a clear advantage when it comes to crunch time in the heat of ba
