The Kawasaki KLE 500 SE holds a unique place in motorcycling history as one of the few dual-sport machines to repurpose a high-revving sportbike heart. While most competitors opted for large-displacement singles (thumpers), Kawasaki utilized the liquid-cooled parallel-twin engine from the GPZ 500 S. However, to suit the adventure-touring role, engineers specifically detuned the unit with revised cam profiles and smaller carburetors, shifting the powerband to favor mid-range tractability over the GPZ’s top-end scream—an engineering choice that granted the KLE a remarkably smooth character on both tarmac and gravel.
Technical Review: The Versatile Parallel Twin
At the core of the KLE500SE/26 is a 498cc DOHC engine. Unlike contemporary singles, the parallel-twin configuration offers significantly reduced vibration at highway speeds, making it a superior long-distance commuter. The chassis features a high-mounted exhaust and a bash plate, signaling its off-road aspirations, though the soft suspension tuning clearly prioritizes comfort and light trail work over aggressive enduro riding.
Maintenance Guide
1. Lubrication System
For optimal engine longevity and wet-clutch performance, use 3.0 liters of SAE 10W-40 oil. It is critical to select an oil that meets JASO MA standards to prevent clutch slippage. Given the engine’s lineage, maintaining clean oil is paramount for the health of the cam chain tensioner.
2. Tires and Handling
The KLE 500 SE utilizes a classic 21-inch front and 17-inch rear wheel combination, providing a wide array of tire choices from 50/50 dual-sport rubber to street-biased adventure tires. For standard road use, maintain 1.5 bar (21 psi) in the front and 2.0 bar (28 psi) in the rear. Lowering these slightly for off-road sections can improve traction, but be wary of rim damage due to the bike’s weight.
3. Ignition and Electrical
The electrical system is supported by a YTX12-BS battery. For ignition, the NGK DR9EA is the standard specification. Ensure the electrode gap is precisely set between 0.6–0.7 mm. Fouled plugs are often a sign of the carburetors running too rich, a common trait if the air filter is neglected.
Conclusion
The Kawasaki KLE 500 SE remains a cult favorite for those seeking a reliable, low-maintenance adventure bike that can handle daily duties and weekend explorations with equal poise. By following these technical specifications, owners can ensure the ‘SE’ variant remains a staple of their garage for decades.
