Features:
This is a pure off-road/enduro motorcycle. It does not feature infotainment systems like car stereos or navigation. Rider interface is limited to essential controls and indicators.
Features:
No electronic driver assistance systems (e.g., ABS, traction control) are typically present on this 2012 model, as it is designed for closed-course competition or off-road use where such systems are not standard.
Features:
No Bluetooth or smartphone connectivity features.
Efi System:
Electronic Fuel Injection system managed by an ECU for optimal fuel delivery and ignition timing based on engine load and RPM, contributing to performance and emissions control.
Oil Change Interval:
Every 15 operating hours or annually. Frequent oil changes are crucial for engine longevity.
Air Filter Cleaning:
Every 5-10 operating hours, depending on dust conditions. Critical for preventing engine wear.
Valve Clearance Check:
Every 20-30 operating hours, or as specified in the manual. Critical for maintaining engine performance.
Chain Lubrication:
Every 5-10 operating hours, or after washing/riding in wet conditions.
Engine Oil Capacity:
Approx. 1.1 liters (1.16 US quarts) for oil change; 1.3 liters (1.37 US quarts) for complete overhaul (refer to manual for precise figures).
Fork Oil Type:
WP Suspension recommends specific WP suspension fluids or equivalent high-quality fork oil (e.g., Motul Factory Line). Viscosity and fill level are critical and detailed in the manual.
Brake Fluid Type:
DOT 4 hydraulic brake fluid.
Common Wear Items:
Clutch plates, brake pads, wheel bearings, steering head bearings, linkage bearings, piston rings, valve seals. These are typical wear items for high-performance off-road motorcycles.
Potential Engine Concerns:
Early models of high-performance 350cc engines, while powerful, can be sensitive to maintenance intervals. Consistent adherence to oil changes, air filter cleaning, and proper coolant levels is vital to prevent premature wear on components like camshafts and valves.
