The Yamaha YZ85 is a motocross bike known for its performance on the track. While the reliability and durability of the YZ85 are generally good, there are certain areas that riders may need to pay attention to for maintenance and potential repairs:
Top-End Rebuild: Due to the high-performance nature of motocross bikes, the top end of the engine (cylinder, piston, and rings) may require more frequent maintenance, especially if the bike is ridden aggressively.
Clutch Wear: Motocross riding on a small displacement bike involves heavy use of the clutch, and this can lead to wear over time. Regularly inspect the clutch plates and springs for signs of wear, and replace them as needed.
Suspension Maintenance: Motocross bikes, including the YZ85, undergo significant stress on the suspension components. Regularly check and maintain the front forks and rear shock for optimal performance.
Air Filter Maintenance: Motocross bikes operate in dusty environments. The air filter can quickly accumulate dirt, so regular cleaning or replacement is crucial to maintaining engine performance.
Exhaust System: Inspect the exhaust system for any damage or leaks. Make sure the silencer and expansion chamber are securely in place and that the silencer packing is in good condition.
Chain and Sprockets: Motocross bikes experience heavy chain stress. Regularly inspect the chain and sprockets for wear, and adjust tension as needed.
Brake System: Check the brake pads, brake fluid levels, and ensure proper brake function. Motocross riding involves frequent braking, so maintaining the braking system is important for rider safety and performance.
Cooling System: Ensure the radiator is clean and free from debris to prevent overheating. Regularly check the coolant level and address any cooling system issues.
Frame and Chassis: Inspect the frame and chassis for any signs of cracks or damage. Regularly check the frame’s integrity to ensure rider safety.
Spark Plug: Check and replace the spark plug as part of routine maintenance. Two stroke bikes tend to be hard on spark plugs because of the oil mixed with the fuel.
Regular maintenance and timely inspections are key to addressing potential issues and ensuring the YZ85 performs well on the motocross track.
