The recommended oil type for the Yamaha WR250R 2020 is SAE 10W-40 with an oil capacity of 1.4 liters (1.48 US qt) during an oil change.
The air filter should be inspected and cleaned every 3,000 km (1,900 miles) or more frequently if riding in dusty conditions.
The recommended tire pressure for the WR250R 2020 is 22 psi (150 kPa) for the front tire and 25 psi (175 kPa) for the rear tire.
To adjust the suspension for off-road use, increase the rear shock preload and adjust the rebound damping to suit rougher terrain for better stability and comfort.
If the bike won't start, check the battery charge, ensure the kill switch is in the run position, inspect the fuel supply, and check the spark plug for wear or damage.
Clean and lubricate the chain every 500 km (300 miles) or after riding in wet or dusty conditions. Adjust the chain tension to maintain 30-40 mm (1.2-1.6 inches) of slack.
Use a high-quality ethylene glycol-based antifreeze coolant for the WR250R 2020, mixed with distilled water at a 1:1 ratio for optimal performance.
To improve fuel efficiency, ensure regular maintenance, keep the tires properly inflated, avoid excessive idling, and use smooth throttle control.
First, remove the caliper from the fork leg, then take out the old pads. Insert new brake pads, ensuring they are properly seated, and reattach the caliper. Test the brakes before riding.
To set the correct sag, measure the bike's height without load, then with the rider seated. Adjust the rear shock preload until the sag is between 90-100 mm (3.5-3.9 inches).
