Yamaha TT-R230 v4 2019 Owner's Manual

The recommended oil for the Yamaha TT-R230 2019 is Yamalube 10W-40 or any equivalent motor oil that meets the API service classifications of SG or higher.
The air filter should be cleaned every 20-30 hours of riding, or more frequently if you ride in dusty or muddy conditions.
The recommended tire pressure for the Yamaha TT-R230 2019 is 15 psi for both the front and rear tires.
To adjust the chain tension, place the bike on a stand, loosen the axle nut, and turn the chain adjusters evenly on both sides until the chain has about 1.2 inches (30 mm) of slack. Tighten the axle nut to secure.
If your Yamaha TT-R230 2019 won't start, check the fuel level, ensure the kill switch is in the "run" position, inspect the spark plug for fouling, and verify battery charge. If the issue persists, consult a professional mechanic.
If the bike overheats, stop riding immediately, let the engine cool down in a shaded area, and check the coolant level. Ensure there are no obstructions in the radiator and the fan is functioning properly.
The spark plug should be inspected every 600 miles (1,000 km) and replaced as necessary, typically every 3,000 miles (5,000 km) or annually.
Regularly inspect brake pads for wear, replace them if the thickness is less than 1 mm, and clean brake components to prevent dirt buildup. Check for proper brake fluid levels and replace every two years.
For off-season storage, clean the bike thoroughly, change the oil, fill the fuel tank with a stabilizer, disconnect the battery, and store the bike in a dry, covered place. Elevate the bike to prevent tire deformation.
Adjust the suspension settings according to your weight and riding style. For a softer feel, reduce the preload on the shock absorber; for a firmer suspension, increase it. Always make adjustments in small increments and test ride.
