  6. Brake Inspection: Ensure that the brake pads are in good condition and have sufficient thickness. Check the brake fluid level and replace it if it appears dirty or contaminated.
  7. Tire Maintenance: Check the tire pressure regularly and inspect the tires for any signs of damage or excessive wear. Replace tires that are worn beyond the recommended limits.
  8. General Inspections: Routinely inspect the bike for loose bolts, damaged cables, or any other signs of wear and tear. Address any issues promptly to avoid potential problems during rides.

It’s important to note that these are general maintenance guidelines. For detailed instructions and specific maintenance intervals, refer to the Yamaha YZ125 owner’s manual. Following the manufacturer’s recommendations will help ensure the longevity and performance of your Yamaha YZ125.
