The Honda CT70, a classic mini bike, is known for its reliability and versatility. However, one crucial aspect of maintaining its performance involves ensuring proper tire pressure. Incorrect tire pressure can lead to poor handling, reduced fuel efficiency, and even tire damage. Understanding the correct tire pressure for your specific model is essential for safe and enjoyable riding.

Maintaining the right tire pressure is not just about performance; it’s also about safety. Riding on under-inflated or over-inflated tires can cause accidents and increase the wear and tear on your bike. The Honda CT70 comes in various trims and engine configurations, each with specific tire pressure requirements. Below is a detailed table that outlines the recommended tire pressure for different trims and engines of the Honda CT70.

Honda CT70 Tire Pressure Sensor Reset

The tire pressure monitoring system (TPMS) in the Honda CT70 is designed to alert you when tire pressure is low or if there’s a malfunction. If the TPMS light is flashing, it indicates an issue that requires attention. Resetting the tire pressure sensor is a straightforward process, but it’s essential to follow the correct steps to ensure it functions properly.

Steps to Reset the Tire Pressure Sensor

  1. Check Tire Pressure: Before resetting the sensor, ensure that all tires are inflated to the recommended pressure.
  2. Turn on the Ignition: Insert the key into the ignition and turn it to the “On” position without starting the engine.
  3. Locate the TPMS Reset Button: The reset button is usually found under the steering wheel or on the dashboard. Refer to your owner’s manual for the exact location.
  4. Press and Hold the Reset Button: Press and hold the TPMS reset button until the TPMS light blinks three times, then release it.
  5. Start the Engine: Turn the ignition to the “Off” position and then start the engine. The TPMS light should turn off after a few minutes.

Common Reasons for TPMS Light Flashing

The TPMS light may flash for several reasons. Understanding these can help you diagnose the issue effectively.

Issue Description
Low Tire Pressure One or more tires are below the recommended pressure, triggering the warning light.
Faulty Sensor The tire pressure sensor may be malfunctioning or damaged.
Battery Issues The battery in the tire pressure sensor may be dead, requiring replacement.
Temperature Changes Significant temperature fluctuations can affect tire pressure, causing the light to flash.

Additional Tips


  • Regularly check tire pressure, especially before long rides.

  • Keep a tire pressure gauge handy to monitor pressure accurately.

  • Consult a professional mechanic if the TPMS light continues to flash after resetting.

Importance of Maintaining Proper Tire Pressure

Maintaining proper tire pressure is crucial for the overall performance and safety of your Honda CT70. Incorrect tire pressure can lead to various issues, including poor handling, increased tire wear, and reduced fuel efficiency. Under-inflated tires can cause excessive heat buildup, leading to tire blowouts, while over-inflated tires can result in a harsh ride and decreased traction. Regularly checking and maintaining the correct tire pressure ensures a smoother, safer ride.

Additionally, proper tire pressure affects the bike’s braking distance and cornering stability. When tires are inflated to the recommended levels, they provide optimal contact with the road, allowing for better grip and control. This is especially important in varying weather conditions, where tire performance can significantly impact safety.

How to Check Tire Pressure

Checking the tire pressure on your Honda CT70 is a straightforward process. Follow these steps to ensure accuracy:

  1. Gather Necessary Tools: You will need a reliable tire pressure gauge. Digital gauges are often more accurate than manual ones.
  2. Remove Valve Caps: Unscrew the valve caps from each tire to access the valve stems.
  3. Press the Gauge: Firmly press the tire pressure gauge onto the valve stem. Make sure there are no hissing sounds, which indicate air escaping.
  4. Read the Pressure: Check the reading on the gauge. Compare it to the recommended tire pressure found in your owner’s manual or on the tire itself.
  5. Adjust as Needed: If the pressure is too low, add air until it reaches the recommended level. If it’s too high, release some air until the correct pressure is achieved.
  6. Replace Valve Caps: Once done, screw the valve caps back on to protect the valve stems.

Useful Tips for Tire Pressure Maintenance

To ensure your Honda CT70 remains in optimal condition, consider the following tips:


  • Check Regularly: Inspect tire pressure at least once a month and before long trips.

  • Monitor Temperature Changes: Tire pressure can fluctuate with temperature changes. Check pressure during extreme weather conditions.

  • Use a Quality Gauge: Invest in a good-quality tire pressure gauge for accurate readings.

  • Inspect Tires for Damage: Regularly check for signs of wear, cracks, or punctures that could affect tire pressure.

  • Be Mindful of Load: Carrying extra weight can affect tire pressure. Adjust accordingly if you plan to carry additional cargo.

By following these guidelines, you can maintain proper tire pressure, ensuring a safer and more enjoyable riding experience on your Honda CT70.
