Measuring Motorcycle Tires Clearance
Properly measuring the clearance of tires on a motorcycle is crucial for ensuring compatibility, safety, and performance. Here’s a step-by-step process to measure clearance effectively.
Preparation
Before measuring, gather the necessary tools:
- Tape Measure: A flexible tape measure will be more versatile for various components.
- Pencil and Paper: For jotting down measurements.
- Safety Equipment: Ensure to wear gloves and safety glasses while working around your motorcycle.
Measuring Procedure
- Position the Motorcycle: Ensure the bike is on level ground and is upright or on a center stand. This position allows for accurate measurements.
- Measure the Width: To check clearance width, identify the widest parts of the tire near the swingarm and fender. Measure the distance from the tire to the nearest component (like the swingarm) on both sides.
- Measure the Height: Calculate the vertical clearance by measuring the distance between the tire and the fender when the motorcycle is in its standard riding position.
- Check Compression: If applicable, sit on the motorcycle to simulate real conditions and measure again, as weight can compress suspensions and change clearances.
- Record Your Measurements: Write down all measurements for future reference and analysis.
Interpreting Measurements
Once all measurements are taken, evaluate the results to determine if there’s sufficient clearance. Generally, a minimum clearance of about ¼ inch (6mm) is sought to ensure that the tires operate safely without any risk of rubbing against other components.
