The Honda NX400, a popular dual-sport motorcycle, requires specific parts for maintenance and repair. One crucial component is the rear wheel hub. Knowing the correct size is essential for ordering replacement parts or upgrading your wheels. Unfortunately, there isn't a single, universally stated "rear wheel hub size" for the NX400 because the measurement you need depends on what aspect of the hub you're measuring. This guide will clarify the different measurements and help you find the information you need.
What Measurements Are Important for a Honda NX400 Rear Wheel Hub?
When searching for information about your Honda NX400 rear wheel hub size, you'll find that it's not as simple as a single number. Several dimensions are important, depending on your needs:
1. Axle Shaft Diameter:
This is the diameter of the axle that passes through the hub. This is crucial when choosing a new axle or wheel. You'll need to measure this directly on your motorcycle or consult your owner's manual. This measurement is usually given in millimeters (mm).
2. Hub Flange Diameter:
This refers to the diameter of the outer part of the hub where the spokes attach. It impacts the selection of wheels and sprockets. Again, this needs to be measured or found in a detailed parts diagram.
3. Wheel Bearing Size:
The wheel bearings are crucial for the smooth operation of the wheel. Their size is critical when replacing them. This isn't usually described as a "hub size" but is critical information for ordering replacement bearings. Check your owner's manual or a parts fiche for the correct bearing numbers.
4. Overall Hub Width (or distance between flanges):
This measurement is the distance between the two flanges of the hub. It’s another key dimension to consider when selecting replacement wheels.
How to Find the Correct Dimensions for Your Honda NX400 Rear Wheel Hub
Several reliable methods can help you determine the exact measurements for your Honda NX400's rear wheel hub:
- Consult your owner's manual: The owner's manual should contain detailed specifications, including diagrams and part numbers.
- Use a parts fiche (parts diagram): Online motorcycle parts websites (like those affiliated with dealerships) often provide detailed parts diagrams for specific Honda NX400 models and years. These diagrams usually list dimensions for individual parts.
- Measure directly: Carefully measure the relevant dimensions of your existing hub using a caliper or ruler. Be precise in your measurements.
- Contact a Honda dealership or motorcycle mechanic: Dealerships and experienced mechanics possess the knowledge and resources to identify the correct specifications.
What Year is Your Honda NX400?
The exact specifications can vary slightly depending on the year of manufacture of your Honda NX400. Always specify the year when contacting a parts supplier or mechanic. Minor variations between model years could mean different hub dimensions.
Beyond Simple Dimensions: Understanding Wheel Compatibility
Beyond the direct hub measurements, you need to ensure compatibility with the rest of your wheel assembly. This includes the sprocket, brake rotor, and tire size. Always verify compatibility before purchasing replacement parts.
This comprehensive guide provides various ways to find the specific dimensions you need. Remember that precision is critical when dealing with motorcycle parts. Don't hesitate to consult a professional if you're unsure about any measurements. Accurate information ensures a safe and efficient repair or upgrade.
