Buying Guide: Key Purchase Considerations
- Tank capacity vs riding range: Choose capacity that aligns with typical ride lengths and tank clearance on your frame.

- Compatibility and mounting: Verify model year compatibility and whether frame modification is required.
- Fitment specifics: Check direct-mount vs universal fit, fuel petcock location, and mounting hardware availability.
- Material and durability: Steel tanks offer dent resistance and durability; raw steel requires sealing or finishing to prevent rust.
