Installation Notes:

These fender mounts are designed to be welded onto your motorcycle frame at the desired mounting location. Proper positioning and alignment are critical for correct fender fitment and appearance. We recommend:

• Test-fit your fender and mounts before welding
• Ensure proper clearance for tire, suspension travel, and chain/belt
• Use appropriate welding techniques for your frame material
• Clean and prep mounting area before welding
• Paint or powder coat after installation to prevent rust

Professional installation is recommended if you're not experienced with welding and frame fabrication. Each TC Bros fender mount is manufactured to exacting standards for reliable performance on your custom motorcycle build.

Premium 1" Motorcycle Throttles for Custom Builds

These high-quality throttle assemblies provide smooth, reliable throttle operation and are available in multiple configurations to match your bike's cable setup and aesthetic preferences.

Available Options:

Cable Type: Single Cable or Dual Cable
Finish: Black or Polished

• Single Cable - Black - Sleek black finish for single cable applications

• Dual Cable (Push-Pull): Uses two cables - one to open the throttle and one to close it. Provides more positive throttle control and is required on many modern motorcycles. Offers smoother operation and better safety.

Black vs. Polished:

• Black: Sleek black finish complements blacked-out builds and contemporary custom motorcycles. Provides a modern, stealthy appearance.
• Polished: Classic polished finish works beautifully with traditional custom builds, cafe racers, and bikes featuring chrome or polished components.

• Matching your bike's color scheme and cable configuration

Installation Notes:

Ensure you select the correct cable type (single or dual) based on your motorcycle's throttle cable configuration. Proper cable routing and adjustment is critical for safe, smooth throttle operation. Professional installation is recommended if you're not experienced with throttle system maintenance.

Important: Always verify your throttle returns to closed position smoothly and completely after installation. Test throttle operation thoroughly before riding.
