Product Information

Full details

This guide is for Honda CB1000R owners (2008-2017) seeking enhanced braking performance and reliability. The TRW Round Floating Brake Disc (MSW240) offers superior stopping power through its high-grade steel rotor and aluminum inner ring, featuring a special ground surface finish. A potential consideration is its specific fitment to the front axle, requiring a matched rear brake system for full benefit.

FAQs

Is this brake disc compatible with models other than the Honda CB1000R (2008-2017)?

No, this specific model (MSW240) is engineered for the front axle of Honda CB1000R motorcycles from 2008 to 2017. Always verify compatibility for your specific motorcycle model and year.

Do I need to replace my brake pads when installing a new disc?

It is strongly recommended to replace your brake pads whenever you install a new brake disc. New pads will conform to the new disc surface more effectively, ensuring optimal performance and preventing premature wear on the new disc.

What is a 'floating' brake disc?

A floating brake disc has two main parts: the rotor (where the pads contact) and an inner carrier or 'hat'. These parts are connected by pins or buttons that allow the rotor to move slightly independently of the carrier. This design helps to compensate for thermal expansion and contraction, preventing the disc from warping under heat.

How do I properly 'bed-in' a new brake disc?

Bedding-in transfers a thin layer of pad material onto the disc surface to ensure optimal friction. Typically, it involves a series of moderate stops from moderate speeds (e.g., 60 mph down to 20 mph) without coming to a complete halt, followed by a period of cooling without heavy braking. Consult the product or motorcycle manufacturer's specific instructions.

Can I use this disc on the rear axle?

No, the TRW MSW240 is specifically designed and specified for the front axle application only.

What material is the brake disc made of?

The disc features a high-grade steel rotor and an aluminum inner ring.

What are the dimensions of the disc?

The outer diameter is 310 mm, the thickness is 5 mm, and the inner diameter is 94 mm.

Troubleshooting

Brake judder or vibration during braking.

This can be caused by uneven pad material transfer, warped rotor, or loose mounting bolts. Ensure the disc is properly seated, all bolts are torqued correctly, and perform a proper brake-in procedure. If vibration persists, the rotor may be damaged or require resurfacing/replacement.

Reduced braking effectiveness or fade.

Check brake fluid level and condition, and inspect brake pads for wear. Ensure the brake system is free of air bubbles. If the disc is very hot, some fade is normal, but persistent fade may indicate an issue with pad material, fluid, or a blocked brake line.

Noise (squealing or grinding) from the brake area.

New pads or discs can sometimes be noisy during the bedding-in process. Grinding typically indicates debris trapped between the pad and rotor, or heavily worn pads. Inspect for foreign objects and ensure pad material is suitable for the disc.

Pros and Cons

Pros

  • Optimized braking performance and feel.
  • Durable construction with high-quality materials.
  • Reduces vibrations for a smoother ride.
  • Floating design prevents warping under heat stress.
  • Perforated surface aids cooling and debris clearance.

Cons

  • Designed exclusively for the front axle.
  • Requires compatible mounting hardware (not always included).
  • Floating discs may require specific bedding-in procedures.
  • Higher cost compared to solid, non-floating discs.

Setup, Compatibility & Care

Compatibility: This TRW Round Floating Brake Disc (MSW240) is specifically designed for the front axle of Honda CB1000R models manufactured between 2008 and 2017. Ensure your motorcycle model and year match these specifications before installation.

Installation:

  1. Ensure the motorcycle is safely supported and the front wheel is removed.
  2. Carefully remove the old brake disc. Note the orientation and any specific spacers or bolts.
  3. Inspect the caliper mounting points and ensure they are clean.
  4. Mount the new TRW floating brake disc. Ensure it is correctly oriented (if applicable) and secured with appropriate fasteners. *Note: It is highly recommended to use new brake disc bolts and torque them to the manufacturer's specifications.* It is also advisable to replace brake pads when installing a new disc.
  5. Allow the disc to 'bed-in' according to TRW or motorcycle manufacturer recommendations, typically involving several moderate stops from increasing speeds without prolonged holding of the brake lever.

Care:

  • Regularly clean the brake disc with a dedicated brake cleaner and a soft cloth. Avoid using abrasive materials that could damage the rotor surface.
  • Inspect the disc for any signs of excessive wear, scoring, or warping during routine maintenance.
  • Ensure brake pads are compatible and not worn down to the backing plate, which can damage the disc.
