Honda CBR650R - Owner's Manual > Catalytic Converter

Information, Specifications / Catalytic Converter

This motorcycle is equipped with a three-way catalytic converter. The catalytic converter contain precious metals that serve as catalysts in high temperature chemical reactions that convert hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NOx) in the exhaust gasses into safe compounds.

A defective catalytic converter contributes to air pollution and can impair your engine's performance. A replacement unit must be an original Honda part or equivalent.

Follow these guidelines to protect your motorcycle's catalytic converter.

  • Always use unleaded petrol. Leaded petrol will damage the catalytic converter.
  • Keep the engine in good running condition.
  • Have your motorcycle serviced if your engine is misfiring, backfiring, stalling, or otherwise not running properly, stop riding and turn off the engine.

Caring for Your Motorcycle

Frequent cleaning and polishing is important to ensure the long life of your Honda. A clean motorcycle makes it easier to spot potential problems.

In particular, seawater and salts used to prevent ice on roads promote the formation of corrosion. Always wash your motorcycle thoroughly after riding on coastal or treated roads.


Allow the engine, muffler, brakes, and other high-temperature parts to cool before washing.

1. Rinse your motorcycle thoroughly using a garden hose to remove loose dirt.

2. If necessary, use a sponge or a soft towel with mild cleaner to remove road grime.

  • Clean the windscreen, headlight lens, panels, and other plastic components with extra care to avoid scratching them. Avoid directing water into the air cleaner, muffler, and electrical parts.

3. Thoroughly rinse your motorcycle with plenty of clean water and dry with a soft, clean cloth.

4. After the motorcycle dries, lubricate any moving parts.

  • Make sure that no lubricant spills onto the brakes or tyres. Brake discs or pads contaminated with oil suffer greatly reduced braking effectiveness and can lead to a crash.

5. Lubricate the drive chain immediately after washing and drying the motorcycle.

6. Apply a coat of wax to prevent corrosion.

  • Avoid products that contain harsh detergents or chemical solvents. These can damage the metal, paint, and plastic on your motorcycle.

    Keep the wax clear of the tyres and brakes.

  • If your motorcycle has any mat painted parts, do not apply a coat of wax to the mat painted surface.

 Washing Precautions

Follow these guidelines when washing:

  • Do not use high-pressure washers:
    • High-pressure water cleaners can damage moving parts and electrical parts, rendering them inoperable.
  • Do not direct water at the muffler:
    • Water in the muffler can prevent starting and causes rust in the muffler.
  • Dry the brakes:
    • Water adversely affects braking effectiveness. After washing, apply the brakes intermittently at low speed to help dry them.
  • Do not direct water under the seat:
    • Water in the underseat compartment can damage your documents and other belongings.
  • Do not direct water at the air cleaner:
    • Water in the air cleaner can prevent the engine from starting.
  • Do not direct water near the headlight:
    • Any condensation inside the headlight should dissipate after a few minutes of running the engine.
  • Do not use waxes containing compounds at the mat painted surface:
    • Using plenty of water, clean the mat painted surface with a soft cloth or sponge. Dry with a soft, clean cloth.
    • Use neutral detergent to clean mat painted surface.

Aluminium Components

Aluminium will corrode from contact with dirt, mud, or road salt. Clean aluminium parts regularly and follow these guidelines to avoid scratches:

  • Do not use stiff brushes, steel wool, or cleaners containing abrasives.
  • Avoid riding over or scraping against curbs.


Follow these guidelines to prevent scratches and blemishes:

  • Wash gently using a soft sponge and plenty of water.
  • To remove stubborn stains, use diluted detergent and rinse thoroughly with plenty of water.
  • Avoid getting petrol, brake fluid, or detergents on the instruments, panels, or headlight.


Using plenty of water, clean the windscreen with a soft cloth or sponge. (Avoid using detergents or any kind of chemical cleaner on the windscreen.) Dry with a soft, clean cloth.

NOTICE To avoid possible scratching or other damage, use only water and a soft cloth or sponge to clean the windscreen.

For a dirtier windscreen, use a diluted neutral detergent with a sponge and plenty of water.

Make sure to wash off all the detergent.

(Detergent residue may cause windscreen cracks.) Replace the windscreen if scratches cannot be removed and they obstruct clear vision.

Take care to keep battery electrolyte, brake fluid, or other chemical solvents off the windscreen and screen garnish. They will damage the plastic.

Exhaust Pipe and Muffler

The exhaust pipe and muffler are stainless steel but may become stained by mud or dust.

To remove mud or dust, use a wet sponge and a liquid kitchen abrasive, then rinse well with clean water. Dry with chamois or a soft towel.

If necessary, remove heat stains by using a commercially available fine texture compound.

Then rinse by the same manner as removing mud or dust.

When the exhaust pipe and muffler are painted, do not use a commercially available abrasive kitchen cleaning compound. Use a neutral detergent to clean the painted surface on the exhaust pipe and muffler. If you are not sure if your exhaust pipe and muffler are painted, contact your dealer.

NOTICE Even though the exhaust is made of stainless steel, it can become stained. Remove all marks and blemishes as soon as they are noticed.

Storing Your Motorcycle

If you store your motorcycle outdoors, you should consider using a full-body motorcycle cover.

If you won't be riding for an extended period, follow these guidelines:

  • Wash your motorcycle and wax all painted surfaces (except mat painted surfaces).

    Coat chrome pieces with rust-inhibiting oil.

  • Lubricate the drive chain.
  • Place your motorcycle on a maintenance stand and position a block so that both tyres are off the ground.
  • After rain, remove the body cover and allow the motorcycle to dry.
  • Remove the battery to prevent discharge.

    Charge the battery in a shaded, well-ventilated area.

    • If you leave the battery in place, disconnect the negative - terminal to prevent discharge.

After removing your motorcycle from storage, inspect all maintenance items required by the Maintenance Schedule.

Transporting Your Motorcycle

If your motorcycle needs to be transported, it should be carried on a motorcycle trailer or a flatbed truck or trailer that has a loading ramp or lifting platform, and motorcycle tie-down straps. Never try to tow your motorcycle with a wheel or wheels on the ground.

NOTICE Towing your motorcycle can cause serious damage to the transmission.

You & the Environment

Owning and riding a motorcycle can be enjoyable, but you must do your part to protect the environment.

Choose Sensible Cleaners

Use a biodegradable detergent when you wash your motorcycle. Avoid aerosol spray cleaners that contain chlorofluorocarbons (CFCs) which damage the atmosphere's protective ozone layer.

Recycle Wastes

Put oil and other toxic wastes in approved containers and take them to a recycling centre.

Call your local or state office of public works or environmental services to find a recycling centre in your area, and to get instructions on how to dispose of non-recyclable wastes. Do not place used engine oil in the trash, or pour it down a drain or on the ground. Used oil, petrol, coolant, and cleaning solvents contain poisons that can hurt refuse workers and contaminate drinking water, lakes, rivers, and oceans.

Serial Numbers

The frame and engine serial numbers uniquely identify your motorcycle and are required in order to register your motorcycle. They may also be required when ordering replacement parts.

The frame number is stamped on the right side of the steering head.

The engine number is stamped on top of the crankcase.

You should record these numbers and keep them in a safe place.
