OC1 Exhaust Plug

1. Make sure the exhaust system is cold

Always wait until the exhaust pipe has completely cooled down before installing the plug.

2. Insert the plug into the exhaust opening

Gently but firmly insert the OC1 exhaust plug into the opening, pushing it in until you feel resistance.

3. Check the seal tightness

Make sure the plug is properly seated with no gaps through which water or dirt could enter.

4. Proceed with cleaning or storage

Now you can safely wash the motorcycle with a water stream or leave it for long-term storage.

5. Remove the plug before starting the engine

This is critically important — always remove the exhaust plug before starting the engine.

Important

• Never start the engine with the plug installed — this can cause serious damage

• Use only on a cold exhaust system

• Regularly check the rubber condition — replace the plug when signs of wear appear

• Store the plug in a dry place, away from heat sources

Tip

After each use, it's worth cleaning the exhaust plug from dust and dirt to maintain full sealing effectiveness. You can rinse it with warm soapy water and leave to dry. This will extend its lifespan and preserve its sealing properties.

Does the OC1 exhaust plug fit every motorcycle?

The OC1 plug is designed to fit both 2-stroke and 4-stroke engines. Thanks to its tapered design, it adapts to most exhaust pipe diameters. It works with off-road, road, enduro and motocross motorcycles.

How does the rodent protection work?

Rodents often seek shelter in exhaust pipes, especially during winter motorcycle storage. The tight seal created by the OC1 exhaust plug effectively blocks their access to the exhaust system, protecting against damage that could result from their presence.

Can I use the plug for every wash?

Yes! The OC1 exhaust plug is designed for repeated use. Its dense rubber construction is durable and resistant to frequent installation and removal. You can use it for every motorcycle wash without worrying about quick wear.

What happens if I forget to remove the plug before starting the engine?

Starting the engine with the plug installed can cause serious damage to the exhaust system and engine. Blocked exhaust gas flow leads to excessive pressure in the system. That's why always remember to remove the plug before each start — this is a key safety rule.

How do I care for the plug to make it last longer?

After use, rinse the plug with warm water and mild soap, dry it and store in a dry place away from heat sources and direct sunlight. Regularly check the rubber condition — if you notice cracks, loss of elasticity or other signs of wear, replace the exhaust plug with a new one.

Does the plug protect against high-pressure water stream?

Yes, the OC1 exhaust plug creates a tight seal that protects against water even when using a pressure washer. However, always make sure the plug is properly seated before starting to wash.

Can I use the plug during motorcycle storage throughout the winter?

Definitely yes! The OC1 exhaust plug is ideal for long-term storage. It protects the exhaust system from moisture, dust and rodents throughout the entire period when the motorcycle is not in use.

Is the plug material resistant to high temperatures?

The plug is made from high-quality dense rubber that is resistant to typical temperatures encountered during use. However, always install the plug only on a cold exhaust system — never on a hot pipe right after riding.

Do I need special tools to install the plug?

No, installing the OC1 exhaust plug is extremely simple and requires no tools. Just insert it manually into the exhaust opening — the tapered design will make it self-adjust and create a tight seal.
