Gaskets are essential for ensuring fluids (oil, fuel, and coolant) are sealed and compressed within the engine. They're found in numerous places on motorcycles and scooters, and choosing the right one is essential to avoid leaks and breakages.

🧱 Types of Motorcycle and Scooter Gaskets

🔧 1. Engine Gaskets

1. Cylinder head 🧠

It ensures the seal between the cylinder and the head → prevents compression or coolant leaks.

2. Cylinder base

Mounted between the cylinder and the engine crankcase .

3. Engine cover / crankcase closure

Essential for oil sealing and to prevent air leaks.

4. Water pump / thermostat (in liquid engines)

5. Valve cover (4-stroke motorcycles)

🔩 2. Variator and Clutch Gaskets (Scooter)

1. Transmission cover
Prevent dust or water from entering the variator assembly.

2. Clutch cover gaskets

🧰 3. Oil seals and O-rings

Often used in conjunction with gaskets:

• Crankshaft oil seals → essential in 2T engines
• O-rings for oil pumps, thermostats, oil filters, through bolts

🧪 Common Materials

1. PAPER Economical, easy to cut, disposable
2. METAL/COMPOSITE For high pressure (head gaskets)
3. Flexible RUBBER/NBR/Viton , for oil lids and caps
4. O-RING Circular rubber seal
