TECNIUM Top End Gasket Set for KTM EXC 250, EXC 300, SX 250 2003-2007

TECNIUM offers this top-end gasket kit for KTM EXC 250, EXC 300, SX 250 2003-2007. The top end is the cylinder, piston and cylinder head. When they are taken apart, the gaskets sealing them are crushed and cannot be reused.

Why buy a complete kit?

The benefits:

• Every top-end gasket in one part number: nothing is forgotten at reassembly.
• Cheaper than buying the gaskets one by one.
• New gaskets guarantee compression and sealing against water, oil and gases.

When should you replace the gaskets on your KTM EXC 300?

An oil or coolant leak, seepage around the cases or a loss of compression signal a tired gasket. Having the kit to hand means the bike is never stuck waiting for one missing gasket.

No manufacturer hour figure for this model. Cross-Mania guideline: compression check every 20 h in hard use and every 40 h for leisure.
