This genuine OEM Top-End Gasket Kit is essential for maintaining the engine integrity of your 2-stroke motorcycle. It includes all necessary seals, O-rings, and various thicknesses of cylinder base gaskets to ensure a perfect seal and correct squish clearance during a top-end rebuild. Using original equipment manufacturer parts guarantees precise fitment and reliable performance under high-stress racing conditions.

This kit is compatible with a wide range of 250cc and 300cc TBI models from 2023 to 2026. It fits KTM 250/300 SX, XC, XC-W, and EXC models, including Six Days, Champion Edition, and Hardenduro versions. It also supports Husqvarna TC 250/300, TE 250/300, and TX 300 models, as well as GasGas MC 250/300, EC 250/300, and EX 250/300 series across the 2023, 2024, 2025, and 2026 model years.

The kit features multiple base gaskets ranging from 0.20mm to 0.70mm, allowing for fine-tuning of the engine's compression and port timing. High-quality Viton O-rings for the cylinder head and durable copper washers for the head bolts are included to prevent coolant leaks and pressure loss. These components are specifically designed to withstand the extreme temperatures and pressures of modern fuel-injected 2-stroke engines.

When installing this gasket set, ensure all mating surfaces are thoroughly cleaned and free of old gasket residue. It is recommended to measure the piston-to-head clearance to select the appropriate base gasket thickness for your specific engine setup. Always follow the manufacturer's torque specifications for cylinder head bolts to ensure an even and secure seal.
