Description

The GD250 engine is a high-revving thumper. When performing essential maintenance like replacing pistons, valves, or the tensioner mechanism itself, this gasket must be replaced to maintain an airtight and oil-tight seal. We use materials designed for performance and longevity, justifying a premium price by preventing catastrophic engine damage that a cheap, failing seal could cause. Since many major GD250 internal parts are no longer in production, doing the job right the first time is crucial.

💎 Precision Engineering for Peace of Mind

Every seal matters in a performance engine. Ensure your rebuild is secure with components designed for durability.

Precision Cut Guaranteed perfect fitment.	High Temp Material Withstands engine heat cycle.
Oil Pressure Safe Prevents costly oil leaks.	Vital Maintenance Required for top-end rebuilds.

📜 Confirmed Fitment Guide

✅ FITS: GD250R (Full Fairing) and GD250N (Naked/Exiv).
📅 YEARS: All model years from 2013 through to 2020.
❌ WILL NOT FIT: GT125/250/650 V-Twin engines (different gasket shape).

💡 RECOMMENDED PAIRING:

🔧 Install Tips

Timing Marks: Always verify your cam timing alignment marks are correct before reassembling and starting the engine.
Torque Carefully: Use the manufacturer-specified torque settings for the housing bolts to avoid crushing the new gasket or stripping threads in the cylinder head.
