§ 02 / About this part
What it is
The VERTEX PISTON KIT TOP END Ø 39.50 EF, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This EF-size kit is for cylinders with significant wear or those replated to specific oversize tolerances. It restores the critical seal required for efficient combustion. Neglecting your top-end leads to lost compression and potential engine failure. This kit provides the piston, rings, gudgeon pin, and circlips. Precise measurement of your bore is mandatory before selecting this size. During installation, ensure the circlips are seated fully in their grooves. Proper heat cycles are required to bed in the rings and ensure the long-term durability of your engine.
