§ 02 / About this part
What it is
The WOSSNER PISTON KIT STD 250 SE-F SE-R 08-13 77.95 B, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This forged component sits at the heart of your top-end rebuild. It replaces the factory unit to restore lost compression and engine response. Over time, the skirt wears and tolerances widen, leading to piston slap or catastrophic failure. This B-size kit is designed for cylinders with slight wear beyond the initial A-spec. Ensure you measure your bore accurately with a dial bore gauge before installation. The kit includes the piston, rings, gudgeon pin, and circlips. Always check your ring end gap and verify the arrow points toward the exhaust port during assembly.
