§ 02 / About this part
What it is
The WOSSNER PISTON KIT STD 250 SE-F SE-R 08-13 77.94 A, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
This forged piston kit is the core of your top-end rebuild. It sits inside the cylinder bore and handles high-revving four-stroke loads. Replace your piston when you reach the service hour limit to maintain peak compression. This A-size fitment is for fresh cylinders or those with minimal wear. Always measure your bore with a dial gauge to verify the required clearance. Check your ring end gap before fitting. Ensure the arrow on the crown points toward the exhaust port. The kit includes the piston, rings, gudgeon pin, and circlips. Lubricate the small-end bearing during assembly.
