§ 02 / About this part
What it is
The WOSSNER PSTN KT YAM YZ250F STD B, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This forged top-end kit is sized for YZ250F cylinders that have seen significant use. The Standard B diameter accounts for natural bore wear to maintain the correct piston-to-wall clearance. It is a vital replacement part for restoring engine efficiency and compression. The kit includes the piston, rings, gudgeon pin, and circlips. Measure your cylinder accurately to confirm this size is required. During the rebuild, seat the circlips firmly in their grooves to prevent failure. Verify the ring end gap against the workshop manual. Proper lubrication during assembly is essential for a successful break-in period.
