§ 02 / About this part
What it is
The VERTEX PISTON KIT PRO REPLICA Ø 100.00 STD, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.
Refresh your top-end to maintain the torque and reliability of your large-bore engine. This kit sits in the cylinder and is responsible for converting combustion into drive. Four-stroke pistons face significant stress, and worn rings will eventually lead to oil burning and lost power. This standard-size kit matches the factory bore dimensions for a direct replacement. It includes the piston, rings, gudgeon pin, and circlips. Confirm your cylinder is within tolerance using a bore gauge before installation. Always check ring end gap and ensure the piston is oriented correctly to prevent engine damage.
