Honda Grom Bore Kit: Upgrading Your Engine for Maximum Speed

This is the biggest big bore kit on the market for your Honda Grom & Monkey 125! This kit features an aluminum ceramic coated cylinder. This ceramic coating is lighter than steel-sleeved aluminum, reduces friction (increasing power), improves sealing, and provides better heat transfer so your engine runs and cools down quicker. This kit requires no machining of the cases and does not require a different head. It is recommended that a professional install this kit. It is also recommended to use a fuel controller and oil cooler to prevent lean conditions which may damage your engine.
