Description: This Stator is manufactured with an advanced core made of magnetically highly material to minimize the magnetic losses.It uses the highest quality copper wire for the windings that are installed using computer controlled winding machines for winding quality.Therefore, this stator generates less heat than the unit which dramatically improves reliability and durability. The best quality lead wires with insulation bring both enhanced abrasion and heat resistant, and the rubber seals and to be an exact fit in the bike.Made of High Grade Magnetically Material to Minimize the Magnetic Losses, Computerized Winding to Optimize Quality of Copper Wiring, Generate Less Heat, Improved Heat Sink and Charging CapabilitiesDramatically Improves Reliability and Durability Comparing to Units, Best Quality Lead Wires with Insulation bring Both Enhanced Abrasion and Heat Resistant.Fitment:For 400Notice:Professional Installation is Highly RecommendedMaterial: Metalcolour: As shownPackage Contents:1 x Relay Only the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
