Pulse Adrenaline 125 K157FMI Stator
Replacement stator / magneto generator for Pulse Adrenaline 125 motorcycles using the common K157FMI 18-coil generator.
Product Description
Brand new aftermarket 18-coil stator / magneto generator assembly for compatible K157FMI / Suzuki-GS-pattern 125cc engines. The stator sits inside the flywheel rotor and generates electrical power for the motorcycle's charging and ignition system while the separate magnetic pickup provides the engine-position trigger signal.

Important EFI Version Warning
This listing is for the common 18-coil, 5-wire K157FMI stator pattern. Some later EFI K157FMI motorcycles use a different stator, commonly referenced as 32101QK22000, with a different connector arrangement. Do not order for an EFI model unless the stator, connectors, dimensions and mounting points match.
Before Ordering
- Count the stator coils / poles and compare with the product photographs.
- Measure the outside diameter and centre opening of the original stator.
- Check the three mounting-hole positions and approximately 38 mm mounting-centre spacing.
- Compare the number of wires and both electrical connectors.
- Check the pickup / pulse-sensor position and lead length.
- Where available, compare the original engine code or OE stator number.
Common Symptoms of a Failed Stator
- Battery not charging correctly
- Weak or intermittent spark
- Engine cutting out when hot
- Low or inconsistent AC output from the generator
- Burned, darkened or damaged stator windings
- Melted or overheated charging-system connectors
Installation Advice
Before fitting a replacement stator, check the regulator / rectifier, battery condition, connectors and charging-system wiring. Burned or corroded connectors should be repaired rather than reused. Confirm stator output after installation and route the wiring away from the flywheel, chain, exhaust and other moving or hot components.
Electrical and ignition work should be carried out by a competent motorcycle technician if you are not confident with charging-system diagnosis.
