An aftermarket voltage regulator rectifier for motorcycles, aimed at stabilising charging and reducing electrical interference. Riders who depend on consistent lighting and battery health will gain confidence from robust fitment and watertight construction. Is WOOSTAR Voltage Regulator Rectifier the right replacement for a DR-Z400 series machine?

⚡ At a Glance
  • Output Stability: Three-phase full-wave rectification for stable DC output and reduced interference
  • Best for: Owners of Suzuki DR-Z400S, DRZ400 and DR-Z400SM needing a direct replacement regulator
  • Not ideal for: Motorbikes requiring a different plug layout or non-standard mounting dimensions

Three-phase full-wave design converts AC into steadier DC with higher efficiency. Control voltage is specified at 14.5V ± 0.5V with a working current of 20A.


Steadier charging and lighting – thanks to three-phase full-wave rectification

Three-phase full-wave rectification lengthens conduction time across three AC phases, converting electrical energy into more consistent direct current. The specification notes improved efficiency, stable DC output and stronger anti-interference ability compared with simpler rectifiers.

More consistent charging and steadier lighting under load, reducing flicker and voltage swings during rides. Best for riders who need dependable electrical behaviour on long or rough journeys.

Durable, weatherproof construction – with watertight, vibration-free encapsulation

Encapsulation protects internal components from moisture and vibration, a point highlighted by user feedback describing watertight and vibration-free assembly. Robust packaging reduces the risk of corrosion and mechanical fatigue.

Greater reliability in wet or dusty conditions, extending service life and lowering the chance of roadside electrical failures. Suits riders who use their bikes in mixed weather or off-road.

Straightforward physical fit – with 2+3 male plug and standard mounting dimensions

Physical dimensions are provided as length 75mm, width 48mm and thickness 25mm, with a mounting hole pitch of 60mm and a 2+3 male plug arrangement. The part is offered specifically for DR-Z400S 2000-2009, DRZ400 2000-2012 and DR-Z400SM 2005-2009.

Direct replacement for compatible DR-Z400 variants when model and size match, enabling relatively quick swaps. Always confirm model number and measurements before ordering to ensure compatibility.
