Procom Voltage Regulators & Rectifiers: Reliable Charging for Powersports
When your powersports vehicle's charging system starts acting up — dead batteries, flickering lights, or unreliable starts — the culprit is often a failing voltage regulator/rectifier. Procom Engineering, a California-based manufacturer known throughout the powersports world, has built a strong reputation by delivering dependable, OEM-quality electrical components for a remarkably wide range of machines. Their lineup of voltage regulators is among the most comprehensive available for street bikes, sport bikes, ATVs, and cruisers alike.
The Procom ESR Series: Coverage Across Major Brands
Procom's voltage regulator/rectifier products are sold under the ESR (ElectroSport Regulator) series, a line engineered to provide broad fitment across many of the most popular powersports makes and models. Whether you ride a Ducati, Honda, Suzuki, Yamaha, or Kawasaki, there's a high likelihood Procom has a direct-replacement unit for your machine. Notable examples include:
- ESR515 & ESR532 — Direct-fit replacements for Ducati models, including the Monster, Multistrada, and Sport 1000 S series
- ESR124 — Engineered for Suzuki SV650, SV1000, and DL650 V-Strom riders
- ESR574 — Covers Suzuki LT-A/LT-F500 ATVs from 1998–2002
- ESR125 — A drop-in fit for the Honda TRX300FW (1988–1991)
- ESR644 — Designed for Yamaha ATV applications
- ESR840 — Built for the Kawasaki ZX-9R Ninja (1998–1999)

This breadth of coverage reflects Procom's commitment to serving riders across the full spectrum of powersports, from vintage ATVs to modern sport bikes.
What Sets Procom Regulators Apart
Procom's ESR-series units are engineered as better-than-OEM replacements, not just like-for-like substitutes. Each unit uses the latest regulation circuitry for optimum system voltage, and is manufactured with modern, high-grade components for reliable performance over time. Units are designed to regulate output to a consistent 14.3V DC — the optimal range for battery charging and accessory power without risk of overcharging sensitive electronics. Construction features include anodized cast aluminum housings with potted internal components for added protection against heat, vibration, and moisture — conditions that are par for the course in off-road and high-performance riding environments.
Every Procom voltage regulator/rectifier comes backed by a full one-year manufacturer's warranty, giving riders confidence that they're investing in a component built to last. And because these units are designed as plug-in replacements, installation is straightforward for experienced home mechanics and shop technicians alike.
Why the Voltage Regulator Matters
The regulator/rectifier is the cornerstone of any powersports charging system. It converts the alternating current (AC) generated by the stator into the direct current (DC) needed by your battery and accessories, while simultaneously clamping voltage to safe levels to prevent damage to lights, instruments, and electronics. A failing unit can cause a cascade of electrical problems, making a quality replacement critical — not optional.
Procom's deep catalog of over 40 voltage regulator SKUs means that whether you're restoring a classic ATV or maintaining a modern sport bike, you can find the right fitment without compromise.
