High-performance regulator rectifier for the charging system of the Honda CRF250X (2004-2017) / CRF450 / CRF450X (2005-2018) off-road motorcycle.

【Specifically designed for Honda's high-performance off-road vehicles】 This high-performance regulator rectifier was specifically designed for Honda's high-end off-road and long-distance vehicles. It is perfectly compatible with the following models and model years:

Honda CRF250X (Years: 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017)

Honda CRF450 / CRF450X (Years: 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018) Manufactured in strict compliance with the requirements of off-road racing environments and the The original electrical parameters of the vehicle correspond to manufacturer part number SH728AA. It ensures perfect compatibility with the vehicle's three-phase magneto ignition and battery and is an essential upgrade/replacement component that guarantees a stable and reliable charging system even under extreme conditions. 【High-Efficiency Three-Phase Rectification and Competition-Grade Voltage Regulation】 High-efficiency rectification: Efficiently and with minimal loss converts the three-phase AC (AC) generated by the magneto ignition to direct current (DC), thus meeting the high power demands of electronic fuel injection (on some models), ignition, and headlights at sustained high speeds. Precise voltage regulation: Thanks to an improved circuit design, the system voltage is precisely stabilized within the ideal range of approximately 13.8V–14.5V across the entire RPM range and even under heavy load fluctuations. Effectively prevents voltage fluctuations caused by strong vibrations and extreme temperatures off-road, thus protecting the battery and sensitive electronics. 【Optimal Heat Dissipation and Maximum Performance】 【Durability】

Optimal Heat Dissipation: Robust die-cast aluminum housing with large, densely packed cooling fins. Thanks to high-speed forced air cooling and heat conduction to the frame, heat generated under sustained high loads is quickly dissipated. This ensures stable operation at low speeds and under high loads, such as off-road or in long-distance races.

Excellent Environmental Resistance: Advanced sealing properties against water, dust, mud, vibration, and corrosion, specifically designed for the toughest off-road conditions.

Quick and Easy Installation: The connector interface is 100% compatible with the vehicle's original wiring harness for easy and reliable installation.

【Solves Charging Problems During Off-Road Riding】 Replacing this part resolves typical charging problems experienced by motorcycles during off-road use: severely discharged batteries after long journeys or intensive off-road tours, starting problems; rapid battery wear due to constant overcharging or undercharging; occasional engine stalling or electronic control system resets due to brief voltage fluctuations on rough roads. 【Easy Installation】 Typically mounted in the side ventilation area of the frame. Before installation, disconnect the battery's negative terminal and the rectifier connector, remove the mounting screws, replace the component with the new one, and then tighten and reconnect the screws. Compatibility: Compatible models and years: Honda CRF250X (2004–2017), Honda CRF450/CRF450X (2005–2018). Manufacturer Part Number: SH728AA
