Rmstator RMS957-108590 Voltage Regulator Bypass Harness for BMW Motorcycles

The Rmstator RMS957-108590 is an improved heavy-duty voltage regulator bypass harness designed to eliminate common electrical charging system problems on BMW motorcycles. This plug-and-play wiring harness connects the voltage regulator directly to the battery, bypassing the main wiring harness to prevent the corrosion and electrical resistance issues that plague stock configurations.

Key Features:

• Heavy-duty bypass harness construction for improved reliability
• Direct battery connection eliminates main harness failure points
• Automotive-grade wiring with OEM-quality heavy-duty connectors
• Cross-link braided copper wire with very low electrical resistance
• Resists heat, oil, acid, gasoline, and other corrosive elements
• Plug-and-play design for straightforward installation
• Manufactured with controlled quality processes matching OEM standards

This bypass harness addresses a common failure mode where corrosion in the stock wiring harness increases electrical resistance, leading to overheating, melted connectors, and premature voltage regulator and stator failure. By routing power directly to the battery, the RMS957-108590 significantly improves charging system reliability and longevity. Replaces BMW OEM# 61 31 2 346 550.
