Yadea KS3 & KS5 Left Brake Lever Assembly - OEM

Genuine Yadea KS3 / KS5 Left Brake Lever & Perch Assembly. This OEM replacement part is designed specifically for the Yadea KS series, providing the exact leverage ratio and cable pull required for consistent braking performance.

As a genuine factory component, it features a built-in motor cutoff sensor (e-brake) that immediately disengages the motor when the lever is pulled—a critical safety feature for electric scooters. The durable black powder-coated finish ensures resistance to corrosion and wear from daily use.
