LOCOPOW 7/8" Left-Hand Hydraulic Brake Lever Master Cylinder is a drop-in replacement hydraulic brake lever assembly designed for 7/8" (22mm) handlebars on many pit bikes, scooters, ATVs and small-displacement motorcycles. This compact master cylinder and lever assembly offers an affordable, easy-to-install option when the original left-side hydraulic brake control is damaged or worn. It’s a non-OEM replacement part built to fit standard 7/8” handlebars and common Chinese-made minibikes, mopeds, and GY6-powered scooters. Before ordering, compare the photos and mounting dimensions to your existing part to ensure compatibility.

Will this master cylinder fit my 7/8" handlebar bike or scooter?

The LOCOPOW unit is engineered for 7/8" (22mm) handlebars and is compatible with many small-displacement machines. It suits a wide range of Chinese-brand minibikes, ATVs, and GY6 scooters, but it is not universally interchangeable with every model.

• Mounts on 7/8" (22mm) tubular handlebars only.
• Commonly fits 50cc–250cc 4-stroke engines and GY6 scooters.
• Typical compatible brands: TaoTao, Buyang, Znen, Roketa, Kazuma and similar.
• Replacement for China-made Honda-style pit bikes (CRF50/70/80, XR50/70 copies).

How easy is installation and what tools are required?

Installation is straightforward for anyone comfortable with basic motorcycle or ATV maintenance. The assembly replaces the existing left-side master cylinder, clamps to the handlebar, and connects to the hydraulic brake hose; minor adjustments and fluid bleeding are usually required.

• Requires standard hand tools: hex keys, screwdrivers, and a wrench set.
• Brake line connection uses common fittings—verify threads before tightening.
• After mounting, bleed the brake system to remove air for consistent lever feel.
• Follow safety checks: torque clamp bolts and inspect for leaks before riding.

What materials and features does this lever assembly offer?

This master cylinder is designed for rugged everyday use while keeping costs low. It is offered as a high-quality aftermarket replacement rather than an original equipment part, so finish and tolerances may vary slightly from OEM components.

• Durable metal lever and cast master cylinder body for everyday durability.
• Pre-drilled clamp for secure 7/8" handlebar mounting.
• Standard reservoir and bleed screw for maintenance access.
• Sold as a replacement part—inspect fitment pictures and specs before purchase.

Who is this for? This LOCOPOW left-hand hydraulic brake lever master cylinder is aimed at riders and mechanics who need a reliable, cost-effective replacement for damaged or leaky left-side brake controls on 7/8" handlebars. It’s ideal for owners of pit bikes, dirt bikes, scooters, mopeds, and ATVs that use common Chinese-brand components or Honda-style copies manufactured in China. If you want a direct-fit aftermarket option that restores hydraulic braking function without the price of OEM parts—provided you confirm compatibility—this part is a practical choice. For best results, compare the product images and measure your current master cylinder before ordering.
