Left-Hand Hydraulic Brake Master Cylinder – Precision Braking for 50cc–250cc ATVs, Scooters, and Pit Bikes
Struggling with spongy brakes or poor response on rough terrain? Upgrading to a hydraulic system with an integrated master cylinder transforms your braking experience, offering smooth, progressive pressure without the slack or delay associated with cable systems. Designed for a direct fit on standard 22mm handlebars, this unit requires no adapters or frame modifications.
Note: This product includes the left-hand lever with an integrated hydraulic master cylinder only. Please verify your handlebar diameter (22mm / 7/8″) before purchasing.
Why choose this model? (Key Benefits):
- Broad Compatibility — Engineered for engines ranging from 50cc to 250cc, including ATVs, scooters, pit bikes, motocross, enduro, and go-karts.
- Quick 15-Minute Installation — Fits standard 22mm (7/8″) handlebars perfectly; no professional mechanic required.
- Instant Hydraulic Response — The integrated pump transfers pressure directly to the calliper, eliminating the mechanical play found in cable-operated systems.
- Reuse Your Existing Hose — Features a standard 10mm connection, meaning you can likely retain your current hydraulic line without additional parts.
- Built for Durability — Constructed to withstand heavy-duty use, constant vibrations, mud, and temperature fluctuations without losing performance.
Performance and Design
Unlike cable-actuated brakes, this integrated hydraulic master cylinder removes mechanical slack, ensuring that every bit of pressure applied to the lever is translated instantly to the calliper. This results in shorter, more controlled braking, whether you are on the track or navigating urban traffic. The sleek black finish blends seamlessly with both aftermarket and original handlebars, while the 22mm clamp provides a secure, firm grip without the need for over-tightening.

Frequently Asked Questions
Is this compatible with my 125cc ATV?
Yes. It is compatible with any engine between 50cc and 250cc—including ATVs, motorcycles, scooters, and pit bikes—provided your handlebar has a 22mm diameter.
Can I use my existing hydraulic hose?
In most cases, yes. If your current hose has a 10mm fitting and is free from cracks or signs of wear, it can be reused. We recommend a visual inspection before installation.
Do I need to bleed the system after installation?
Yes, bleeding the hydraulic circuit is mandatory after any maintenance. Air trapped in the system will reduce braking power and lead to inconsistent performance.
Is there a version for the right side?
This product is specifically for the left side. Please check our other listings for the right-hand version if you need to replace both levers.
