Description

🔧 What a Master Cylinder Is

In general automotive and motorcycle systems, a master cylinder is the hydraulic component that converts mechanical force (from the brake or clutch lever/pedal) into hydraulic pressure to operate brakes or clutch systems through fluid pressure in lines to calipers or slave cylinders. Wikipedia

🏍️ About KTC Master Cylinders

KTC (sometimes branded as KTC Racing or Kytaco) sells aftermarket motorcycle brake/clutch master cylinders — typically for sport, scooter, or universal fit applications.

Typical Features of KTC Master Cylinders

• Designed for motorcycle braking systems (front brake or clutch hydraulics).

• May include integrated fluid reservoir and piston assembly in one unit.

• Manufactured from aluminum alloy for strength and lightweight performance.

• Radial or axial designs — radial types typically offer more direct pressure generation, while axial designs are simpler and traditional layouts.

• Adjustable pivot / lever position for customizing feel and response.

• Compatible with standard brake fluid types (DOT 3, DOT 4).

Note: “KTC” in some contexts just indicates Kytaco/KTC Racing aftermarket parts, not a specific OEM brand name tied to motorcycle manufacturers.

🛠️ Common Specs You’ll See On KTC Master Cylinders

These vary by model, but typical specs include:

⚙️ Piston Diameter

• Often around 12.7 mm to 19 mm depending on model — smaller diameter = more travel, larger = more pressure. KTC Racing+1

⚙️ Material

• Aluminum alloy body for corrosion resistance and strength.

⚙️ Design Type

• Axial or radial mount styles:

  • Axial: piston pushes fluid forward along axis.

  • Radial: piston pushes fluid roughly perpendicular to handlebar, often used on high-performance bikes.

⚙️ Features

• Integrated brake fluid reservoir.

• Adjustable lever pivot for tuning throw and feel.

⚙️ Fitment

• Many KTC master cylinders are universal fit, but some are designed for specific models (e.g., scooters or sport bikes).

🧠 How It Works (General Master Cylinder Function)

• Lever action compresses a piston inside the master cylinder bore.

• This creates hydraulic pressure in the brake fluid.

• Pressure travels through lines to the caliper (brake) or slave cylinder (clutch) to perform the action.

• A reservoir supplies fluid and keeps air out of the system.

📌 Summary

📍 Notes

• Exact dimensions and part numbers vary depending on the specific model and motorcycle you intend to fit.
