Front Ultra Bee Brake for Surron, Talaria, E-Ride Pro, Super73, Ridstar, Macfox, and More

CHOOSE YOUR ROTOR SIZE!!!
Available with a 203mm, 220mm, or 240mm front rotor. Select the rotor that is roughly 40mm larger than your bike’s stock front rotor for the best balance of power and fitment. If you’re unsure of your stock size, reach out and we’ll help you choose.Front Ultra Bee Brake Kit – Moto-Grade Front Brake Upgrade

Add serious front-end stopping power with the Kaos Customs Front Ultra Bee Brake Kit. Most riders upgrade the rear first — but your front brake does the majority of your stopping, and a moto-grade front setup transforms how your bike slows and handles. This complete hydraulic kit replaces weak, fading stock front brakes with real power, control, and modulation.

Choose Your Caliper: OEM or Replica — Clearly Labeled
We sell both, and we tell you exactly which is which:

• Full OEM Ultra Bee Brake System – The genuine Ultra Bee caliper and brake system. Strongest braking power, more back pressure for sharper lever feel and modulation, and the highest overall build quality.
• Replica Ultra Bee Brake System – A lower-cost replica caliper that still delivers strong, reliable braking power. Slightly less powerful with a bit less back pressure, so lever feel is marginally softer, and build quality is a step below the genuine unit. A great-value major upgrade over stock.

Both bolt up with the included bracket and hardware, and both dramatically outperform your stock front brakes.

What’s Included

• Complete Front Brake Assembly – Ultra Bee caliper, brake line, and lever, pre-bled and ready to install. Choose OEM or replica.
• Upgraded Front Rotor – Your choice of 203mm, 220mm, or 240mm.
• Caliper Bracket & Mounting Hardware – Precision-machined 6061-T6 aluminum bracket and all hardware needed for a clean, bolt-on install.
