Compatibility Between Sur-Ron Brake Pump & Talaria Sting

🎵 Key Notes for Installing Sur-Ron Brake Pump on Talaria Sting MX3/MX4:

✔ Handlebar Clamp Fits Perfectly – Both bikes use a 22.2mm standard handle-bar, so no modification is needed.
✔ Brake Line Length is Similar – In most cases, the brake hose is plug-and-play or requires minor routing adjustments.
⚠ Brake Fluid Needs to Be Changed – Talaria uses mineral oil, while Sur-Ron’s brake pump is designed for DOT 4/5.1. Mixing fluids can damage seals, so a full system flush is required.
⚠ Banjo Fitting May Need Adjustment – The angle of the hydraulic fitting may differ slightly, requiring rerouting or minor adjustments.
✔ Works with Talaria’s Stock Caliper – If the fluid is properly swapped, this pump can operate Talaria’s braking system without major issues.
