Compatibility Between Sur-Ron Brake Pump & Talaria Sting
| Feature | Sur-Ron Brake Pump | Talaria Sting MX3/MX4 Compatibility |
|---|---|---|
| Handlebar Clamp Size | 22.2mm (Standard) | ✅ Direct fit – No modification needed |
| Brake Fluid Type | DOT 4 or DOT 5.1 | ⚠️ Talaria uses mineral oil – Requires brake fluid change |
| Brake Hose Length | ~900-1000mm | ✅ Similar length – May need adjustment |
| Banjo Bolt & Fitting | Standard hydraulic | ⚠️ Fitting angle may differ – Some adjustments needed |
| Master Cylinder Thread | M10x1.0mm | ✅ Compatible with Talaria hoses (with minor adjustments) |
| Calliper Compatibility | Sur-Ron OEM & aftermarket callipers | ✅ Works with Talaria’s callipers if fluid type is changed |
Key Notes for Installing Sur-Ron Brake Pump on Talaria Sting MX3/MX4:
✔ Handlebar Clamp Fits Perfectly – Both bikes use a 22.2mm standard handlebar, 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.
