A Shield Guard on the Fastest Bike in the Class
The Ventus One is a 72kg machine quoted at 130–140km/h, stopping on a 220mm fixed front rotor. This kit fits a 240 or 250mm floating rotor, a genuine Sur-Ron Ultra Bee caliper and master cylinder and a steel-braided line, behind the closed-face shield guard.
- Closed-face guard — a solid plate over the disc, in five anodised finishes
- Built for repeat stops from speed — floating rotor with cooling grooves, semi-metallic pads
- Up to 30% more stopping power — on the bike in this class that asks the most of its front brake
- Genuine Ultra Bee caliper + master cylinder — not a copy
Classic Shield or Open Frame — Which EBG Guard?
This kit and the V2 kit are the same brake. The only thing that changes is the rotor guard, and that is a choice about how you ride, not about stopping power.
| Classic Shield — this kit | Open Frame — V2 kit | |
|---|---|---|
| Guard face | Solid plate, closed face | Open frame, rotor left exposed |
| Colours | 7 — including Grey and Dark Brown | 5 |
| Caliper | Genuine Sur-Ron Ultra Bee | Identical |
| Master cylinder | Genuine Sur-Ron Ultra Bee, right hand | Identical |
| Rotor | 240 or 250 × 3.5 mm floating | Identical |
| Pads and line | Semi-metallic, steel-braided PTFE | Identical |
| Price | The same either way — pick the guard you prefer | |

Speed Is Why This One Matters
Double the speed and the brake has four times the energy to shed. A 72kg bike arriving at a corner at 130km/h asks roughly four times what the same bike asks at 65km/h — and it has to do it again at the next corner. That is a heat problem before it is a grip problem, which is why the rotor here is thicker, floating and grooved rather than simply wider.
Genuine Sur-Ron Ultra Bee Hydraulics
The market is full of Ultra Bee caliper and master cylinder copies. They photograph the same and cost less, and the difference is in the piston bores and the seals — which you find out on a steep descent. Every Ventus One kit we ship uses genuine Sur-Ron Ultra Bee parts.
Which Ventus One Option Do I Need?
- Brake Kit + Front Rotor Guard + Rotor — the complete kit with the classic shield guard. Choose the V2.1 or V3.0 rotor.
- Brake Kit + Rotor — the same, without the guard.
- Brake Kit Only — for a bike already running a 240 or 250mm rotor.
- Front Brake Bracket Only — the radial mount bracket on its own, M5 x 45mm.
