The Fastest Bike in Its Class Still Brakes on a 220mm Rotor
The Ventus One is a 72kg machine quoted at 130–140km/h, and it stops on a 220mm fixed front rotor. Stopping energy climbs with the square of speed, so the Ventus asks more of its front brake than almost anything else in this class. The V2 kit fits a 240 or 250mm floating rotor, a genuine Sur-Ron Ultra Bee caliper and master cylinder, and a steel-braided line.
- Up to 30% more stopping power — on the bike in this class that needs it most
- Built for repeat stops from speed — floating rotor with cooling grooves, semi-metallic pads
- Genuine Ultra Bee caliper + master cylinder — not a copy
- Lever feel that does not go soft — steel-braided line with a PTFE core
Stock Ventus One Front Brake vs EBG Front Brake Kit V2
| Stock Ventus One | EBG Front Brake Kit V2 | |
|---|---|---|
| Stopping power | Baseline | Up to 30% more |
| Rotor | 220 mm | 240 or 250 × 3.5 mm |
| Rotor type | Fixed, one-piece solid | Floating, bobbinless, with cooling grooves |
| Caliper | Factory OEM | Genuine Sur-Ron Ultra Bee |
| Master cylinder | Factory OEM | Genuine Sur-Ron Ultra Bee, right hand |
| Pads | Factory pads | Semi-metallic, genuine Surron |
| Line | Standard rubber hose | Steel-braided, PTFE core, DOT4 |
Where the 30% comes from: 9–14% from rotor diameter alone, the rest from pad compound, line stiffness and the caliper.
Speed Is Why This One Matters
Double the speed and the brake has four times the energy to get rid of. A 72kg bike arriving at a corner at 130km/h is asking its front rotor to shed roughly four times what the same bike sheds 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 V2 rotor is thicker, floating, and grooved rather than simply wider.
Genuine Sur-Ron Ultra Bee Parts — Not Copies
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 Brake Option Do I Need?
Four ways to buy it:
- Brake Kit + Front Rotor Guard + Rotor — everything you need in one box, guard included.
- Brake Kit + Rotor — everything except the guard.
- Brake Kit Only — caliper, master cylinder, line, pads and bracket; bring your own rotor.
- Front Brake Bracket Only — bracket alone, M5 x 45mm, for riders sourcing the rest themselves.
Options that include a rotor let you choose the V2.1 or V3.0 rotor design. Both are 240 or 250mm at 3.5mm.
