The R1 and R1+ Left the Factory With Different Rotors. This Kit Fits Both.
ReRode gave the R1 a 203mm front rotor and the R1+ a 220mm one, and made the R1+ heavier and faster on top of that. Both are fixed discs. The V2 kit puts either bike on the same 240 or 250mm floating rotor, with a genuine Sur-Ron Ultra Bee caliper and master cylinder and a steel-braided line.
- Up to 30% more stopping power — on the R1 and on the R1+
- One bracket for both bikes — no separate part to get wrong at checkout
- Genuine Ultra Bee caliper + master cylinder — not a copy
- Holds up on repeat stops — floating rotor, cooling grooves, semi-metallic pads
Stock ReRode R1 / R1+ Front Brake vs EBG Front Brake Kit V2
| Stock ReRode R1 / R1+ | EBG Front Brake Kit V2 | |
|---|---|---|
| Stopping power | Baseline | Up to 30% more |
| Rotor | 203 mm (R1) or 220 × 2.3 mm (R1+) | 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: 9–23% from rotor diameter depending on which ReRode you have, the rest from pad compound, line stiffness and the caliper.
Upgrading an R1 to R1+ Brakes, and Then Past Them
The obvious move on an R1 is to fit the R1+ rotor and stop there. That gets you 17mm and nothing else — still a fixed disc, still the factory line, still the factory pads. This kit changes the rotor, the caliper, the master cylinder, the pads and the line together, which is why the gain does not stop at diameter.
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 ReRode R1 / R1+ kit we ship uses genuine Sur-Ron Ultra Bee parts.
Which ReRode R1 / R1+ Brake Option Do I Need?
Four ways to buy it:
- Brake Kit + Front Rotor Guard + Rotor — the whole thing, plus a guard over the rotor. Most riders pick this.
- Brake Kit + Rotor — the whole thing without the guard.
- Brake Kit Only — you are keeping a rotor you already own.
- Front Brake Bracket Only — just the radial mount bracket, M5 x 45mm.
Options that include a rotor let you choose the V2.1 or V3.0 rotor design. Both are 240 or 250mm at 3.5mm.
