Magura MT5 eSTOP Hydraulic Brake – 4-Piston Set for Sur-Ron, Talaria & E-Bikes

The Magura MT5 eSTOP is a hydraulic disc brake built for high-mass electric platforms. It fits Sur-Ron and Talaria electric motorcycles, electric scooters, E-MTBs, S-Pedelecs and classic mountain bikes. The set pairs a 4-piston caliper with a Carbotecture® body, a 2-finger aluminium lever and a 2200 mm hose. Total weight is roughly 255 g without a rotor.

This model is the electric-specific version of the award-winning MT5 platform. A radial master cylinder sits inside the lever body, which cuts friction and transmission losses. As a result, the brake responds from the very first millimetre of lever travel. Meanwhile, the four pistons press the pads evenly against the disc for consistent bite.

The set arrives with 8.S (Sport) pads. This compound balances raw power, modulation and service life under the loads that heavier e-platforms generate. The system runs on Magura Royal Blood mineral oil, and recommended rotor sizes are 180, 203 and 220 mm. One set covers one wheel.

Key Benefits

• 4-piston caliper – pads clamp the disc evenly, so stopping distances shorten and control becomes more precise.
• Radial master cylinder – a more sensitive braking start plus smoother modulation on long descents.
• 8.S (Sport) pads – stable performance and long life under the higher loads of electric platforms.
• Carbotecture® body – a composite construction that keeps the set at roughly 255 g without a rotor.
• 2-finger aluminium lever – a solid metal lever suited to sustained braking on steep descents.
• 2200 mm hose with rotating connector – long enough for bicycles and for larger e-moto frames such as Sur-Ron or Talaria.
• Magura Royal Blood mineral oil – a non-hygroscopic system that needs no DOT fluid.
• 180 / 203 / 220 mm rotor support – a larger disc improves heat management on fast, heavy machines.

Who Is This Brake Set For?

This Magura MT5 eSTOP set suits Sur-Ron and Talaria electric motorcycles, electric scooters, E-MTB electric mountain bikes and S-Pedelec fast e-bikes. It also works on classic mountain bikes without a motor. Riding disciplines cover trail, enduro and downhill, as well as everyday urban riding.

Many riders choose the set as a brake upgrade on e-moto platforms. For Sur-Ron and Talaria builds, you will need suitable mounting adapters together with a 203 or 220 mm rotor. Check your frame or fork specification before selecting the disc size.

Beyond that, the set fits riders who need braking power at higher mass and higher speed. It equally suits anyone chasing precise modulation on technical trails. Remember that one set covers a single wheel, so order two for a full front-and-rear conversion.

What’s in the Box

• 1× brake lever assembly with master cylinder and 2-finger lever
• 1× 4-piston caliper fitted with 8.S (Sport) pads
• 1× 2200 mm brake hose with rotating connector
• 2× hose fittings – olive (ring) and insert (barb)

Brake rotors and mounting adapters are sold separately. Choose the rotor according to your frame or fork specification, either 203 or 220 mm.

Technical Specifications

Why Choose the Magura MT5 eSTOP?

Magura is a German manufacturer based in Bad Urach, active since 1893. The MT series is the brand’s bicycle and electric-platform brake family, and the eSTOP variant was tuned specifically for motorised machines. That tuning shows in the pad compound and the caliper’s four-piston layout.

The combination of a radial master cylinder and a Carbotecture® caliper is unusual at this weight. You get 4-piston clamping force in a package of roughly 255 g, minus the rotor. Consequently, riders gain stopping power without adding significant mass to the machine.

Mineral oil is another practical advantage. Royal Blood does not absorb water from the air, so the fluid stays stable between services. In addition, the 2200 mm hose removes the usual routing headache on longer Sur-Ron and Talaria frames.

Frequently Asked Questions

Does this brake fit a Sur-Ron Light Bee?

• Yes, the set is designed for Sur-Ron platforms.
• You will need suitable mounting adapters.
• Fit a 203 or 220 mm rotor for best heat control.

Will it work on a Talaria Sting?

• Yes, Talaria electric motorcycles are a listed application.
• The 2200 mm hose covers the frame routing.
• Adapters and the rotor are purchased separately.

Is one set enough for the whole bike?

• No, one set covers one wheel only.
• Order two sets for front and rear.
• Each set includes its own lever, caliper and hose.

Which brake fluid does it use?

• Magura Royal Blood mineral oil.
• DOT fluid is not used in this system.
• Mineral oil does not absorb moisture from the air.

What rotor size should I choose?

• Recommended sizes are 180, 203 and 220 mm.
• Heavier electric machines benefit from 203 or 220 mm.
• Always follow your frame or fork specification.

How much does the set weigh?

• Roughly 255 g without the rotor.
• The Carbotecture® caliper body keeps mass low.
• The lever blade is aluminium, in a 2-finger shape.

Can I use it on a normal mountain bike?

• Yes, it fits classic mountain bikes without a motor.
• Trail, enduro and downhill riding are all covered.
• E-MTB and S-Pedelec builds work equally well.

What are 8.S (Sport) pads?

• The pad compound supplied inside the caliper.
• It balances power, modulation and service life.
• The compound targets heavier electric platforms.

The Magura MT5 eSTOP brings 4-piston stopping power, a radial master cylinder and a 2200 mm hose to Sur-Ron, Talaria, E-MTB and S-Pedelec builds. Add your preferred rotor and adapters, then bleed the system with Royal Blood mineral oil. One set equips one wheel.
