Brake caliper DEXTER Atomika radial 6-piston brake caliper in black
Radial bolted 6-piston performance brake caliper for racing, high-performance scooter setups and high thermal loads.
The DEXTER Atomika is a radial 6-piston brake caliper for performance-oriented brake systems. The six brake pistons distribute the hydraulic pressure evenly across the brake pad and ensure a very direct, clearly controllable braking effect. The Atomika was developed for racing applications and intensive use, where constant braking performance, thermal stability and clean resetting of the pistons are crucial.

What makes the DEXTER Atomika so special
6-piston design: even pressure distribution on the brake pad
Radial mounting: designed for matching performance caliper brackets
Large pad surface: compatible with brake pads in Ducati 916 design
high thermal reserves: housing design for better heat dissipation
for intensive use: developed and tested in endurance use
6 pistons for pressure, control and even braking force
The 6-piston design of the DEXTER Atomika ensures that the braking force is transferred evenly to the brake pad over a large area. This not only improves pure deceleration, but also the controllability of the brake lever. Especially with fast scooters, sporty conversions or longer downhill sections, a cleanly controllable brake is more important than an aggressive on/off pressure point.
Brake pads in Ducati 916 design
Atomika uses brake pads from the motorcycle sector in the Ducati 916 design, providing a large selection of different friction compounds - from sporty road compounds to more resilient racing pads.
more pad surface: over 70 % larger friction surface compared to many conventional scooter pads
large selection: various compounds available for road, sport and race track use
Brake pads not included: suitable pads must be ordered separately
Cooling and piston guide for permanent load
The outer housing design is designed to dissipate heat. Under heavy load, the brake calliper can dissipate heat better to the ambient air, which keeps braking performance more stable. Internally, the Atomika is also designed to function reliably at high temperatures: The piston guide is designed to prevent the pistons from jamming and support even resetting.
Important installation note
only with suitable bracket: the brake calliper can only be used with the DEXTER brake calliper bracket provided for this purpose
Suitable forks: bracket available for Zip, Quartz, Skipper and ET4 applications
Brake pads separately: pads are not included in the scope of delivery
Check brake system: Brake master cylinder, brake disk, line, clearance and wheel/rim distance must match the setup
For racing and intensive use
The Atomika was designed for high loads and repeated hard braking maneuvers. In endurance use, it's not just peak values that count, but above all consistent function over a long period of time. This is precisely where the large pad surface, good heat dissipation and reliable piston return play to their strengths.
Safety note
Work on the brake system is safety-relevant. Installation, bleeding and testing should only be carried out by qualified personnel. After installation, the pressure point, tightness, freedom of movement, brake pad seating and screw connections must be carefully checked.

Conclusion
The DEXTER Atomika 6-piston brake caliper is a clearly performance-oriented brake caliper for setups where braking power, modulation and thermal stability are more important than a standard solution. With a large pad surface, Ducati 916 pad shape and radial mounting, it is a strong basis for sporty scooter brake systems - provided that the bracket, brake disk and hydraulics are suitably matched.
FAQ about the DEXTER Atomika 6-piston brake caliper
No. The matching brake pads are available separately. The Ducati 916 design is used.
No. Installation is only possible with the appropriate DEXTER brake calliper bracket. In addition, the brake disk, rim and hydraulics must match the setup.
This design offers a large friction surface and a wide selection of pad compounds from the motorcycle sector. This allows the brake to be better matched to the intended use and riding style.
This depends on the vehicle, country, owner, complete braking system and registration situation. The legal requirements and possible registration should be clarified before use on public roads.
