More power demands more braking performance.
The new Electro & Company RTR 4-Piston Brake Upgrade Kit is built for riders who want stronger, more controlled braking from their ETM RTR. Whether you’re pushing hard on the trail, riding aggressively on pavement, or upgrading the overall performance of your bike, this kit gives you the braking confidence to match.
More Bite. More Control.
A four-piston caliper applies braking force more evenly across the brake pads, providing a stronger and more consistent clamping force than a smaller caliper design.
That means:
- Increased stopping power
- Improved braking control
- More consistent lever feel
- Better heat management during aggressive riding
- Greater confidence at higher speeds
Instead of simply locking the wheel, a quality braking system should give the rider precise control over how much braking force is applied. The RTR 4-Piston Brake Upgrade Kit is designed to provide that stronger, more predictable feel at the lever.
Built for High-Performance RTR Riders
The ETM RTR platform continues to get faster and more capable, especially as riders add larger motors, upgraded controllers, supermoto wheels and other performance modifications.
But adding more power is only part of building a properly balanced bike.
Your braking system needs to keep up.
The RTR 4-Piston Brake Upgrade Kit gives riders a serious braking upgrade designed around the performance demands of the ETM RTR platform. From technical trail sections to hard pavement braking, the additional clamping capability helps provide the control needed to ride with greater confidence.
Performance You Can Feel
This is the kind of upgrade you notice immediately.
The stronger braking response gives the bike a more controlled, high-performance feel while helping the rider manage speed more precisely. The result is a braking system that feels better suited for aggressive riding and upgraded RTR builds.
Pair the kit with fresh brake pads and properly bedded rotors for the best possible braking performance.
Upgrade Your Stopping Power
Power gets the attention—but control is what makes a fast bike truly perform.
If you’ve upgraded the speed, torque or handling of your ETM RTR, it may be time to upgrade the brakes to match.
More bite. More control. More confidence.
The new RTR 4-Piston Brake Upgrade Kit is available now.
