XOD H800/H880 Hydraulic Brake Upgrade Kit for KuKirin Electric Scooters
Upgrade compatible KuKirin electric scooters with the XOD H-Series hydraulic brake system. It is built for riders who want smoother hydraulic braking control, stronger brake response and more predictable stopping performance than many stock mechanical disc brake setups.
Choose by model + wheel position + brake layout. H800 and H880 are different caliper versions, and correct fitment depends on brake disc side, caliper position, front fork or rear swingarm structure and model year.
Choose the Correct Kit in 3 Steps
Start with G4, G2 Max, G2 Master 2025 or your exact scooter option.
Select front brake, rear brake or front + rear set according to your upgrade need.
Check brake disc side, caliper position, fork structure and connector before ordering.
Quick Fitment Reminder
For the rear wheel, the brake disc side is usually easier to judge. For the front wheel, do not choose H800 or H880 only by looking at the left or right side. You must also check the front fork type and caliper mounting position.
Not sure which version fits your scooter? Read the XOD H800/H880 Fitment Guide before ordering.
