Fitment & installation
Choose your exact KuKirin model and version, then the brake or accessory option. H800/H880 calipers are model-specific. Confirm mounting, rotor clearance and sensor connections before fitting.
What is included?
Contents depend on your selection: a front brake, rear brake, front + rear brakes, complete installation kit, or sensor adapter cable only.
Cables and rotor spacers vary by model and package. Do not assume the brake-only options include the complete kit accessories.

Real Installation Reference
See XOD Hydraulic Brakes Installed on a KuKirin G2
This real top-down photo shows the rear wheel of a KuKirin G2 2026 equipped with XOD hydraulic brakes. Use it as a visual reference for the installed brake setup; follow the instructions for your exact scooter version.
Before installation: verify caliper alignment, rotor clearance, original hardware and sensor connection using the model-specific guide.
Important before ordering: The six complete installation kits below list model-specific accessories. These are the current sales descriptions, not confirmation that every year or production batch has been physically tested. Confirm the exact scooter and selected SKU before fitting; ordinary front, rear and front + rear brake options do not automatically include the same accessories.
1. How to Choose the Correct KuKirin Brake Kit
Step 1: Identify your model
Select the exact scooter model and product option. For G2 Pro, confirm whether the actual scooter matches the 2023 or New Version configuration; the precise year and production-batch boundary still needs confirmation. The documented G2 Master installation covers the 2025 scooter shown in its guide; confirm other versions from their actual brake layout.
Step 2: Confirm kit contents
Check the front and rear calipers, sensor adapter cables and rotor spacers included in your selected kit. Do not assume every variant includes the same parts.
Step 3: Read the installation guide
Review model-specific instructions before fitting. Retain original washers and mounting hardware wherever the guide instructs you to reuse them.
H800 and H880 are different caliper configurations. Do not select them solely by left/right position or assume H800 always means front or rear. Follow the model-specific fitment instructions.
2. Six Complete Installation Kits: Listed Parts
The following accessories are listed for these six complete installation kit options. Open the matching kit or select the same variant in the native product selector. Confirm actual contents and any additional mounting hardware for the selected SKU before installation.
KuKirin G2 Ultra
Front: H880 · Rear: H800
- Sensor adapter cables ×2
- 4mm rotor spacer ×1 for the front wheel
KuKirin G4
Front: H880 · Rear: H800
- Sensor adapter cables ×2
- Reuse original factory metal washers as directed by the installation guide
KuKirin G4 Ultra
Front: H880 · Rear: H800
- Sensor adapter cables ×2
- Check and retain original hardware where the guide specifies
KuKirin G2 Pro · 2023 Version
Front: H800 · Rear: H880
- 5mm rotor spacers ×2
- One spacer for each wheel
KuKirin G2 Pro · New Version product option
Front: H880 · Rear: H880
- 5mm rotor spacers ×2
- One spacer for each wheel
Do not confuse the G2 Pro product options: 2023 lists front H800 / rear H880; New Version lists H880 on both wheels. Both complete-kit sales descriptions list two 5mm rotor spacers, one per wheel. Confirm the actual scooter version, rotor, bracket and fasteners; this is not a universal year-by-year fitment specification.
For other KuKirin models, confirm the exact selected brake option and any required accessories through the relevant installation guide. Do not assume a complete installation kit exists or that the six kits above describe the contents of other variants.
3. KuKirin Fitment Overview
This reference summarizes the current product-option descriptions. Where a specific installation has been documented, use that model-specific guide. Product listings and kit contents alone do not establish compatibility for every production year or batch.
| Model | Front | Rear | Important note |
|---|---|---|---|
| KuKirin G2 | H880 | H800 | Listed complete kit: two sensor adapter cables and one 4mm front rotor spacer. |
| KuKirin G2 Ultra | H880 | H800 | Listed complete kit: two sensor adapter cables and one 4mm front rotor spacer. |
| KuKirin G4 | H880 | H800 | Listed complete kit: two sensor adapter cables; retain original washers as directed. |
| KuKirin G4 Ultra | H880 | H800 | Listed complete kit: two sensor adapter cables. |
| G2 Pro · 2023 | H800 | H880 | Listed complete kit: two 5mm rotor spacers, one per wheel. Confirm version and mounting hardware. |
| G2 Pro · New Version | H880 | H880 | Listed complete kit: two 5mm rotor spacers, one per wheel. Confirm version and mounting hardware. |
| KuKirin G2 Master | H880 | H880 | The documented installation covers the shown 2025 version; confirm other versions before ordering. |
| KuKirin G2 Max | H800 | H880 | Recorded guide reference: more than 2mm caliper-to-bracket clearance. Exact version-specific spacer and bracket requirements remain to be confirmed. |
H800/H880 compatibility is model-specific. Confirm mounting position, rotor clearance, connector and model version before installation.
4. Important Installation Warnings
G2 Pro spacers
Both listed G2 Pro complete kits specify two 5mm rotor spacers, one per wheel. Confirm the exact version, rotor dimensions and mounting hardware before fitting. The sales parts list does not verify every year or production batch; ordinary brake-only options must be checked separately.
G2 Max clearance
The existing G2 Max guide records more than 2mm caliper-to-bracket clearance for the configuration it describes. This is a clearance reference, not rotor-spacer thickness. The exact front and rear spacer, bracket and fastener requirements still need confirmation for each version; stop if any component rubs or binds.
G4 original washers
Do not discard original factory metal washers. Reuse the original washers and hardware where the model-specific guide instructs you to do so.
Sensor adapters
Mechanical fitment and electrical connector compatibility are separate checks. The G2, G2 Ultra, G4 and G4 Ultra complete-kit descriptions list two dedicated adapter cables each. The two G2 Pro complete-kit descriptions list spacers, not the same adapter contents. Confirm the selected SKU and actual connector before ordering; do not infer electrical compatibility from pin count alone.
Brackets and fasteners: The G2 Pro and G2 Max records do not establish a universal rule to reverse a supplied bracket or reuse the original bracket. Confirm the exact bracket, its orientation, fasteners and actual box contents for the selected SKU. The six complete-kit lists above do not confirm that brackets or specific bolts are included.
Hydraulic brake installation is safety-critical. If you are unsure about caliper alignment, rotor clearance, hose routing or bleeding, ask a qualified mechanic to inspect the installation before riding.
5. Not Sure Which Kit Fits? Send These Photos
If the scooter version or brake layout is uncertain, send clear photos to XOD support before ordering.
Show the disc side, fork and caliper mounting location.
Show the disc side, swingarm and caliper mounting location.
Show the electrical plug clearly so sensor compatibility can be checked.
Include the exact model name and version if known. Clear photos help support identify the correct configuration before purchase.
6. Product Specifications and Purchase Notes
| Product family | XOD H-Series hydraulic brake upgrade kit |
|---|---|
| Caliper configurations | H800 / H880, selected according to model-specific fitment |
| Brake sensor connector | 2-pin waterproof connector on supported configurations; confirm adapter requirements for your scooter |
| Caliper type | Dual-piston hydraulic caliper |
| Material | Forged aluminum alloy, according to the existing product description |
| Approximate hose length | Existing product reference: front 1350mm / rear 2100mm. Confirm the actual lengths for the selected SKU and full steering, suspension and folding travel before cutting. |
| Rotor compatibility | 140mm / 160mm options are listed in the existing product description. Verify rotor size and mounting clearance for your scooter. |
| Hydraulic fluid | XOD H-Series systems use mineral oil. Do not mix DOT fluid into a mineral-oil system. |
| Lever configuration | Existing product reference: left lever = rear brake, right lever = front brake. Confirm your selected configuration before fitting. |
Brakes are described as pre-bled in the existing product content. If a hose is shortened or the hydraulic circuit is opened, follow the applicable connection and bleeding instructions, inspect for leaks and check lever pressure. Repair any leak before bleeding and testing; do not ride with a soft, inconsistent lever or hydraulic pressure loss.
7. Frequently Asked Questions
Which XOD brake configuration fits KuKirin G4?
The current G4 complete-kit description lists front H880 and rear H800 with two sensor adapter cables. Retain original factory metal washers where the model-specific installation guide directs. Confirm the actual scooter version, connector and selected package; brake-only options do not automatically include the complete-kit accessories.
Which kit fits KuKirin G2 Ultra?
The current G2 Ultra complete-kit listing specifies front H880 and rear H800, two sensor adapter cables and one 4mm front rotor spacer. Confirm the actual scooter version and selected package before fitting; brake-only options do not automatically include these accessories.
What is the difference between G2 Pro 2023 and the latest version?
The current 2023 product option lists front H800 and rear H880; the New Version option lists H880 on both wheels. Both complete-kit descriptions list two 5mm rotor spacers, one per wheel. The exact year and production-batch boundary still needs confirmation, so check the actual brake layout, rotor and mounting hardware before fitting.
Does KuKirin G2 Master have a year restriction?
The listed product configuration uses H880 on both wheels, but the documented installation covers the G2 Master 2025 scooter shown in its guide. Compatibility across every year or production batch is not confirmed by that example. Check other versions using the actual disc sides, caliper mounts, rotor clearance and connector before ordering.
Do all KuKirin kits include the same accessories?
No. The G2, G2 Ultra, G4 and G4 Ultra complete-kit descriptions list two sensor adapter cables each; the two G2 Pro complete-kit descriptions list two 5mm rotor spacers, one per wheel. Other listed accessories also vary by model. Front, rear and front + rear brake-only options do not automatically include complete-kit accessories. Confirm the selected SKU and actual mounting hardware before installation.
What photos should I send if I am unsure?
Send front and rear wheel photos showing the rotor side and caliper mounting location, plus a close-up of the brake-lever sensor connector. Include the exact scooter model and version.
Can I install the hydraulic brakes myself?
Installation requires correct caliper alignment, rotor clearance, hose routing and sensor checks. If you are not experienced with hydraulic brake work, ask a qualified mechanic to install and inspect the system.
