Custom CNC parts work well on the KTM SX-E 2 for body hardware, mounting brackets, and ancillary components. Drivetrain modifications are a different story. The hub-motor architecture integrates the controller inside the motor package and eliminates chains and sprockets entirely, so external gearing changes are off the table. Before you order anything, these specs define what fits and what doesn't:
- Battery: 9.4 Ah lithium-ion, IP65-rated, removable in one movement. Hold-down plates and bracing must clear the swap path and charging port.
- Motor: 1.8 kW hub motor, 50 Nm. No chain attachment points.
- Ride modes: Walking speed / ~12 mph / ~21 mph. Mode selection is controller-managed; no mechanical override exists.
- Charge times: 0–80% in ~35 minutes, full charge in under 60 minutes via a 500 W external charger on 110–230V.
Three safety systems are non-negotiable. The roll-over sensor, wrist-lanyard kill switch, and forward-throttle activation must remain fully functional after any modification. A CNC part that blocks lanyard access or interferes with the sensor housing fails the build, full stop.
The frame itself shapes your options. KTM built the SX-E 2 around a center-tube aluminum extrusion with few factory holes. Drilling main tubes compromises structural integrity. Clamp-on brackets, subframe anchors, and pivot-point mounts are the right approach.
Straightforward CNC targets for this bike:
- Kickstands (clamp-on, geometry matched to the manufacturer's reported wet weight)
- Footpeg carriers and adjustable footpeg platforms
- Hand-lever mounts and adapter plates for the adjustable levers
- Axle blocks for the HPDC aluminum swingarm
- Reinforced battery hold-down plates
- Skid plates (the OEM unit is HPDC aluminum; CNC 6061-T6 is a direct upgrade)
- Clamp-on brackets for lights, cameras, or number-plate mounts
The SX-E 2 is styled like a full-size motocrosser — adjustable levers, disc brakes, WP fork, 10" wheels — which means owners consistently request CNC upgrades that match full-size ergonomics. Parts should mirror OEM geometry so installation stays straightforward.
Pro Tip: When ordering brake adapter plates, confirm the 140mm front and rear disc diameter and caliper offset before sending files. A 0.5mm error in caliper offset kills rotor concentricity and creates brake drag.
Flying Chip Factory machines CNC parts for the KTM SX-E 2 with direct machinist access for fast iteration, and their in-house CNC kickstand line is already fit-tested on this model.

Where can you buy the KTM SX-E 2 in the United States?
The 2025 KTM SX-E 2 carries a US MSRP of $2,249 and is sold through the KTM authorized dealer network. KTM's dealer locator at ktm.com lets you search by zip code. Most authorized dealers also handle warranty service and can order OEM replacement parts. For e-bike battery care between dealer visits, following manufacturer charging guidelines extends pack life across the rated 1,500 charge cycles.
Flying Chip Factory builds CNC parts that actually fit the SX-E 2
Off-the-shelf parts for a bike this specific rarely exist. Flying Chip Factory's prototype-to-short-run workflow closes that gap.
| Option | Best For | Material/Finish | Lead Time | Price Factors | Fitment Difficulty | Customization |
|---|---|---|---|---|---|---|
| Flying Chip Factory custom CNC | Owners needing exact fitment and fast iteration | 6061-T6 aluminum, stainless; anodize, bead blast, raw | 7–21 days prototype | Machining hours, material, finish, run size | Low — fit-tested geometry | Full |
| Off-the-shelf aftermarket | Budget buyers, common sizes | Varies; often raw or powder-coat | 1–5 days shipping | Fixed price, limited SKUs | Medium — may need shimming | None |
Send a STEP or IGES file, reference photos, and your critical tolerance calls (axle bore, boss locations, mounting surface). Flying Chip Factory quotes from there, typically within one business day. Prototype cycles run CAD to first-article CNC to fit check, with 1–2 revisions standard. Finish options include anodize, bead blast, and raw aluminum. Payment is project-based with a deposit at order. For additional e-bike customization ideas beyond machined hardware, partner resources cover the broader accessory picture.
Every part Flying Chip Factory designs for the SX-E 2 preserves roll-over sensor access, lanyard routing, and charging port clearance. No frame tubes get drilled. See the in-house CNC kickstand line and request a quote at flyingchipfactory.com.
Key Takeaways
Custom CNC parts are viable for the KTM SX-E 2 on body, mounting, and ancillary hardware, but the hub-motor architecture rules out drivetrain modifications entirely.
| Point | Details |
|---|---|
| Hub motor limits drivetrain mods | No chain or sprocket attachment points exist; controller is sealed inside the motor package. |
| Safety systems must survive any mod | Roll-over sensor, wrist-lanyard kill switch, and forward-throttle activation must remain fully functional. |
| Frame requires clamp-on solutions | The center-tube aluminum extrusion has few factory holes; drilling main tubes risks structural integrity. |
| Best CNC targets | Kickstands, footpegs, lever mounts, axle blocks, battery hold-downs, skid plates, and clamp-on brackets. |
| Flying Chip Factory | Offers fit-tested CNC kickstands and prototype-to-short-run machining for the SX-E 2 with direct machinist access. |
