The EBMX X-9000 Motor Controller Heat Sink is a passive thermal-management upgrade for the EBMX X-9000 controller on Talaria Sting 4000 (TL4000) and Sting Onroad (TL45). Anodised aluminium adds ~30% convective surface area — the difference between 90-second and 4-5 minute Hyper-mode pulls.

The EBMX X-9000 heat sink (Talaria controller cooling) is a dedicated thermal-management accessory for the EBMX X-9000 controller installed on Talaria Sting 4000 (TL4000) and Sting Onroad (TL45). Dissipates excess heat during sustained Hyper-mode use, preventing thermal cutbacks during long hill climbs and high-load track sessions.
How the EBMX X-9000 Heat Sink Works
The X-9000 controller can deliver up to 250-350 phase amps depending on tune — high current generates significant heat in the MOSFETs. This heat sink mounts directly to the controller housing and provides ~30% more surface area for passive convective cooling, which is the difference between sustained 5-minute Hyper-mode pulls and a controller that throttles back after 90 seconds. Fitment runs across the main Talaria Sting platform, with model-specific notes below.
| Model | Fits | Notes |

| Talaria Sting 4000 (TL4000) with EBMX X-9000 | Yes | Direct fit on X-9000 housing |
| Talaria Sting Onroad (TL45) with EBMX X-9000 | Yes | Direct fit on X-9000 housing |
| Talaria with stock controller | No | Designed for EBMX X-9000 only |
| Talaria with EBMX BAC8000 (72V Upgrade Kit) | No | Different controller housing |
The Electronics Inside

| Compatible models | TL4000 + TL45 with EBMX X-9000 |
| Manufacturer | EBMX |
A controller that thermal-throttles mid-climb is the most frustrating limit on an aftermarket-tuned Talaria. The heat sink is cheap insurance. See the rest of our Talaria parts catalogue for matching components.
Install Notes
Difficulty: Easy. Tools: hex key, thermal paste (recommended). Time: 20 minutes. Disconnect the battery first. Apply a thin layer of thermal paste between the heat sink and controller housing for maximum heat transfer. Re-torque all mounting bolts after the first ride.
Frequently Asked
Will this heat sink fit a stock Talaria controller?
No — it is shaped specifically for the EBMX X-9000 housing. Stock Talaria controllers have a different shape and do not accept this heat sink.
Do I need thermal paste?
Recommended but not mandatory. A thin layer (rice-grain dab spread thin) between the heat sink and controller housing improves heat transfer by 10-20%. Use a CPU-grade silicone thermal compound — automotive thermal pads do not work as well.
How much does this extend Hyper-mode duration?
In real-world testing, riders report Hyper-mode pulls extend from ~90 seconds to 4-5 minutes before controller throttling kicks in. Exact numbers depend on ambient temperature and pack voltage.
Trust Signals & Warranty
EBMX covers the heat sink against manufacturing defects. Talaria USA covers a 30-day return window on unmodified parts and ships from our US warehouse in 2-4 business days.
