Built for 8S LiPo configurations and capable of reaching up to 90,000 RPM, this motor is the ultimate solution for RC enthusiasts pushing the limits of performance. Castle Creations has reinforced the internal structure with a stainless-steel sleeve and paired it with a massive 8mm shaft to withstand the brutal forces of high-speed acceleration. The Castle M-CC060-0091-00 4-pole motor with 8mm shaft and 8AWG silicone wire is designed to deliver maximum torque and top-end speed while maintaining thermal stability and mechanical integrity.
Key features of the Castle M-CC060-0091-00 1721-2400kV motor
- Stainless-steel rotor sleeve – reinforces structural integrity under extreme RPM loads
- 8mm hardened shaft – supports aggressive gearing and high-speed torque transfer
- Low-resistance 8AWG silicone wire – ensures efficient current flow with minimal heat buildup
- Oversized bearings – reduce vibration and extend operational lifespan
- Sensor-based startup – eliminates cogging and improves throttle precision
- Rebuildable design – allows rotor, shaft, and bearing replacement for long-term reliability
How does the stainless-steel sleeve enhance rotor durability?
The Castle M-CC060-0091-00 with stainless-steel sleeve and reinforced rotor is built to withstand the intense centrifugal forces generated during high-RPM operation. The sleeve adds rigidity to the rotor, preventing deformation and maintaining balance even under extreme acceleration. This structural reinforcement is essential for speed run and drag applications where motor integrity directly affects performance and safety. Combined with Castle’s precision engineering, the sleeve ensures that the motor remains stable and reliable at speeds exceeding 90,000 RPM.
Why is the 8mm shaft critical for high-torque applications?
The Castle M-CC060-0091-00 4-pole motor with 8mm shaft and 8AWG silicone wire features a hardened 8mm stainless-steel shaft designed to handle aggressive gearing and torque transfer. This oversized shaft minimizes flex and mechanical stress, allowing the motor to maintain consistent power delivery during full-throttle launches and sustained high-speed runs. Whether installed in a 1/8 scale drag build or a 1/7 scale speed run platform, the shaft ensures that torque is transferred efficiently and reliably to the drivetrain.
How does the stator design improve efficiency and runtime?
The Castle 1721 motor with 8mm bullet connectors and low-resistance stator utilizes proprietary winding techniques to reduce electrical resistance across the stator assembly. This low-resistance configuration minimizes heat generation, allowing the motor to operate cooler and more efficiently. The result is longer runtime on a single charge and improved power delivery under sustained loads. Paired with high-strand 8AWG silicone wire, the motor maintains optimal current flow, making it ideal for extended speed runs and repeated drag passes.
What role do the bearings and vibration dampening play?
The Castle 2400kV motor with vibration dampening and oversized NMB bearings is equipped to handle the mechanical stress of high-speed operation. Oversized NMB bearings reduce friction and absorb vibration, protecting internal components from wear and fatigue. The integrated vibration dampening system further enhances stability, ensuring smooth rotation and consistent performance. These features contribute to the motor’s long-term reliability, especially in demanding environments where precision and durability are non-negotiable.
Is this motor compatible with Castle’s XLX2 ESC?
Yes. The affordable Castle 1721-2400kV motor with SmartSense startup and XLX2 ESC compatibility is designed to pair seamlessly with Castle’s Mamba XLX2 ESC. This combination unlocks advanced tuning capabilities and ensures optimal performance across all driving conditions. SmartSense startup logic provides smooth, sensor-based launches, while the ESC manages timing and power delivery dynamically. Together, they form a high-performance powertrain capable of handling the most extreme RC builds.
Why is this motor the best Castle upgrade for speed-focused builds?
The Castle M-CC060-0091-00 1721-2400kV sensored brushless motor for 1/8 and 1/7 scale vehicles is purpose-built for speed enthusiasts who demand uncompromising power and precision.

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.
- Depending on what you choose at checkout, your order will usually be delivered either the next working day or within 2 working days. For next day delivery please place your order before 2:00pm. Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
- If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
- We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
- As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
- If a product is marked as "Dispatched within 3 working days" delivery usually takes around 3 to 5 working days from when your order is placed.
- For customers in Inverness and other parts of the Scottish Highlands deliveries can take up to 2 working days even if you select next day delivery as couriers do not currently offer a guaranteed next day service to those areas.
