1721 Sensored Brushless Motor, 1260kV (CSE060010000)
1721 Sensored Brushless Motor, 1260kV (CSE060010000)
The 1721-1260Kv sensored brushless motor is a high-performance RC motor designed for serious large-scale bashers, delivering strong speed, torque, and rapid acceleration. Built with precision-machined components, high-strength magnets, and advanced winding techniques, it’s engineered for reliable, consistent performance in demanding conditions.
Its 4-pole, 12-slot design delivers excellent efficiency and helps run cooler, while sensor-based timing eliminates the need for mechanical timing adjustments and provides uniform timing and torque in both directions. Oversized NMB bearings and a vibration-damping system extend bearing life, while high-temperature neodymium magnets with a Kevlar wrap preserve rotor integrity under tough running conditions. Proprietary winding techniques minimize resistance for cooler operation. As a balanced, mid-range Kv option in the 17-series, it delivers practical punch and durability, making it a solid upgrade for Traxxas X-Maxx and Arrma 8S vehicles and pairing well with the Mamba XLX2 ESC.

Overview
The 1721 Sensored Brushless Motor, featuring a 1260kV rating, is the latest high-performance offering from Castle Creations designed specifically for surface applications. This powerful and efficient motor delivers exceptional speed, torque, and acceleration, making it an ideal choice for serious large-scale bashers who insist on top-tier performance. Crafted with precision-machined components, high-strength magnets, and advanced winding techniques, this motor ensures reliable and consistent performance in the most challenging conditions.
Featuring a 4-POLE 12-SLOT design, the motor boasts exceptional efficiency while generating less heat, allowing for prolonged use without performance degradation. The optimized design eliminates the need for mechanical timing adjustments, as its sensor alignment method guarantees uniform timing and torque in both directions. Additionally, oversized NMB bearings along with a vibration dampening system maximize bearing life, making this motor a superb choice for rugged environments.
High-temperature grade neodymium sintered magnets paired with a robust Kevlar wrap reinforce the rotor’s integrity, enabling it to endure harsh running conditions. Proprietary winding techniques ensure a stator assembly with minimal resistance, resulting in cooler operation during performance. The 1721-1260Kv is the 'sane brother' to the 1721-2400Kv, designed for speed with a more moderate Kv that still delivers impressive power. It serves as an excellent upgrade for the stock 1717 size motors found in popular vehicles like the Traxxas X-Maxx and Arrma 8S.
For optimal performance, this motor pairs seamlessly with the Mamba XLX2 ESC, which is available for purchase as a combo. Experience the remarkable capability of the 1721-1260Kv Brushless Sensored Motor and elevate your large-scale bashers to new heights.
