Tekin Pro2 BL 2.5D 4100kv, 540, 1:8 shaft

The Tekin Pro2 BL 2.5D 4100kV with 1/8in shaft (TT2505) is a high-torque, 4‑pole brushless motor engineered for 2WD Short Course performance. Borrowing proven architecture from Tekin's 1/8th scale T8 platform, the Pro2 HD delivers exceptionally smooth power, precise throttle feel and strong efficiency. It is designed to be paired with the Tekin RX8 Electronic Speed Control and is rated for 2S (7.4V) LiPo systems.

Built around a CNC‑machined 6061‑T6 aluminium heatsink can, the motor stays cool under sustained loads, while neodymium sintered magnets and high‑purity copper windings maximise energy conversion. A rebuildable construction and high‑RPM ABEC5 oversized bearings round out a durable package suited to demanding short course racing.
