YT DECOY CORE 2 — Performance Where It Counts

With RockShox’s latest ZEB Select+ fork and Vivid Select+ rear shock, the DECOY CORE 2 offers elite suspension at a mid-tier price. It’s powered by Bosch’s 100Nm motor and 800Wh battery for max trail time and effortless elevation gain. The SRAM Eagle Transmission keeps shifting crisp under load, while TRP’s DH-R EVO brakes provide controlled stopping on the steepest chutes. DT Swiss H1900 wheels and the proven YT Postman dropper make this a dependable, high-performance rig for aggressive all-mountain riders.
