The Warp 9 Atlas Sigma Direct Mount Stem is engineered for riders who want strength, precision, and adjustability in one clean package. CNC-machined from 7075-T6 aluminum, it’s built to handle the demands of aggressive e-moto and dirt bike riding. This stem fits MX fat bars (28.6 mm / 1 1⁄8") with the included shims, as well as Warp 9’s 31.8 mm / 1.25" bars for the Surron Light Bee. By moving your bars 10 mm forward, it sharpens control and handling feel, while the included spacer gives you the option of adding 20 mm of rise over stock height. Bolts for both low and high configurations are included, making it simple to dial in your setup. Strong, adjustable, and rider-tested — the Atlas Sigma Direct Mount Stem delivers confidence and performance every time you ride.
