Frame & Swingarm

Every component of the Redshift chassis and drivetrain is designed from the ground up by Alta's engineers to achieve maximum strength and efficiency per pound. By refining and combining off-the-shelf concepts, we increased the functionality of each element of our motorcycles and simultaneously reduced weight, build complexity, and potential for failures. These innovative designs give the Redshift the strength riders need with the speed and agility riders desire.

The Redshift Bulkhead—the chassis's core—functions as the outer motor casing, the cooling circuit for the motor and inverter, and the transmission case for the gear reduction. This single piece of aluminum is also the main structural hub, connecting to the rear suspension, the airframe, the forged chassis, and the trellis skidframe. The integration of these elements is coordinated by strength, weight, and stiffness metrics set to produce optimal ride and compliance characteristics across all lean angles, and terrains. Traditional, siloed disciplines would make this outcome impossible, but Alta’s integrated engineering teams and proprietary development tools make such parallel processing possible.
