The Redshift SM is the ultimate urban commuter. Built with the DNA of a race supermoto, our Redshift SM eliminates the incessant oil changes and maintenance intervals of its competitors. It’s street-legal, and a potent motorcycle on crowded city streets. Commute, race, and run errands on the Redshift SM.
HR 120V RECHARGE
The Redshift Bulkhead—the chassis core—functions as the outer motor casing, the cooling circuit for the motor and inverter, as well as the transmission case for the gear reduction. Additionally, it is the main structural hub, connecting to the rear suspension, the airframe, the forged monocoque chassis, and the trellis skidframe. All of this integration is coordinated with very specific strength, weight, and stiffness goals to produce the right ride and compliance characteristics at all lean angles, and under impact.
Alta’s liquid-cooled 14,000 RPM motor is pound for pound one of the most powerful in motorsports. It is optimized to the narrow width of the Redshift’s bulkhead and is precisely located at the roll center of the bike. This placement allows for the lowest polar moment of inertia in motorcycling – drastically minimizing any gyroscopic impediment to handling. The Redshift’s motor weighs 15lbs and puts out 42 HP at the countershaft and pushes power through a 3.5:1 gear reduction to deliver 120 ft-lbs of torque from a dead stop at 0 RPM.
Mile for mile, ther is no smaller, more compact, energy dense battery pack in transportation. The Alta Pack is waterproof rated up to IP67, is durable enough to handle shocks and vibes up to 20G, and is digitally self monitoring. Our stacked honeycomb architecture allows for extreme energie density at 185 watt hours per kilogram, combined with a unique thermal wicking system to shed heta faste than any other litium-ion transportation battery in production.

A traction map that offers the best range profile. Also a great map for just starting out.
Performance profile engineered to line up with 250f race machinery.
Similar traits as the Sport Map but with more bottom end and traction – it also makes a great starting gate map.
Maximum torque and power are available without restriction – if you have the skill to control it. Thermal limiting will protect the machine if you push too hard.
