Designed to compete with a modern 350, the Redshift MXR comes equipped with 50 HP and more torque than its predecessors. The 2018 MXR Performance Maps allow the Redshift to be just as capable as a novice trail and woods bike as it is a professional MX2/Lites class motocrosser. The MXR requires no air filters, oil changes, or top end rebuilds, so you can spend less time wrenching on your bike and more time riding. Join the growing number of people that believe this is one of the most fun motorcycles ever built.
The Redshift Bulkhead—the chassis core—functions as the outer motor casing, and 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 chassis, and the trellis skidframe. All of this integration is coordinated with very specific strength, weight, and stiffness goals to produce the best-handling motocrosser ever made.
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 coupled with a very low counter-rotational mass 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 50 HP at the countershaft and pushes power through a 3.5:1 gear reduction to deliver 147 ft-lbs of torque from a dead stop at 0 RPM.
The 2018 MXR takes riding to the next level with our upgraded R5.8 Battery Pack. Alta’s new R-Pack demonstrates uncompromising commitment to super-dense battery systems for high-performance electric motorcycles. The R-Pack takes advantage of state-of-the-art cell chemistry delivering extended full-power range at cooler operating temperatures. The R-Pack sets Alta apart from the rest, delivering the most exciting motorcycle experience available off-road or in the city.

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.
