FIRST LOOK: 2018 Alta Redshift MXR | News

Alta Motors has unveiled the all-new 2018 Redshift MXR, now equipped with 50hp, 147 ft-lbs of torque, and a recharge time cut down to 1.5 hrs.

Designed to compete with a modern 350, the MXR comes equipped with 50HP and more torque than its predecessors. The 2018 MXR Performance Maps allow the Redshift to be just as capable as a novice trailbike as it is a professional MX2/Lites class motocrosser.

The 2018 MXR takes riding to the next level with its 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.

Alta’s Redshift MXR is powered by a water-cooled 14,000 RPM motor. 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.

Map Options

ECO
A traction map that offers the best range profile. Also a great map for just starting out.

SPORT
Performance profile engineered to line up with 250f race machinery.

PERFORMANCE
Similar traits as the Sport map but with more bottom end and traction – it also makes a great starting gate map

OVERCLOCKED
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.
