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.
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.
