Alta Motors 2018 Redshift MXR Electric Dirt Bike: Shocking Performance Increase

Alta continues to push the envelope in the electric dirt bike market with its 2018 Redshift MXR, which boasts a massive power increase and a significant weight loss.

Alta Motors continues to push motocross technology forward in its own way, namely without the use of an internal combustion engine to power its motorcycles, and today the Silicon Valley based high-performance electric motorcycle company announced its latest and greatest effort, the 2018 Redshift MXR.

Alta claims that the 2018 Redshift MXR’s 350-volt electric motor, which is capable of 14,000 rpm, puts out 50 horsepower and 147 lb-ft of torque at the countershaft—that’s a whopping 10 horsepower and 27 lb.-ft. more than the 2017 Redshift MX’s motor output. This increased motor performance is facilitated via a new 5.8 kWh R-Pack that uses a new cell chemistry for greater energy density and increased performance while also operating at cooler temperatures than the 2017 battery pack. The R-Pack works in concert with software upgrades to give the 2018 Redshift MXR more power with greater consistency during a ride or a race, according to Alta.

“The 2018 MXR incorporates feedback from all of our factory riders, customers, dealers, and Press,” said Jeff Sand, Alta Motors’ Chief Design Officer. “We are committed to make the most compelling MX bike in the market, not just the electric market. The 2018 MXR is the pinnacle expression of engineering in service of rider control. Control gives a more exhilarating and fulfilling motorcycle
experience. The MXR delivers.”

The 2018 Redshift MXR features more than just a power train upgrade. Alta says that the new model is also 8 lbs. lighter and features upgraded suspension from one of the most recognizable names in the industry, WP. A fully adjustable WP AER48 air fork resides up front while a fully adjustable WP rear shock is located out back. In addition to offering greater adjustability to suit a broad range or rider styles and terrain, the WP components boast lower mass, contributing to the weight savings.

Other changes to the 2018 Redshift MXR include redesigned foot pegs with a more aggressive tooth profile. Alta says that the new pegs not only improve grip but also provide increased comfort via an adjusted riding angle, lower mass and better performance in the mud.

The 2018 Redshift MXR is also fitted with some of the most recognizes tires on the dirt bike market today, Dunlop Geomax MX3S tires, which have been developed in AMA Supercross and Motocross to deliver excellent handling and grip in a wide variety of terrain.

“We’ve updated and enhanced well over 20% of the parts on the Redshift, demonstrating Alta’s commitment to leading the development of electric motorcycles and producing the best motorcycle in the world,” said Derek Dorresteyn, Chief Technical Officer. “The 2018 MXR’s increased performance, better control, and lower mass all add up to more fun on the track or trail. When coupled with Alta’s revolutionary adjustable throttle mapping systems, the MXR delivers an unmatched capability to our riders.”

The 2018 Redshift MXR is priced at $11,995, and customers now have the option of purchasing a new Rapid Charger for $799 or the Standard Charger for $499.
