REDSHIFT MXR


 
static1.squarespace.png

Designed to compete with a modern 350, the 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.

Map_Explanation_V2.jpg

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.

 
ALTA PACK
 The Alta Pack
 

The R5.8 Pack

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.

MOTOR
 

The Motor

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 42 lb-ft of torque at the motorfrom a dead stop at 0 RPM.

BULKHEAD
 

Redshift Bulkhead

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.

BODYWORK
static1.squarespace-1.jpg
 

Since 1973 Acerbis has been producing high-quality plastic bodywork and the company has worked with everyone from legends like Preston Petty to OEM manufacturers such as Yamaha. We're proud to partner with them to ensure that the Redshift’s bodywork meets our world-class standards in durability, quality, fit and finish.  

SUSPENSION

WP is a proven performer across every discipline of off road racing from amateur to international venues. Alta selected the WP AER suspension, which we believe to be the best air-sprung fork on the market, for the MXR for a significant weight savings and infinite tunability. The MXR also features an upgraded rear shock with improved valving and linkage dynamics, and additional weight savings from the short-body reservoir.

BRAKES

Brembo S.P.A. is the gold standard for high performance brake systems on motorcycles. Founded in 1961, the Italian company produces a range of products that can be found on motorcycles on the street and the trail. The Redshift MXR employs cast and machined Brembo calipers.

WHEELS & TIRES
RedshiftMXR_WHEEL.jpg
 

Warp 9 Racing is an American manufacturer of high performance motorcycle wheels. In a short amount of time Warp 9 Racing has gone from a boutique upstart to an OE supplier, offering some of the highest quality wheels on the market. We chose to work with Warp 9 Racing because their wheels are produced here in the US, and their exacting demands for quality and performance match our own.
