In the realm of electric motosport, one name stands out for its innovative approach and unparalleled performance: Alta Motors. Their flagship model, the Redshift SM, is not just an electric motorcycle; it's a revolution. Launched in 2017, it pioneered the electric dirt bike segment and continues to set the standard for high-performance, eco-friendly off-road bikes.
The Redshift SM's appeal lies in its ability to blend cutting-edge technology with a traditional dirt bike's agility and fun factor. It's quiet, emits no emissions, yet delivers an exhilarating riding experience. But how does Alta Motors' Redshift SM stack up against its combustion engine counterparts? Let's delve into its design, performance, and sustainability.
The Alta Motors Redshift SM: Design and Aesthetics
At first glance, the Redshift SM is a mix of modern technology and classic dirt bike styling. Its sleek, compact design is Adele-special, with a geometric aluminum frame, and a muscular battery pack shrouded in carbon fiber. The swingarm is made of billet aluminum, light yet sturdy, adding to the bike's agility and maneuverability.
The 7-inch TFT dash is a standout feature, providing real-time ride data, including speed, battery level, and riding mode. The color display is crisp and readable, even in broad daylight, and can be toggled between 'ECO' mode for extended range and 'SPORT' for maximum power output.
The Powerplant: A Brushless Electric Motor
The heart of the Redshift SM is its 50.4kW (67.5 horsepower) brushless electric motor. This permanent magnet AC (PMAC) motor delivers instant torque, propelling the bike from 0-60 mph in a quick 3.2 seconds. It's densely-packed, offering a high power-to-weight ratio, perfect for tight trails and steep climbs.
The electric motor is paired with a 5.8kWh battery pack, providing enough juice for around 50 off-road miles on a single charge. Recharging takes approximately 2 hours using the optional fast charger, minimizing downtime during long riding sessions.
Suspension, Brakes, and Tires
The Redshift SM rides on KYB coil-over forks and a Sachs shock absorber, delivering 11.6 inches of front and rear suspension travel. This ensures excellent traction and stability on rough terrains. The brakes are twin 270mm discs with dual-piston calipers, providing confident stopping power.
The standard tire setup is WTB Verdict 80/100-21 front and.Options include Dunlop MX33 or DRT-F aftermarket tires for enhanced grip and control. The tires are mated to 21/18-inch Excel rims, ensuring the bike can handle the toughest terrains.
Redshift SM: Performance and Handling
The Alta Motors Redshift SM's performance is nothing short of impressive. Its electric motor provides seamless power delivery, with the bike launching from corners and accelerating through straights with ease. The 'SPORT' riding mode unleashes full power, while 'ECO' mode offers a more controlled, fuel-efficient ride.
The bike's handling is exceptional, thanks to its relatively low center of gravity and light weight (274 lbs). The Redshift SM feels agile, flicking through tight turns and bounding over obstacles, reminiscent of a traditional 2-stroke dirt bike but with the added bonus of electric-motor torque.
Sustainability and Maintenance Costs
Eco-friendliness is a significant draw of the Redshift SM. It produces zero emissions and has minimal noise pollution, making it an ideal choice for riders concerned about the environment. With low maintenance costs - no oil changes, spark plugs, or air filters needed - and a long battery lifespan, it's also lightweight on the wallet.
Moreover, the Redshift SM's energy efficiency makes it cheaper to run compared to gas-powered competitors. With electricity being generally less expensive than gas, and the reduced maintenance costs, the total cost of ownership is significantly lower over the bike's lifespan.
The Future of Electric Dirt Bikes
The Alta Motors Redshift SM is more than just a dirt bike; it's a glimpse into the future. It proves that electric powertrains can match and even surpass the performance of traditional combustion engines. Alta Motors' focus on innovation and sustainability sets a new standard for motocross and enduro bikers looking for an exciting, eco-friendly riding experience.
The future of electric dirt bikes is bright, and Alta Motors is leading the way. The Redshift SM is not just a bike; it's a statement, a testament to the progress made in electric powertrains and the potential for a cleaner, more exciting future in off-road motosport.
