D4---Empulse-20150901Building on the innovative design and engineering that produced the fastest American electric motorcycle at the 2015 Isle of Man TT Zero race, Victory Motorcycles has introduced the 2016 Empulse TT, the first all-electric addition to the Victory line up.

The Empulse TT is a fully electric road-legal streetbike that is as capable of carving tight lines on twisting roads as it is powering the daily commute.

Building on Victory Motorcycles’ focus on performance, the Empulse TT features a sportsbike-style aluminum beam-frame, adjustable suspension and strong brakes.

With advanced technology this unique new motorcycle delivers outstanding overall performance, zero-emission output and has a torquey electric motor.

“We have always been known for great handling and power, so the Empulse TT is an ideal fit in the expanding Victory lineup,” said Victory Motorcycle Product Director Gary Gray.

The key features that allow Empulse TT to deliver a sporty riding experience include: fully adjustable suspension featuring a single rear shock and inverted front forks; dual-disc front brakes; lightweight cast aluminum wheels; the greatest lean angle in the electric class; and a sportsbike-style riding position.

The Empulse TT shares some DNA with the original Brammo Empulse R motorcycle. Victory has been working with Brammo since 2011, but in January 2015 Victory’s parent company, Polaris Industries, acquired Brammo’s motorcycle assets. Since then, Victory engineers worked with the Brammo product team to achieve improvements in battery capacity, display function and handling.

The Victory Empulse TT is capable of top speeds over 100 miles per hour (160 kilometers per hour) and it has a high-capacity 10.4-kWh battery. The bike has a built-in battery charger and an easily accessible SAE J1772 plug atop the bodywork to the front of the seat.

The bike’s Brammo Power Lithium Ion battery fully charges up in just 3.9 hours using a Stage 2 charger (available as an accessory utilizing a 240-volt outlet).

In typical riding, the Empulse TT battery provides riders with a range of about 65 miles (104 kms) and a range of 100 miles is possible with throttle management and use of the bike’s regenerative charging. In preliminary testing, the bike demonstrated a Motorcycle Industry Council (MIC) city range of 94 miles (150 kms). The bike delivered an MIC “combined 70 mph [112 kph] highway and city range” of 57 miles (91 kms).

Riders can make the most efficient use of the battery’s 10.4-kWh of electricity by using the six-speed gearbox. Shifting and downshifting helps to create regenerative power (when the bike is under deceleration) and also produces a feeling similar to the compression braking that riders experience on petrol-powered motorcycles.

The clutch only needs to be used when shifting between gears, not for taking off or coming to a stop. To take off from a stop, the rider simply needs to twist the throttle to unleash the liquid-cooled electric motor’s impressive torque.

In the Empulse TT’s proprietary transmission, neutral is found between 2nd and 3rd gear. A rider can leave the bike in 3rd gear for most riding speeds and conditions. To begin riding, a rider can simply turn the bike’s power on, select 3rd gear (without the clutch), twist the throttle and go.

Not all competitive electric motorcycles have gearboxes, so the Empulse TT gearbox gives the bike a significantly sportier feel and it enhances a rider’s engagement with the bike.

In everyday riding conditions, the Victory Empulse TT can be operated in Eco mode, but it also has an optional Sport mode for high-performance riding. In Sport mode, 20 percent more battery power is released to the motor, resulting in enhanced acceleration.

Sport mode also increases the amount of regenerative braking – or “regen” – that further increases the feeling similar to compression braking when the rider rolls off the throttle. Regen uses the inertia of the motorcycle to return energy from the motor back into the battery pack. To select Sport mode, a rider presses and holds the start button for one second.

The bike’s LCD data display features a speedometer, tachometer, gear indicator and clock. It also displays the battery level as a horizontal bar accompanied by the percentage of battery energy remaining and provides an estimate of remaining riding range.

Genuine Victory Accessories immediately available for the Empulse TT include Victory performance forks, frame sliders, tall and short windscreens and panniers.

The new Victory Empulse TT electric motorcycle is scheduled to be available for purchase in the United States in late 2015.
