“The Empulse TT was developed primarily as an electric motorcycle delivering a sporty ride,” said Victory Electric Product Manager Joshua Katt, “but with dual ride modes – ECO and SPORT – to choose from, and the addition of a gearbox, the Empulse TT is a versatile motorcycle that can be used for impressively sporty riding or as a casual commuter.”
The key features that allow Empulse TT to deliver a sporty riding experience include: a fully adjustable suspension featuring a single rear shock and inverted front forks; dual-disk front brakes that deliver confidence-inspiring high-performance stopping power; lightweight new cast aluminum wheels; the greatest lean angle in the electric class; and a sportbike-style riding position.
The Victory Empulse TT is capable of top speeds of over 100 mph, and it has a high-capacity 10.4kWh battery. The bike has a built-in battery charger and an easily accessible SAE J1772 plug atop the bodywork in front of the seat. The bike’s Brammo Power Lithium Ion battery fully charges in just 3.9 hours using a Stage 2 charger (available as an accessory utilizing a 240V outlet). The bike will fully charge in 8.9 hours using a regular household 120V outlet.
In typical riding, the Empulse TT battery provides a rider with a range of about 65 miles, 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. The bike delivered an MIC “combined 70 mph highway and city range” of 57 miles.
Riders can make the most efficient use of the battery’s 10.4kWh of electricity by using the six-speed gearbox. Shifting and downshifting help to create regenerative power (under deceleration), and also produce a feeling familiar to experienced riders of the compression braking on gasoline-powered motorcycles.
The rider only needs to use the clutch when shifting between gears, not for taking off or coming to a stop. When coming to a stop, a rider can leave the bike in gear, or choose to click the shifter down (without pulling in the clutch) to put the bike in neutral. 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 gears, and the transmission can be left 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” – which 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, which increases available energy. To select SPORT mode, a rider presses and holds the start button for 1 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 side bags that hold cargo.
The new Victory Empulse TT electric motorcycle is scheduled to be available for purchase in the United States in late 2015. Victory is in the process of determining global demand for the bike before announcing its international sales plan.
