Victory Motorcycles has today lifted the covers off a �Street� version of the bike that Lee Johnston and Guy Martin rode to third and fourth in this year�s TT Zero race.
Named the �Empulse TT�, the bike is the first all-electric addition to Victory�s line-up since the Polaris Group bought the assets of Brammo earlier this year.
The Empulse TT features a sports bike-style aluminium beam-frame and adjustable suspension. It�s capable of speeds in excess of 100mph and has a range of 60mph when ridden in a typical manner. With throttle control and restraint, the range increases to 100 miles.
Victory claim the Empulse TT, which shares a number of components with the original Brammo Empulse R, has the fastest charging battery on the market. From empty, a full charge will take just 3.9 hours using a Stage 2 charger, which is available as an accessory utilising a standard 240V outlet.
The Empulse TT also features Brammo�s six-speed gearbox. As this isn�t something all competitive electric bikes have, Victory claim this gives off a �significantly sportier� feel.
There are two riding modes, �ECO� and �SPORT�, which are fairly self explanatory. In �Sport� mode, 20% more battery power is released to the motor resulting in better acceleration.
The bike will go on sale in the U.S. later this year, with global demand then being assessed before a sales plan is announced for Europe.
