The small segment of electrified motorcycles is about to get a large spark, as Alta Motors, once known as Zero Motorcycle, plans to come out with a new concept – an electric street tracker that will be road legal.

The San Francisco, Calif.-based company, already offers two electric models – the Redshift MX (motocross) and SM (supermoto) – and plans to add the Redshift ST concept to its lineup, which it will bring to The One Moto Show in Portland, Ore., reports Autoblog. The motorcycle will be a road-legal version of bikes that are designed to be raced on oval dirt tracks.

Besides the motorcycle’s seat height, which will be shorter than the companies other offerings at 31.5 inches, Alta didn’t provide any specifications behind the motorcycle’s powertrain. If the company uses items that it already has at its disposal, the concept will be powered by a 5.8-kWh battery pack and an electric motor that puts out 40 horsepower and 120 pounds-feet of torque.

With the same powertrain as the MX and the SM, the concept will have a range of around 50 miles on a charge and have a top speed of 80 mph.

The motorcycle manufacturer didn’t state how much the bike, if it were to go into production, would cost either. But as the company’s other bikes hover around $15,000, a price tag in that neighborhood shouldn’t come as a surprise. Alta did take some time, though, to tell Autoblog, that the ST won’t go on sale before 2018.

While the prospect of an electric-motorcycle with the styling of a flat track racer sounds promising, ponying up $15,000 for something with only 50 miles of range might be a tough sell. Still, Alta’s ST concept would be a good start to a segment that will hopefully expand.
