First off, the power. The ’18 model gets a new battery made by Sony (previously Samsung) and it is claimed to hold 50 percent more power. It is rated at 3.9 kWh, which gives the rider an estimated 1.5- to 2-hour range. But that varies wildly and the presenters made it clear that many factors, including the size of the rider, the mode selected, the terrain, the aggressiveness of the rider, all contribute to the range. To put in terms of a gas bike, the engineers claim that it has about 25 hp and makes 42 Nm of torque, close to what the KTM 250 EXC-F makes.
