Of course, there are some limitations to the Empulse R. Even though battery capacity has been stretched to more than 9 kilowatt-hours, it only gives the Brammo a range of 75 miles or so of backroad riding at relatively moderate speeds. High freeway speeds (80-plus mph) can bring that down to just over 50, while slow-speed city riding can extend it to more than 100 miles. Superior battery capacity and new technology costs money—Ducati 1199 Panigale-type money. The standard Empulse is suggested to sell at $16,995 before any electric-vehicle rebates or tax breaks that may be available, while the Empulse R with carbon-fiber bits (fenders, headlight and taillight assemblies) and upgraded suspension (fully adjustable Marzocchi fork and Sachs shock) is $18,995. That’s expensive, but with just 300 Empulses scheduled for production in 2012, this best current electric motorcycle may still be in short supply.
