Should be about the same in the long run... but the only real differences I can see from pics and specs from websites, is the gas tank size, lack of 'rear rack', different kick starter designs, and a slight different frame design on the 2... the Storm has a 12L gas tank, WILL only has an 8L gas tank... Storm comes with a Rear Rack, WILL does not... both have the same speedo/cluster design...
