leasing a bike makes complete sense if your in a position to lease and its not really your money. LOTS of big expensive bikes get leased, not by HD, Ducati, or Yamaha, but by independent leasing companies that will set you up with a Buggati or TVR , because in your company deal you get a car. Its not for people that cant afford to buy a luxury vehicle, its for people that don't have to. Maybe you get a car and your spouse also gets a car in your deal. If your single, have a car and a bike.
The even better part is the company front loads the heck out of the lease so they buyout is peanuts, if you choose you can have your toy for a fraction of cost. The company you work for has paid out the bulk of the value. This happens all the time, its just not for 95% of employees but when your at a point in your career, or work with more than one company, things are different.
