Not a lease. They are a 48 month loan with last payment being a balloon payment. Many states do not allow such transactions. A current example; a $16,600 machine financed for 48 months which has a final payment of $5,224.00. That last payment is accrued interest and any remaining principle owed. Monthly payments are lower than a traditional loan however overall payments result in higher overall costs. There is no guaranteed buy back - you are buying the bike and owe all that is due.
Hmm, as dlong described the financing arrangement, it sure sounds alot like the cars I've leased in the past.
