Can I buy a motorcycle on many installments free of interest?

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

If these payments are without interest then there is no harm even if the price of the motorcycle with installments is more expensive than its price on the spot; this is, of course, if you are buying directly from the owner of the motorcycle. 

Allah knows best.
