You begin to depreciate your property when you place it in service for use in your trade or business or for the production of income. You stop depreciating property either when you have fully recovered your cost or other basis or when you retire it from service, whichever happens first.

The Internal Revenue Service allows taxpayers to deduct depreciation on vehicles used for business purposes, including motorcycles. Most of the time, deductions for a motorcycle or other business vehicles are figured using standard IRS rules based on time and mileage.
