The general consensus is that a classic motorcycle must be at least 25 years old. Another consideration of what constitutes a classic motorcycle is the simplicity of the bike itself.

Classic Car insurance generally kicks in for cars 20 years and older. However, there is also the UK Road Tax exemption on Classic Cars. When this was first introduced, a car needs to be more than 25 years old to be eligible. However now, due to a change in the rules, this only applies to cars built before 1973.
