Should I check the MOT history before buying a 2021 Kawasaki Bx 125 Bmfan?

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

Do I need an HPI check when buying a 2021 Kawasaki Bx 125 Bmfan?
