How Much Does It Really Cost to Own a 125cc in the UK?
CBT, licence, insurance bands, tax, fuel, service, tyres and gear — with example monthly totals.
The sticker price is the easy bit. What surprises most new riders is the running side — insurance bands, the cost of a decent helmet, the CBT renewal that creeps up every two years.
Here's the honest, all-in number for owning a 125 in the UK, broken down so you can build your own version.
