Best for: Built for laid-back boulevard cruising and style-focused riding rather than outright performance or cornering agility.
Built for: A classic American custom cruiser with big V-twin torque, chrome styling, and a relaxed, thumping ride that prioritizes presence over speed.
Not ideal for: Not a good fit for riders wanting sharp handling, off-road capability, or a lightweight, flickable machine for tight cornering.

Riding a year

Based on the maker's published fuel consumption and tank size. Official figures come from a gentle lab test - most riders use 10-30% more fuel than this, so expect less range in real riding, and the last litres of a tank are reserve. Prices shown greyed are examples - type your own.
