We’re limiting our discussion here to bikes that are both on- and off-road capable rather than dirt-only or street-only machines. Even then there’s a huge range from small, light, inexpensive 250cc singles to large, substantial, expensive continent-roamers with engines five times as large. And while there’s some temptation to think one choice more righteous or refined than another, that’s rubbish. It’s a matter of finding a bike that suits the kind of riding you do and understanding that the bike itself will most likely shape the adventures you seek out. The rider on a 250 may well ride up rocky single-tracks that the 1200 owner will never explore. On the other hand, the rider on a bigger ADV machine may roll up the kind of cross-continent mileage that few 250s will ever see.
