From Honda: At the heart of the 2014 Honda FourTrax Foreman 4x4 lies the same 475 cc, liquid cooled, OHV, longitudinally mounted, single cylinder four -stroke engine which is kept in leash by a five speed transmission with reverse. For the 2014 model year, the engine has been slightly tweaked to deliver a better fuel efficiency. The unit is fed by a generous 3.9 Gallons (including 1.3-Gallon reserve).
