This ATV is a 2009 Honda Rancher AT 420 EFI 4x4. (TRX420FA) The Rancher AT is very different from the regular Rancher ES and S.

All other Rancher models have a solid rear axle and don't ride nearly as well as the AT. The AT features a completely automatic transmission (similar to the Rubicon/Rincon - with the option of electric shift at the flip of a switch). Basics of this bike include: · 4 Stroke 420cc ultra reliable Honda engine with Electronic fuel injection (EFI) · Electric start · Reverse · 5 speed electric shift or switchable to full automatic transmission · 4x4 on demand 4 Wheel Independant suspension
