Yamaha reinvents the
four-seat UTV with the all-new Wolverine X4 Special
Edition, an adventure
machine with new levels
of off-road capabilities
and on-trail comfort.
Undo five plastic rivets to remove the engine cover with four cup holders and access the 847cc
inline twin. Yamaha tuned the X4 engine for smoothness and torque. It has 47-percent more
torque than the 708cc Wolverine DOHC single. Two 82mm pistons ride on an 80.2mm
