2012 Yamaha Stryker Totally custom even before you customize it. The Stryker is the coolest bike to roll of the assembly line since the Raider took the industry by storm. With its raked out front end "fist in the wind" riding position, this bike is pure attitude. and with an 80-cubic-inch V-twin, and a beautiful final belt drive, the Stryker churns out plenty of low-and torque that gets to the ground in a very satisfying way. It's time for an attitude adjustment.
