Why I Chose to Install a Big Bore Kit on My YZ85

As an avid rider and owner of a Yamaha YZ85, I have always been satisfied with its performance and handling. However, after a few years of riding and gaining more experience, I began to notice that my bike lacked the power and torque needed for more challenging tracks.
