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

As a passionate motocross rider, I am always looking for ways to improve the performance of my bike. After riding my Yamaha YZ85 for a while, I noticed that it lacked the power and torque needed for some of the more challenging tracks. That’s when I started researching different ways to upgrade my bike and came across the option of installing a big bore kit.
