Today I got some 26x2.5 inch tires in the mail, went to install them and started with the front and realized that my motorbike isn't able to fit a 2.5 inch wide tire in the rear because of the direct drive chain. I went ahead and put one of my 2.1 inch tires on the rear that seems to have plenty of room and handles well on the muddy trails. Here's some pictures to give a visual explanation, I went ahead and added a pic of the new aluminum hand grips as well. They seem like better quality for when the bike is sliding in the dirt from a crash and what not, the plastic grips got wreaked from hitting the ground so much. Also cant wait to test out that new seat you see, VERY springy, doesn't seem like it will jolt my back as bad on the railroad beds.
