My buddies and I are planning to go a motorcycle adventure next month and it might involve off-road trails. Just have to make sure that my 2015 Yamaha Fj09 Tracer is on tiptop shape once I pick it up. Do I have to replace the regular tires with dirt bike tires? What brand should I consider checking out? The owner said that he has a set of hardly used Maxxis Dirt Bike Tires in his garage and he is selling it to me for a cheap price.
