Hey everyone I just bought myself my first bike! It's a 2009 ninja 250r special edition and I love it! Just wondering though, it didn't come with a manual and I'm finding a lot of different answers online. I wondered how often I should get my oil changed? Also I'm buying new gear cause mine is a little snugg and uncomfortable. I'm looking into some scorpion brand textile jacket and pants. Would it be worth spending the extra money on leather?
