520 Chain and Sprocket Kits for Street/Track Use – Kawasaki Ninja 400 / Z400

Replacing your OEM sprockets to change the final drive ratio of your motorcycle is a great way customize your bike’s performance for you.  By using a shorter drive ratio, you can dramatically increase acceleration at the expense of losing a little bit of top speed, making the bike a lot more fun to ride!
