You may have noticed that some Maxxis tires have yellow logos and others have white logos, the difference in color designates whether the tire is OEM (stock on a complete bike) or not. If your bike comes with Maxxis tires they will have white logos and will most likely be a dual compound tire. If you purchase a Maxxis tire it will come with yellow logos. It's also worth noting that if an after-market tire doesn't specify the compound on the side wall then it will be a dual compound tire.
