What Front Rotor Should I Choose?

When purchasing Warp 9 Supermoto wheels you will see the option for “Front Rotor Type”. The three options are: a stock-sized front rotor, a 320mm fixed rotor, or a 320mm Apex floating rotor. Here is a breakdown of each option.

Stock Rotor (No Bracket) – This one is pretty simple. It’s a stock size front rotor, meaning the same size your bike came with from the factory. This is a good choice for those looking to swap from their dirt wheels to their street wheels with ease. With this option, you don’t need to relocate the caliper so you can swap back and forth without removing and replacing any extra parts. PROS: Easiest option for swapping between wheel sets. CONS: Not your best braking option which may be important to you now that you’re riding your dirt bike on the street. Will heat up and potentially warp easier than an oversized option.

320mm Fixed Rotor with Caliper Relocation Bracket – This rotor is an oversized 320mm front rotor that comes with a bracket to move the caliper out to accommodate the larger rotor. This is the “standard” on a Supermoto conversion. The reason for a larger rotor on Supermoto’s is more braking surface means better braking and less heat. Less heat means less chance of warping the rotor. PROS: Better braking from larger surface contact. CONS: Not as easy to swap back and forth and may still get hot with excessive or hard braking.

320mm Apex Floating Rotor with Caliper Relocation Bracket – Like the Fixed Rotor option this rotor is also oversized and includes a bracket. The main difference is it “floats” by way of being two-piece. A fixed rotor is a solid piece of metal, whereas the floating rotor is two parts. The center that mounts to your hub and the braking surface that contacts the pads. So why pay more for a floating rotor? Performance! The number one reason why you would want a floating rotor is you are looking for the most stopping power. When you grab the brake lever it creates a hydraulic force that squeezes the pads onto the brake rotor. A floating rotor has the ability to conform to the pads giving maximum rotor to pad contact. This happens even when a relatively small amount of force is applied. PROS: The BEST braking power you can get on your Supermoto and the least likely to warp from excessive heat. CONS: Not as convenient when swapping from dirt to street.

In summary, no one option will be the best fit for everyone. You’ll need to weigh the pros and cons of each to determine what makes most sense for you. This is why we give you the options and the knowledge to make the best decision you can for your Supermoto conversion!
