There are usually two reasons to replace the brake discs on your bike: either it’s done out of necessity, when they are too worn or there has been a problem; or they’re changed with the aim of improving the performance of the braking system of our motorbike. In both cases, many users consider the possibility of opting for oversized discs. That’s to say, larger discs than those fitted on the standard bike. But… Is it OK to do this?

To understand this question, we have to look at one of the most important characteristics of this component: its diameter. As this is directly related to braking power, there’s a simple rule to keep in mind: the larger the diameter, the greater the braking power. This is because the distance between the disc axle and the wheel increases, as well as the point at which the caliper bites the disc, which means that the lever arm increases and more force can be applied.

Therefore, in order to know if it’s really convenient to fit oversized brake discs, we have to consider how we’re going to ride our bike. If we’re talking about a scooter or a naked bike that we use every day to get around town, it would generally not make much sense to opt for these discs. However, if we’re planning to ride on circuits or long trips through mountain passes, instances when a higher performance is needed, it would be advisable, or it could be beneficial, to use them.

Another important aspect to take into account is the braking system fitted as standard on our bike. If you find it isn’t so efficient, it may be advisable to replace it and fit oversized brake discs, regardless of how we intend to use our bike.

If you’re thinking of changing the discs on your bike, visit the “On-line catalogue” section of our website, where you can enter the make, model and year of your bike and the platform will do the rest. You will be able to find both discs with the diameter of the standard ones for your frame, and oversized discs with caliper adapters.
