Motorcycle tire break in – myths, facts and how to do it right and fast! When buying new motorcycle tires surely many riders already noticed it. On the label of the tire a break in phase is prescribed, in which strong acceleration, extreme lean angle and too strong braking is to be avoided. The tire retailers are also recommend you a break-in phase of your new motorcycle tyres…
Motorcycle Tire Break In – The Reason Why It Is So Important!
The new tire tends to be slippery. This is due to the fact that the rubber is cold and on the other hand, that the surface of the tire is still closed and smooth even in the micro-range. If you look at a driven tire, you can see that it is rather rough, which is caused by the mechanical toothing with the asphalt. New tires do not yet have the rough rubber surface and are therefore more slippery as they offer less mechanical grip.

It is equally important to familiarize yourself with the new tire in the break in phase. Different tire models have different characteristics and influence the driving behavior decisively and feel differently in curves. Also the driver has to get used to the new tire …
Break In Time of Motorcycle Tires
The break-in period of motorcycle tires depends strongly on the tire and especially on its rubber compound. For example, soft sports tires are ready to use within a few kilometers (for example Michelin Power RS or Metzeler Sportec M7RR), racetrack slicks and racing tires even in a few corners or a lap (e.g., Pirelli Supercorsa). Hard touring tire compounds can also need 100 kilometers of break in time or even more, until they have the necessary mechanical grip to be able to work properly …
Most tire manufacturers recommend a break-in period of 50-100 kilometers, as most customers have theoretically traveled enough corners to activate the mechanical grip properties. Keep in mind, however, that 100 kilometers on the highway, for example, the tires do not break in properly and thus longer run in periods may be necessary! Curves are the key word!
My tip to break in the tire fast:
Choose a curvy road and simply go. Begin with not too much lean angle and acceleration and gradually increase your pace. Within a few kilometers, most modern road and supersport tires are ready to use at full power!
Myths around Break in the Bike Tires
There are also a lot of myths around break-in the tires. For example, the idea of grinding the tires with sandpaper and thus reducing the break-in time … Let it be! It’s pure waste of time! Tires are hard and resistant enough to resist a little grinding. You do not get enough force on the tire, as the abrasion is for example in hard acceleration or in curves!
Also the myth of the slippery release agent on tires widely spread! Yes, some years or decades ago, it was probably true that tire manufacturers used greasy / oily substances to get the tire out of shape. The so-called release agents then stayed on the tire for a while, causing reduced grip. Nowadays this is probably a myth for tires from top manufacturers such as Pirelli, Michelin or Metzeler because the molds are either coated with Teflon or polished and therefore no release agent has to be used.
Just believe it: NO big and serious tire manufacturer puts something slippery on the tire nowadays!
