Check out the new Metzeler Sportec M5, it has lean indicator on its rear tyre. The indicator mark your lean angle, “1” pretty much you are up right, and “5” in a lean angle. Some says this is a “Chicken strip” indicator. Chicken strip is a mark in your rear tyre that shows your lean angle, obviously if you have thick strip (say only till mark no 4 on the above picture) that means you never use the tyre to its max lean angle; and you are a chicken.. hehehe
Seriously, this new sport tyre is a new tyre from Metzeler that according to Metzeler have been optimized and the total area of the tyre footprint at every lean angle have been up to an 8% increase, while improving also its shape and pressure distribution. Basically that means is that you can have more confident in leaning the bike. And you have the above mark as indicator on how lean you go in the corner. Some sort of indicator for “bragging right” if you ask me.. 🙂
Anyhow, just like the scratch in your knee slider, don’t use this indicator to prove how brave you are. For that go to the race track and record your lap time!
