Beyond 20,000 RPM!
Apollo actually not bad, is India 2nd largest tyre manufacturer and sponsoring MU... HahaWow, even cheaper than my 'spaceship' Apollo.
From my experience with my cheap Apollo i can say;
1.Its going to be noisy.
2.It looses grip easily in wet.
3.It wears quickly.
Despite all the shortcoming, it does get me safely from point A to point B. Doing it at sensible speed of course.
