I was doing about 90 kph in the Ammamandapam - Mambazhasalai stretch near my house. I had to overtake a slow moving vehicle and so I casually moved to the right from behind the vehicle. I managed to get along side the vehicle but I underestimated the speed of the oncoming traffic. So, I had to brake very hard and I did that. I was wearing my helmet and when I wear a helmet I usually hear only about 60% of the outside noise. When I braked, I heard, very clearly, the tyres squealing. But, amazingly, the bike was absolutely stable - I could steer it clearly where I wanted even under that hard braking. Now, the tyres squeal only when they are at their limit of adhesion, when they are about to call it a day. I guess, it was the amazing chassis of my beloved Apache that was at work, beautifully, on that day.
