After riding what he calls the "beast bike" for "Bbuddah - Hoga Tera Baap", megastar Amitabh Bachchan is eager to buy his own Harley Davidson.

"What is it with men and the sound of a mean machine. The roar of a speed car, the rush of air and sound in a double exhaust bike, that kick of acceleration as you push the pedal flat, that jerk of change on the Concord, when it was functional, as it went from normal to Mach 3 at 55,000 feet in the air! Is it the same with the ladies too?" Amitabh wrote on his blog bigb.bigadda.com.

"Soon after it was the adrenalin pumping beast bike, the Harley 'twixt my legs. And what a monster it is. I have to say though that having done it, and for the first time, it is an experience that now coerces me to have one of my own.

OOOOO! Baby!! It is another world as you stride all the leather and studs and white metal that surrounds you. Quite something!" he further wrote.

Meanwhile, age seems to be taking its toll on the 68-year-old.

"Running at 70 is a bit of a bother! You feel you can move with some fluidity, but no! The legs do not respond to what the mind is telling it to do and you suddenly realize that the weight of your body is not that lithe anymore," he wrote.

"So as I sit down on my 'blogespherechair' to fill in my adventures, I am cushioned with hot water bags and electronic heating devices to ease out the numerous folds of muscles, that had remained dormant and in retirement for a very long time," he added.
