There is something about motorbikes that turns grown men into kids. When words fail them, as they often do, when they describe the beauty of the machine they own, you are sure to hear men imitate the thump of the motorcycle, especially when it is as unmissable as the one a Bullet has. Even the very articulate 67-year-old Hidesign founder Dilip Kapur did that more than once while discussing his passion for riding and his much-loved machine — the 1977-built 350cc Bullet.
