1967 Isle of Man TT

Five races, in different engine capacity classes of 50, 125, 250, 350 and the 500 cc Senior TT, made up the second round of the FIM World Grand Prix motorcycling championship season (now known as MotoGP).

[1][2] Mike Hailwood, on the four-cylinder Honda RC181, duelled with Giacomo Agostini's MV Agusta 500 Three.

At the halfway pit stop of the six-lap race, Hailwood had cut Agostini's lead to a couple of seconds, but he then lost time adjusting his twist grip back into place.

Then disaster struck Agostini on the mountain section when his chain broke at the Windy Corner.

His lap record stood for eight years, and was only beaten in 1975 by Mick Grant on an improved circuit riding a larger-engined Kawasaki KR750 cc.
