1991 - 2009
While the Italians continued to dominate the smaller classes, Norton held their considerable challenge at bay in the 1952 Senior and Junior races.
Duke made it four TT wins in succession with yet another start-to-finish victory in the Junior.
Duke was the clear favourite to make it five in the Senior, especially when he led for four laps. Dramatically, he then pulled into the pits and calmly got off his Norton to retire with severe clutch trouble, which left the others to fight it out.
Armstrong was determined to uphold British honour and slowly but surely he pulled away from rival Graham on the MV, his luck holding when the primary chain broke on the Norton as he crossed the finishing line!
The four-lap Lightweight race once again turned into a Guzzi benefit, Fergus Anderson breaking the race record on his way to victory and Bruno Ruffo the lap record.
The Ultra-Lightweight race was increased to three laps and provided Cecil Sandford and the MV Agusta with their first TT victory. He led throughout and achieved the first under 30-minutes 125 circuit when he averaged 76.07mph on his second lap.
