1977 Formula TT Season
The 1977 Formula TT Season was the first event in the history of Formula TT and was announced by the Fédération Internationale de Motocyclisme as the official world championship in those categories.
The Formula TT was founded in 1977 by the Isle of Man government and the Auto-Cycle Union to compensate for the FIM's withdrawal of the Tourist Trophy's world championship status and at the same time to popularize racing with production-based machines.
The winner of each class's race at the 59th Isle of Man TT also became the TT World Champion in that category.
Class-System
- The Formula TT was divided into three classes in 1977.

TT-F1 Class
The TT-F1 race was ironically won by Phil Read, one of the riders who had campaigned most heavily for the TT to lose its World Championship status. Read had vowed in 1972 never to return to the island. However, he did so in 1977, having been signed by Honda Britain for the Tourist Trophy.The race itself caused controversy. It was stopped after four laps due to deteriorating weather conditions. After three laps, Ducati rider Roger Nicholls led by 22 seconds. After the fourth lap, he pitted for refueling, while Read crossed the finish line and was declared the winner.
