BMW MOTORRAD UK'S GUIDE TO THE 2017 ISLE OF MAN TT
The 2017 Road Racing season only kicked off two weeks ago, but already practice is well underway for what is undeniably the biggest event on the calendar, the Isle of Man TT.
The Isle of Man 'Tourist Trophy' is one of the most famous and prestigious motorcycle races in the world. Held on the Isle of Man since 1907, it runs on a 37.73-mile road circuit.
Instead of a traditional grid start, riders are sent off one at a time in ten-second intervals. As the race is a time trial, it doesn't matter who crosses the finish line first, but who completes the race in the shortest overall time.
Races are between four and six laps - with motorcycles coming in for a pit stop every two laps for fuel and rapid changes or fixes. The time spent in the pits is included in the overall time, making for a thrilling spectacle for those in the start/finish grandstands.
The most famous section is the Snaefell Mountain route, taking place across the highest parts of the Isle of Man. Because of the location in the Irish Sea, often one part of the course can be in blazing sunshine and the Mountain section can be foggy, wet and cold. Riders need to have incredible knowledge of the circuit's 264 corners and ride almost perfect laps to be in with a chance of winning.
