Fourteen-time TT sidecar champion Dave Molyneux will return to the TT this year and says he has "high hopes" for his partnership with Patrick Farrance.
The pair last competed in 2010, finishing second in the opening race and were leading the second race before breaking down.
"We've got a good bike put together and we've got high hopes," said Molyneux.
Molyneux, 47, made his TT debut in 1985 and is the most successful sidecar driver in the history of the event.
His 14 victories make him the joint-third most successful TT racer ever, level with Mike Hailwood and only behind John McGuinness (17) and Joey Dunlop (26).
The Isle of Man racer also holds the ultimate lap record for the sidecar class, which he set in 2009.
Former world champion Farrance added: "I am really happy with the way things are going and I can't wait to get out there now."
The 27-year-old made his TT debut in 2002 as a teenager and said he is determined to earn his first TT victory this year.
"I have been on the podium twice but I am sure that a victory will rival or even better my world championship title," he said.
The pair will once again race a Kawasaki backed ZX-6R machine.
