The recruitment drive for T.T. 2009 continues with two more riders set to make their debut.
Belgian Marc Fissette and German Rico Penzkofer are the latest additions.
Fissette has road race experience - he finished second to Joey Dunlop at the Ulster Grand Prix in 1997 and made his debut at Macau last year where he was the highest placed newcomer in 9th.
In between, he has competed in the World Supersport and World Endurance Championships.
Penzkofer is another regular at both the World Supersport and World Endurance series. He finished second at the 2007 Macau Grand Prix.
Both will ride for the Macau Yamaha Racing Team in the Senior, Superbike and Superstock T.T. races.
