Robert announced that he was hoping to win the Isle of Man TT and North West 200 before he quit, and that he intended to focus on his sons, William and Michael, and pass his motorcycling experience to them. Robert continued racing until his retirement at the 2004 Isle of Man TT races .
On 8 February, 2005 he was the first person to be elected to the "Irish Motorcycle Hall of Fame". At the event, Robert announced that he was shortly to enter hospital to have his injured leg broken and lengthened, an inevitable conclusion to his 1994 Isle of Man TT accident. He also announced if all went well, he would love to return to motorcycle racing in 2006, sponsored by Patsy O'Kane in a last hurrah.
Robert actually came back out of retirement during the 2005 road racing season.
