For a 50-year-old to be considered a contender for New Zealand's glamour superbike crown is one thing, but to be battling alongside his own children in the races is quite something else and that's what will happen this summer.
Also racing on identical Honda CBR1000SP1 superbikes will be his two sons, 24-year-old Mitchell Rees and 22-year-old Damon Rees.
Damon won the New Zealand 600cc supersport title this season and is looking forward to stepping up to the 1000cc version of the bike in December.
Mitchell made his superbike class debut last season and finished a creditable sixth overall, but this summer will be the first time that all three men will be on the same starting grid.
"I've got the passion, I've still got the ability and I've got the bikes to get the job done ... so why would I quit now?" laughed Tony.
"I was originally just going to be on the sideline to assist my boys, but I was talked into giving it another crack myself and why not?"
In preparation for his novice year in the superbike class, Damon has been building up his strength and experience in recent months by tackling some of the best riders across the Tasman.
He missed the opening round of the Australian superbike nationals "because of a clash of dates", but raced with success at rounds two, three and four, before crashing out of the fifth round of seven at Morgan Park Raceway, south of Toowoomba, just over a week ago.
It means he'll now be sidelined with injury for several weeks, but expects to be fully fit and raring to go again by the start of December.
"I think he impressed a few people, because everyone there could see he was doing it on a shoestring. Brother Mitch was booked to head across and support him and so, with Damon now sidelined, Mitch will take his place at round six (at Sydney Motorsport Park) this weekend."
Meanwhile, the Rees trio are taking nothing for granted ahead of the New Zealand summer season.
"I'm expecting good competition (for the superbike title) from Sloan Frost, Alastair Hoogenboezem (Christchurch), Jayden Carrick (Whanganui), Hayden Fitzgerald (New Plymouth), Daniel Mettam (Pakuranga) and Taupo's Scotty Moir, among others, so I'm expecting it will be pretty hot on the track again this summer," said Honda team patriarch Tony.
