The New Zealand Classic Motorcycle Register (NZCMR) is a series of five rounds from February to November, starting with the festival in Pukekohe which attracts up to 450 riders.
Other rounds are held in Taupo and Hampton Downs, with collective points deciding the championships.
While the classic motorcycles were the Grand Prix crotch-rockets of their day, one would think in today's scene that owners would race somewhat conservatively on their pride and joy.
Not so, says Tate, who had a few crashes among his wins.
"It's probably just as aggressive as the modern stuff. Most of them are very competitive."
He shows no signs of slowing down in the sport where he started in BEARS Racing, even as replicas are slowly replacing the originals in certain classes.
"You do get some parts [new], but they're all to the original specs ... Classic racing sort of developed [for me] it just grew and grew."
Tate also rode in the NZCMR series for Suzuki post-classic class, not to mention the Australian events, Paeroa Street Circuit and Invercargill's Burt Munro Challenge in recent times.
He is now looking forward to the return of the Classic Class at the 60th Suzuki Tri-Series around Wanganui's Cemetery Circuit on Boxing Day.
While registrations are hovering around the 20 mark, the classics should still prove a popular sight for fans on the day.
