Chase finished runner-up to Levin's Billy Frank in the 12-14 years' 125cc class at the junior nationals last season, but he will now step up to tackle both the 15-16 years' 125cc and 14-16 years' 250cc categories this time around.
The year 10 pupil at Tauhara College in Taupo, Chase is confident he can cope with tackling two classes, a mission that will require him to endure 14 races over the weekend.
"I'm feeling very fit at the moment. I train hard," he said.
"I have stepped up my training this year and do a lot of pilates, yoga, gym work, mountain-biking and riding my KTM motocross bike. There's no time for school work," he laughed.
"I feel pretty happy with how I performed at the senior nationals and was pleased to finish fourth overall [just 16 points off gaining a podium position]. I was too young to race against the seniors last year and this is a good result first time up."
Although among the youngest of competitors in the senior series, Chase showed just what he could do, even without full factory support or a big budget.
His lap times during the senior nationals were typically less than 700ths of a second slower than the eventual champion, Rotorua's Cameron Vaughan, and when his starts let him down and he found himself clogged up in traffic near the back of the field, he still managed to battle through and achieve placings among the top five or six.
"I had to take a few risks and be pretty aggressive to get through the traffic," he admitted.
"I know it won't be easy in the junior nationals either. There are a lot of good riders."
