"The whole idea - the whole foundation of it all was to make engineering fun," he said.
"There's nothing better to get students to enjoy a subject than to give them something that interests them."
Back then there were 14 students. Now there are more than 100 just at Feilding High School.
All up more than 200 come from around the North Island to race their bikes at Manfeild.
"We've had good success with employers who come basically looking for students," Mr Emmerson said.
"I mean what's better than going for an interview for a job and they ask you what did you make? Here's a motorbike, and album of photographs and a record of what I did. And a lot of the boys get the job straight away."
And one of those may be Caleb - who picked himself up from an earlier tumble to win his first race.
"Came through, got a good start and lead the race pretty much the whole way. Didn't lean over as much in the corner which meant I didn't crash which meant it was easy to stay upright."
This year's MiniMoto GP celebrated ten years of teaching students what Mr Emmerson says will always be sought after skills.
