I am not sure what country spec they were but the NZ bikes were officially imported by Honda New Zealand and were full power models.

I was sponsored by a Honda shop at the time and the cranks that it blew were partially funded by Honda NZ as racer support/warranty (one was bad fitment).

My guess would be anywhere from 30 - 70 odd bikes were brought in.

Whether they were japan market ones or not i don't know.....
