Hello and welcome to the site.
I'm unsure as to the release of the CB-1 in Canada, but here in the US, it was only available 89-90 and only in blue. The color of the CB-1 logo on the fuel tank went from black to red during those two years. The CB-1 was available for a few more years in Japan in various colors and then became the CB400SF (super four) as it is today. The bike is a grey import in the UK, meaning it's not officially imported by Honda and done so by 3rd parties.
If you want specs, check out this article:
http://www.hondacb1.org/reviews-motorcyclist0489.shtmlI'll be posting some more in a future section on the site. Just haven't had the time.
Troublesome areas when buying a CB-1 appear to be the regulator which can cause a battery to overheat and spill it's guts on the swingarm causing rust. A redesigned unit is available from Honda and also fits a number of other bikes, too. So availability is good. That's the only thing I've had a problem with, except the fuel pump. That went out at the same time as my regulator.
BTW, this site is based out of Florida, USA. The CB-1 is more popular in other countries than it is in the US, so I wanted the site to appeal to all.
