As someone with a 125 autoclutch motor (that likely puts out less power than the one this new bike will come with) in a CT90 I can affirm you likely won't need the low range transmission (unless you're trying to haul some serious weight uphill). With the power my bike has it loses traction well before power becomes an issue. And it'll do 50-55mph before it runs out of gear. So those disc will be welcome additions to this old design. On the ease of dropping in a low range to the Cub motor/trans, of that I'm not so sure. But I can tell you the old Cub and CT motors weren't one in the same with the addition of low range. The trans housings appear different on the ones I have and one of the mounts to the chassis had to be relocated for CT use from standard Cub configuration (presumably to accommodate the casement changes necessary for the low range fitment). So with what would be added expense for an engine that's already plenty powerful for the application (that may not be selling in large numbers), I can't see Honda giving the go ahead. But I'd sure like to see it.
