This is mine. The bike started it's life as a 1990 ST50. I've had it for almost eight years now, and it went through quite a few changes.
The current engine is a homebuilt 124cc twin cam: takegawa 54mm stroke crank, 54mm bore, Daytona DOHC head, Daytona 5 plate wet clutch, takegawa 5-speed gearbox, etc...
The forks are shortened honda nice forks, custom made hub for disc brake, 4" honda CY50 rear rim, takegawa Hyper street down exhaust, altered seat, rev counter and temp. clock, and quite a few smaller changes. I've put CT70 decals on, just because I like the look of them, and they're different to what you would usually see here in Europe.
I also have a UK spec original 1972 ST50 K1. Untouched and as is, just over 2000 miles, the only thing I recently did was build a 'stealth' engine for the bike (not in pics yet) . Honda based, 4 speed semi, 88cc kit, 70 head, uprated oil pump, C90 clutch, 18mm carb with original air filter and exhaust. Looks standard but goes quite well.
My third dax is an original 1973 ST70 Lady Dax. needs some TLC, but I'll probably keep it as it is
Cheers,
Godfried
