Would I have a vintage bike as a daily driver? No, probably not. Riding a motorcycle every day where I live (which I do, by the way), is dangerous enough on a modern bike. Riding a bike here, without ABS, some kind of traction control, really good tires and handling, is not just asking for trouble - it's begging. But, if I lived somewhere else? Maybe...
If you have your heart set on something like the 650 Nighthawk, then, IME, some things to consider:
- Can you go to the Honda dealer and get parts for it? Like plugs, points(if it used them), and oil filters? Air filter (s)? Chain and sprockets? Here's a good one- clutch and brake cables? And carb parts - can you rebuild them, if you have to? 'Cause they
do wear out. Gonna have to do this pretty soon on my Sportster - which was the last of the carbed Harleys, in '06...
- All the rubber on it is
old. And rubber bits get brittle and crumbly. Can they be replaced? Those bits were
my main obstacle a decade ago, trying to rebuild a BMW R90 - and Beemers weren't made to be thrown away, either, like Japanese bikes.
- Tires. Some older bikes had rim sizes that you won't see any more - or the tires that fit them. I passed up a really cherry Moto Guzzi Le Mans a year or so ago for that very reason.
That said - If you can get parts for it; and you can wrench on it yourself? Yeah, go ahead, by all means.
