@izzy I was actually looking for a CB300 or 500 when I got this, but this was the only thing on Craigslist at the time that met the bill and I got super lucky and got it *really* cheap. Ended up doing 90% highway commuting with it, so it worked out (heavy enough not to be blown around, but not a 900lb Harley Fatboy or whatever where I feel like I'm riding a boat). I've never even heard of the 400SF, that really does look like it would be the perfect size!
