Honda quality has slipped.
No, I don't think there quality has slipped at all. I rate my CBR as one of my favorite all time rides. But it is exactly what I paid for. A very reasonably priced commuter bike, of very reasonable quality and performance. I'm fairly sure I got exactly what I paid for.
If I wanted to get better quality, I would have needed to fork out a lot more money, but then that is not a guaranty that it won't be completely trouble free. The CBR is a really good bike, and the quality is what I expected for the price paid. I've had to tighten the odd part, & pay attention to looking after it, but then that is normal maintenance on a bike.
