...is a contradiction in terms. No factory has ever produced anything "custom".
Thank you. That is all. You may carry on now.
No, wait. I'm editing. That's not all. Here's my inspiration: the term "custom chopper". By its very definition, a chopper is "custom". Saying "custom chopper" is redundant - it can't be anything else. It's a bike that's been modified from the way the factory produced it. The same goes for bobbers and café racers. A bike that was churned out from an assembly line is a production vehicle. I don't care how many people call the Honda Fury a chopper, they will be wrong. What was chopped from it? The same with Harley Davidson's Street Bob. Nothing got "bobbed" off of it - it came from the factory that way. I would also include the Triumph Thruxton "café racer". They are all production vehicles (quite fine quality, I'm sure) which took styling cues from motorcycle customizers. I'm not saying there's anything wrong with this; my own motorcycle is sort of based on a street fighter, but it's really close to stock. Thus, I don't refer to it as a street fighter or as any kind of "custom".

Okay, I got pushed up onto the soapbox by hearing the term "custom chopper". I'm done. Stepping down from the soapbox now.
Now you may carry on with your day...
