I think the difference with cars is that manufacturers make many more of them. Building bikes is still a very manual process with a lot of human touch, but waaaaay more options available. You see something similar with mountain bikes vs. dirtbikes. How can I get a 300lb machine with full suspension and an entire combustion engine for $3k and an FS MTB, with a fraction of the parts costs the same or more? Well, Honda probably make 50k CRF250s a year or something, and Norco make maybe 1/20th the number for any particular product line?
