I just downloaded a PDF Service Manual and have seen a picture of what I think you are talking about:

If what you're referring to is at the end of the red arrow then it is definitely a helmet tether cable. I'm thinking if it doesn't fit under the seat then it may be long enough to push out under frame further down.
Also, check the third post down:
