Here is another example, from Murphs which is tremendously cheaper and simpler, also without anywhere near as much rise or pull-back. Seems more like what you would be looking for. Doesn't include the bar, however:

I believe those are for the old Concours C10. I am not a fan of Murf's new website format. There doesn't seem to be as much for the C14 anymore either.
With the LSL setup, you can do almost anything, it all depends on the bars you choose to put on.
