I just ordered some Genmar risers from RLMotorcycles.com out of Georgia. Ordered on the 24th, received on the 27th, with standard shipping. No problems. Total to my door was $90.85.
And I'm liking the risers so far. The accelerator cables do barely kiss the fairing very at full left lock, but not enough to scuff anything. The appearance on the bike looks factory, and took about five minutes to install. I took a short ride on it, but need to take a longer trip to really evaluate the improvement in comfort.
