Took me a minute to realize that you have 2 Valks - since the one in your sig pic isn't an IS trunk!

Yes, the lower part is still available, but expensive new. You can get it from Honda for anywhere between $970-ish and $1400-ish, depending on your paint scheme. I'm guessing this one is for the black bike, so it's probably the cheaper.

Shop around - you will find that there is some variance to what you'll pay for OEM parts, and you can save some $ if you spend some time.
