I was looking for an undertail and my buddy has 231973bikes's dual round light model on his 9R and it fits really good, color matches great, but like any other undertail you are going to spend some time with the dremel, hack saw, jig saw, or whatever on the undertray to get all the extra plastic outa the way. I e-mailed a few people who bought this model and this is what they had to say,
"hey sorry if its too late but the undertail looks great on the bike
and works great. however you will have to cut almost all of the
stock trunk and it was a task i wouldnt undertake if you have
never done one before but it is functional and looks great and i
can send you a picture of it tomorrow because it wasnt my bike
i installed it on but if you want i can get one to you later"
"Jake i have a 2007 ZZR 600 and it fits well. i wish i would have got the
one with two lights though. The lights do blink a little fast but not to
fast. I think the speed is ok. The light is not that bright its ok. but
my recomendation would be to go for the under tail that has two big round
lights. You will kno what i mean when you see it. Are bikes are the same
bike the 09 - 02 zxr is the same bike as the 06 - 08 zzr. If you have any
more questions let me know."
I have always wanted to try fiberglassing, so I went out and got some pink foam to make a mold, and some resin and mat from the auto store and gave it a go. It was defiantly a good learning experience, and in the end I probably spent $75 bucks on something that I will replace when I paint my bike, but it was still fun! Sorry for the filthy bike, I still haven't had time to clean it after my 4700 mile trip to CA and back.
edit - here is a picture of my friend's 9R on HWY1 in CA. That is one of the most awesome roads that I have ever ridden on.
