I have the Alt-Rider complete system, I've had the upper and lower bars installed for several weeks and finally received and installed the center reinforcing bars last night. They have an excellent fit and I can check the oil and change the oil filters with them on. You have to remove the LH or RH upper bar in order to remove any plastic body parts but they take less than 5 minutes to remove and install. I have tipped the bike over twice and the upper bars have done their job both times, I figure the bars have already paid for themselves. To be fair, I didn't really even look at the other bars, I had to wait until June to get my bike and the bars arrived about two weeks after I got the bike, so the back order wait wasn't an issue. I've said this in another topic and I'll say it again, If you are going to ride this bike hard, you need to install somebody's crash bars, especially upper bars.
