You need not buy the Maxia as ANY Topcase will fit. Some will find the Maxia aestetically too large. I do not know if other sidebags will fit. The kit will contain the necessary hardware that Givi does not supply, and full color photographic copies detailing the installation, bolt location diagrams for each side and full written instructions. A limited number of kits are now ready to ship.
New hardware is included.
Simple install, remove the 4 bolts holding the bar clamp, remove the upper part of clamp, replace the upper part with your new and awesome clamp. These are sweet. These pics I took don't do it justice. The last pic is a shot looking down from the front of the bike. In the pic on the right, the cap on the left is the low-crown, strap version.
