Yeah, I got the monster Krauser setup on my busa. I wouldn't be mounting any hard luggage to a 99-00 busa if it were me, unless you put on a 01-on steel subframe. You can get GIVI for the busa. But the rack will not be made by GIVI. THere are 2 options for mounting GIVI, 5 stars and SW MoTek. The 5-stars mount also adds a top rack for a top box, and the top rack is manditory for the install. The SW Moteck is a side case only install, and the side case MOUNTS are also quick release. They allow almost any GIVI case to be mounted. The Krausers can be side only or add the top rack option. I chose side rack only.
SW Motech racks at Riderhaus:
The site doesn't mention availability for the Busa, but they are available. You need to contact riderhaus directly for them.
Finally
I ordered my Krausers from riderhaus.com and they are an excellent business. Cost was $519 delivered, and I got them in 3 weeks.
As stated above, the L-P Superpole pegs are great and relieve the knee cramping.
