First ZRX is my brothers, then mine, both are '99 1100's. '78 KZ400 with some engine work, and last, '70 SL175 K0. The 175 won it's class at the Barber Vintage weekend VJMC show.
More pics of the 175 and some of the restoration process are here: http://s424.photobucket.com/albums/pp329/wku88/SL175/
Those 1100's are seriously bada$$.
