Having not owned any alternatives I can't say if any are superior, but I've had the Yamaha side cases on mine since my Super Tenere was new two years and 33,000 miles ago, and they've been exemplary. They go on and off the bike in seconds, are plenty tough yet light. They've never given me a femto-second of trouble in all the time I've owned them, and they've been on the bike damn near every mile it's rolled. I don't even bother with the Yamaha bag liners I bought for 'em. I simply pack 'em up, and then pull them off and carry them like suitcases wherever I stay for the night.
Lots of folks have written negative things about the Yamaha side cases, but for the most part I've found many of those folks have never actually owned a set. There has been a lot of static about the locks, but if they are properly installed (with Loctite on the screws) and then occasionally lubricated (and I mean about twice a year, with the proper plastic-safe lock lube), I have found they are completely trouble-free and reliable. Nice thing, too, that they use the the bike's ignition key
They hold all I've ever needed to carry on long, multi-day trips, and if I need more space one of my two MotoFizz bags on the AltRider rack has been sufficient. They also make great stools when off the bike, too. The cases mount solidly and tuck in tight to the bike, keeping it about as narrow as it can be with hard cases onboard. Mine have held up to tons of abuse in the past 24 months. I'd gladly buy another set.
Just my two centavos...
