Just put this on my sv650. Fits perfect and looks good. Zippers are good quality and the bag is tough. Perfect for school/work. It can hold about 2 books, laptop, a bottle of water, a change of pants, wallet and cellphone. Also has a key chain that connects to a quick disconnect inside the bag. This is the coolest feature to me. Another cool feature is the built-in rain bag, haven't used that yet.

Bag was $35 from Motorcycle superstore. Perfect bag for getting around the city. Installation takes 2 minutes and it takes 20 seconds to remove it from the bike. Handle works well too, it looks like a briefcase when carrying it around town. Only downside is no shoulder strap, but that's ok for the price.

Highly recommended for the city commuter.
