SW Motech, soft luggage made specifically for the Aprilia RS 660. It’s possible they would work with other things. In perfect condition, I’ve barely used them. Comes with all pieces. Cost more than $400 new. Please note in the pictures, I did cut a hole out of the center of the over the top connecting piece. The reason is that if you don’t cut that piece, the over the top part has to go over the seat, which is both very cumbersome and ugly. It’s also not as secure. The way I’ve done it, you can put them over the back of the bike, but underneath the seat and latch your seat in position over the strap. Much more secure, looks 1000 times better, somebody can still sit on the seat. If I were keeping them, I might consider taking it to an upholstery shop and having it professionally finished, but it’s not really necessary. Other than that, these are exactly like you would buy them from SW Motech, but a third of the price. They work really well, possibly the best soft luggage I’ve ever used on any motorcycle.
