This convenient, well-made waterproof bag is specifically designed for the tunnel of a Suzuki Burgman 650 scooter. It is secured by both velcro and straps/bolts. New over $200. Selling because I already have adequate storage on my Burgman 650. This bag would probably work nicely on the Burgman 400 and many other scooters. Please call or text Brian at 250-896-1046. (I seldom check for emails). In Saanich area. Thanks for looking. Cheers..
