"We like to describe them as a duffel bag with legs -- a simple way to add capacity without requiring side racks. Beta Bags hug the bike via the seat channel, yet stay clear of the exhaust (on most bikes). The bags solidly mount by three quick release straps, one around the rear of the bike, the front each to a passenger peg/bracket or sub-frame.
We've further refined our classic design for 2011. We gave the bags a Full access Crescent top zipper opening for full access to the contents. We added our Tough-Tek non-skid/non-scratch material to the bottom (the same material we use on our Tank & Tail Bags.) Silver interior accents for better interior visibility. We' ve enhanced the overall shape. We kept the ever so useful side pockets, Carry Handle, Duffel Mounts and the 4 outside compression straps, and the ultra-durable Ballistic Fabric Body.
Which bag is right for your bike? The width of the seat should match the width of the seat channel. Measure your seat and check the dimensions below.
Need help getting your bag installed? Our customer Mike Friday kindly uploaded a video (see video/photo box) that may help you. He's installing an Alpha Rear Bag on an '09 KLR 650. "
