Wolfman Boulder Beta Rear Bag

Over ten years of evolution stand behind the Wolfman Boulder Beta Rear Bag. Its most distinctive features are the cavernous 60 liter capacity interior and how it mounts over the passenger seat without the need for a luggage rack system. The upper outer shell is constructed of ballistic nylon laminated over vinyl, while the bottom outer shell incorporates slipknot, ballistic vinyl and a foam laminate.

To gain full access the interior of the bag simply unzip full length top opening. Inside, you will find a removable clear waterproof organizer bag and 3 waterproof 200 denier nylon stuff sacks to keep all your gear dry.

This Duffel-Bag-With-Legs is now even more refined and ready for any adventure that comes your way!

Great fit on a '14 GS Just got back from a 4000 mile trip and the bag worked great. It did take me a while to find a strapping configuration that I liked but once I did the bag was well attached and there was never a concern that it would move around. It's a bit pricey but it does hold a ton of stuff and seems to be a very durable bag. November 3, 2014
Awesome bag! Like all of the Wolfman products I have owned, this bag is also great quality. I debated buying racks and cans for my GS, but the bag made more sense because of the ability to use it on different bikes. I can pack all my camping gear / clothes / etc in this bag! Setting off soon for a 2500 mile adventure ride, and have confidence this bag will do everything I need. June 2, 2014
Wolfman at their best I've had my bag only about a week now, and used it for a 3 day trip. Completely overloaded with stuff (shakedown run for a two week trip end of month) and it worked out great. Mounting strap system is very simple, and easy to hook up. I've attached a picture of mine mounted, but it's at an awkward angle. Mainly, because it doubles as a backrest now, :D. The bag IS HUGE inside. It tightens down great, looks compact, but holy moly.. 60L is MINIMUM, in my opinion. You may be able to throw in a few more. Security? Well, There isn't any. I've got a small cable lock running through one of the extra strap mounts, around a grab handle. Prevents someone from walking off with it.. in a hurry. As always, typical Wolfman quality. I'm glad I went with this and not hard luggage. April 21, 2014

Deon B: I purchased this bag on my KTM 1190 R for a recent tour over 8 days. Loads of dust and some rain and the bag held it's own very well, keeping the clothes dry.
I just felt that I needed a little more space for the trip and purchased a Wolfman roll bag to make up the little extra requirement, but admittedly I did over pack and the bag is by far large enough for all the stuff I should have take and a bit tight for the stuff I ended up taking.
Well constructed and easy to fit onto the rear with the straps ensuring a tight fitting cargo on the rear.
Well worth it!

A shopper asked: I have a 2008 Suzuki GSXR600, riding to Cali from Vancouver, Canada. Is this too big for my bike? The tail is wide but I don't want it to throw off my balance either! Other option... the Beta Plus? Maybe the Beta Duffel as well to pair with it? Thank you! Jul 19, 2014
