Wolfman Beta Plus Rear Bag

Wolfman describes 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.

A full access Crescent top zipper opening for full access to the contents. Wolfman added Non-skid/non-scratch material to the bottom (the same material they use on their Tank & Tail Bags.) Silver interior accents for better interior visibility plus new and improved raincovers. Wolfman kept the ever so useful side pockets, carry handle, duffel mounts and the 4 outside compression straps, and the ultra-durable Ballistic Fabric Body.


  • Seat Overhang: 5" 
  • Overall Width: 29"
  • Height (from top of seat): 9 1/2"
  • Length: 11"
  • Seat Channel Opening - Top: 10"
  • Seat Channel Opening - Bottom: 14"


  • 45 Liters, 2750 cu.in.

Great bag Great luggage bag for trips and camping. Very well made and comes with the attachments to secure to your bike - no need for bungie cords. Love it! Only wish I'd gotten one sooner. July 14, 2014
Worth the money This is a great device, quite large and easy to put on and take off. my only two issues is that it has buckles for a shoulder strap but doesn't actually come with a shoulder strap and for the price it would have been good if it was actually waterproof. I am station in the UK and rain is def the norm here. May 24, 2014
Awesome! I bought this bag hoping it would fit on my FXDF and with a little adjusting it did! I am convinced that the bag will fit on most bikes due to the adjustment straps for fitting the bag are very long and are all highly adjustable to ensure a snug fit. The bag itself is well crafted and went well on a recent 1800km trip... Just a shame its not completely waterproof. I ended up wrapping a rain jacket around the bag as a makeshift rain cover. I will defiantly be using this bag all the time now, beats wearing a backpack!! September 23, 2013
Awesome bag This bag worked great. Took it on a 4 day mountain ride and strapped it to my KLR with a KLR brand tail bag and even with Wolfman dry saddle bags (fit like a back rest when full). Although it doesn't seem to be meant to fit with all of this other gear it fit well (I was worried because I couldn't find any other reviews talking about this mounting option). Durable and got very dirty but cleaned up easily and back to new. August 20, 2013
Great bag!!! great price!!! I bought this for an upcoming bike tour across the country this summer. So far I have used it a few times going camping. This bag is amazing. I love the thing. Fits all my camping gear inside including my clothes and other useless items. The bag is lined on the inside which keeps stuff dry for the most part. I haven't been caught in a downpour yet but I think it would keep most stuff dry. I really wish however they gave you a free rain cover to go with it and also a few more small pockets on the outside. and a shoulder strap would be cool too. It has a ton of straps though so don't get too confused trying to insall it. May take a minute but then its a breeze. June 13, 2013
Good quality Bought this bag two weeks ago and tested it on my Scrambler last weekend. It's a good bag for an overnight trip, held lot's and fixed to my bike ok if a little fiddley at first. It's the sort of bag that needs to be filled to make the shape sturdy. If you are not going to fill it at least on the scrambler I would probably look elsewhere otherwise great product. May 7, 2013
Great bag, great design i needed a large bag that would easily swap between bikes (triumph thruxton, bmw f800r) and did not need any type of rack or hardware installed. fits both bikes perfectly, really quick on/off. can be a bit floppy if you are going somewhere and it is empty, definitely designed to be packed full. still very happy with this bag, but for the price it would have been nice if they threw in the optional rain cover. April 22, 2013
Great Bag at a Great Value This soft bag fit my 990R Adventure perfectly. The cut / shape of the bag straddled the seat so well it seemed to be made specifically for the bike. It will be great for additional gear on an extended trip. It is cavernous yet contents are easy to find once inside due to the large zippered opening. If your an Adventure rider wanting to keep things light by using soft luggage, this is a great bag at a great value. WJR February 4, 2013

Fernando P: Dear Kevin,

First of all I need to apologize for my terrible English. I have the Beta plus rear bag and it fits great in my BMW R1200R. Enough room for a short or medium trip it holds perfectly in the rear seat of my bike. At first I was concerned if it would hold still while riding in the not so smooth roads here in Brazil but it did.
you choose to buy this item I think you will not be disappointed.

I can send photos if you want of the bag being used in real life conditions.

All the best,

larry b: Hi. I recently purchased the Beta bag and have used it for two tours.The bag works well and will hold more than one would think. It needs to be fully loaded to be effective.I found the strapping system somewhat awkward and had to utilize a couple of heavy duty tie wraps to attach the bag and straps to my naked 79 GL 1000. I would think a more modern bike would negate this somewhat. The bag is well made and stable on the bike once secured. It is not a quick on/off bag. Hope this helps with your decision sorry about the tardiness in replying. Sep 10, 2013

Andrew P: I have no experience with the expedition but the beta rear will attach fine. They seem to work better when packed full to if she isn't carrying a lot of gear maybe get the smaller one. If the rear signals are on the stock fender then they should not be obstructed. Aug 27, 2013

kenneth s: The beta plus is a great bag. It mounts easily with a strap that goes under the rear fender and two more that attach to the passenger peg mounts. It has tons of room. Its not waterproof but is highly water resistant.

Tony M: I have the beta bag....gret quality and enough tie downs to secure it to most bikes. It's one of those bags that needs to be filled to hold shape but once packed its great. I recommend it. Aug 28, 2013

Andrew L: Hi Kevin, I believe the bag would fit the bandit great. I had a 1200 Bandit and it would have fit no problem, the bag is a large bag and sort of flops around when unloaded. you can mount it a bunch of different ways if you buy about 5 bucks worth of straps thats what I did and am super happy with it. Get the straps at a local outdoor store. When loaded sits great and looks great, if your planning on a longer trip remember to get the water proof cover for it. Wolfman's luggage only down fall is that they don't include a rain cover for the product's that aren't completely water proof, other then that its a great product and I would recommend it. Mine is currently on a Yamaha Super Tenere

Hope this helped

A shopper asked: If i were to leave this bag on my bike while im away from it, can i somehow lock it to my bike/lock it closed? i would assume a regular padlock or something would be ok on the zipper, but what about locking it to my bike somehow? Mar 19, 2014

Gene L: Don't know of a way to secure it to my bike short of wrapping a cable lock around the bag and the seat strap The bag is large enough that I think it would discourage a potiential thief from trying to take the whole thing. maybe a fine piece of fish line attached to the bag and the bike that actives a loud sonic alarm in the bag if some one removes it?I Mar 19, 2014
Reply to Gene Good answer? Yes (0) No (0)
Jeffrey S: Short answer is no!
All a thief would have to do is cut the straps that secure the bag to the bike and it's gone in seconds. But that is also an advantage as the rider can remove the bag in less than a minute if he/she is worried about theft.
That being said,, It is a great soft bag. Well made and It holds a lot of gear.

Dennis W: It can be done but if some one wants to get in all it takes is a simple pocket knife. Hate to be pessimistic but thieves will look for the path of least resistance and a soft bag is no match. Love the bag, but it is not really secure. Good luck. Mar 19, 2014

Joseph A asked: I will be doing a 10 day road trip around Nova Scotia (no camping) on my 2010 Triumph Bonneville. This seems like an excellent alternative to getting hard side saddles installed (I already have a rear top box installed). Wanted to know if I should go with the Beta Plus model, or the mini Beta Plus? I know the measurements are different for each bag as to where they lay across the rear saddle of the bike. Any advice would be most appreciated. Thanks :-) Feb 20, 2014

Brett V: For a 10 day trip go ahead and get the Beta for the volume. I own it and it is well made and attaches securely to the bike (Triumph Tiger 1200). Be sure to include a rain liner or cover in the purchase. Over a 10 day ride you will surely get into some foul weather. If I'm not mistaken the new model comes with a waterproof liner. Hope this helps. Have a great trip. Feb 20, 2014

David D: I bought two of these and my son and I like them very much. We took some day rides and weekend rides last year and they seem to work best fully loaded. They are built well. Also bought the rain cover, just in case. We plan on taking them on our CDR ride this July. I just bought the Wolfman Expedition saddle bags and have not used them yet but they also look well built. Been happy with both purchases. The Beta plus was our choice.
Feb 20, 2014
Reply to David Good answer? Yes (0) No (0)
Joseph A: Thanks for the response, David. I'm leaning towards the choice you made (Beta Plus), since the channel dimensions on that one seem a better "fit" to the dimensions on the rear seat of my Bonnie. Feb 20, 2014
Matthew S: I would go with the larger bag. if you don't use the top box at some point this bag has plenty of room for everything. It straps on/off quickly once you adjust it for your bike. it might hang down about five inches on the sides, check that you have the clearance. have fun on your ride! Feb 21, 2014

Joseph A: Thanks for the response, Oliver. I think the Beta Plus is what I'm going to end up purchasing (along with the rain cover). Feb 20, 2014
A shopper asked: I have a 2013 Vrod muscle. Will this bag be ok on the rear fender without scratching the paint? I"m trying to find a storage bag that can also be used as a back rest for rear passenger. Nov 14, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Troy S: I cannot respond to your question concerning a Vrod Muscle. I mounted my bag, padded with a folded bath towel, across the rear fender of a 2001 Honda ST1100. I then rode the bike from N.C. to Colorado, Wyoming, Montana, South Dakota, back through Colorado to New Mexico and Home. We experienced nine straight days of rain, out maneuvered three tornados (Nebraska, Oklahoma and Texas), experienced high cross winds across New Mexico and an additional two days of rain returning out of Tennessee into mid-North Carolina. Our 14 day trip was extended to 17 days due to inclimate weather. The bag was stuffed with a waterproof liner and all the contents were off-loaded and re-packed in a motel each night. We had no problems with leaks with the waterproof bag liner. The Wolfman Beta Plus Rear Bag performed flawlessly. I would be hesitant to strap the bag directly to the rear fender without some type of padding. Sand from the roads out West (particularly in Wyoming, South Dakota, and the desert areas of New Mexico) can work their way between you bag and fender. Without some type of padding I think that you will experience the effects of sanding between the surfaces. I hope this information helps in protecting you bike and your gear. I don't think you can go wrong with the purchase of a "Beta Plus" but also add a bag liner. Cheers, Troy Shirley Nov 28, 2013

Kimberly B: I've never tried to attach a bag to a fender, so I can't speak to the attachment points stability of it. I also don't know much about the configuration of the back of an HD. I can say this though . . . Across the back seat of my Triumph Scrambler, it serves as an excellent backrest when full. When empty, the sides droop down and come close to contacting my high exhaust pipe. I have to use the side-cinching straps to carefully secure the sides of the bag.

My Wolfman tank bag has the same kind of rubber contact surface as this tail bag; and while it hasn't scratched the paint on my tank, the chrome gas cap has seen better days. Like anything, I think it mostly comes down to how clean you keep the surfaces that are in contact.

A S: Thanks Kimberly, I appreciate your input. I think it will work well for travels and supporting my girls back. Nov 14, 2013
EDWIN Z: The bottom of this bag has a rubberized texturized surface which might damage the paint on your fender. Honestly, I don't think this bag was meant to be used on a fender---it is way too big and has lots of straps and may pose a hazard of getting caught in your rear wheel thus causing a crash. I would use this bag only on a luggage rack or a passenger seat---definitely not on a rear fender. Nov 25, 2013
Reply to EDWIN Good answer? Yes (0) No (0)
Matthew S: I believe this bag would not work as a backrest for a passenger. When full it might be eight inches tall where the passengers lower back would touch. Also, the bag is fairly long front-to-back when filled and from the looks of pictures I would guess that if you put this bag on your Vrod it would cover the passenger seat and your tail fender. Hope this helps.

A shopper asked: Hello, my bike is ducati monster 696 2011.
I don't know is this bag fit on my bike? Because of my bike's exhaust is pretty high (near the seat). However, I saw someone use mini one, and it is fit.
I wonder I can buy the plus one, because I need to put a spare oil tank inside the bag.
Thank you for your help!

Anthony M: The over hang is about 5", so you'd need your exhaust to be at least 7" lower than the top of the seat where the bag will be. That would leave you with 2" between the bottom of the bag and top of exhaust. Not sure if that is enough but I personally wouldn't have it any closer than 2". Jun 2, 2014

Gene L: My bike is a Yamaha Warrior with low pipes. The bags hang down about 8 inches from. the top of my rear seat. You maybe able to position them forward for more exhaust clearanc. they make a great back rest for a long ride

Robert K: I roll around on a Honda CB500F and the smaller bag when filled is quite large. I would suggest getting whichever bag you needed to fit your needs, but the smaller is my main bag for a minimalist cross country (USA) trip. Looking at your bike I would agree with Brett V in that the smaller size is probably the better choice. May 18, 2014

Brett V: I had to look up your bike in the Guzzi web page. I have the Beta Plus, it is a very large bag. To fit the bike size the G7 is I would opt for the smaller size. May 13, 2014
