I was looking for space & I think these are the biggest bags I saw. They also had good reviews. Wish there had been a photo showing them open & the interior features, but obviously not a deal breaker.

My old bags were worn and falling apart
Heather T on Sep 1, 2014
I liked the reviews and I am going to try them on a four days trip in July.

They look adequate for non daily use.
Reza E on Apr 20, 2014
I'm replacing a set of the same that were damaged in a crash. These work well on my Triumph Bonneville with aftermarket Predator exhaust. I tried some other saddlebags that just didn't fit the bike as well as these. Also, these have a ton of storage space compared to most others.
Brandon R on Jan 26, 2014
Good reviews, good price and appears to be the best fit/choice for my cycle
Michael W on Jan 7, 2014
Mainly for the size- biggest soft saddlebags that I could find. You can easily fit a full size helmet inside each bag and still have space to carry more things! It could do with more integrated straps esp up front to hook up to the passenger pegs and a wide strap on which passenger can sit if the straps go over the seat.

Anyone have these on a Triumph Bonniville??
A C on Feb 10, 2016
BEST ANSWER: I put these on my 2014 Bonneville t-100 and they look/work great. I've taken them halfway across the country and also to/from the grocery store. Very easy to use. No issues. Lots of room.
Would this work on a dyna super glide with the detachable side rail mounts and turn signal relocation kit?
Justin J G on Jun 20, 2016
BEST ANSWER: Yes with easy brackets!!
Will they fit a 2007 Suzuki V-Strom 650 without any modifications?
A shopper on Feb 18, 2014
BEST ANSWER: I put these bags on a 2013 Kawasaki Versys. They basically attach via two wide straps sewn into each bag, which then secure to each other with Velcro that is sewn into each strap. You can then anchor each bag via 4 (2 each bag) plastic hooks on the backside of the bags to some part of your frame with budgies or cable ties. The exhaust system on the Versys runs along the bottom side of the frame, so heat against the bag wasn't a concern for me; but on a V-Strom, it seem like the right-side bag would reset right against your exhaust? That could be a problem I'd think if that area gets hot at all? Hope that info helps you out.
Will these fit OK on a Yamaha FZ6R? I have a separated passenger seat
A shopper on Aug 22, 2013
BEST ANSWER: I think they will work.

I used them with an S1000RR BMW also with seperated seat; ran the back strap under the passenger "seat" and the front one simply laid directly behind the driver seat. I also used a non-slip pad to ensure the straps didnt rubb paint and ran a bungie between the bags under the rear fender to keep any flopping in the wind to a minimum. Rode from LA to Monterey and back (very swiftly at times) and didnt have a problem.

Only "complaint" I have with them is they arent top opening; access to main storage compartments requires losening the buckled straps and opening the zipper carefully to keep your stuff from falling out. I think I would have liked top opening models better.
Is 2 to 3 inches of overlap on the wide velcro seat straps enough to hold loaded bags together once mounted on the bike? I just bought these for my new R1200GSW with Givi pannier racks, and the bags sure look like they could use longer straps once positioned on the bike properly. No instructions with the bags unfortunately to advise how much overlap is required to keep the bags together once loaded.
John W on Sep 12, 2014
BEST ANSWER: You would have to use your judgement on that based on how much stuff you are carrying in there. The velcro is really strong but I have always had at least 5 inches of overlap. This is on a FZ09 so the seat and bike, in general, is narrower and I can have the straps on top of the seat. I have seen some others who have used these on their GS without any issues...check on the r1200gs dot info forums. The trick is to use it under the seat I think.
I have a 2012 Triumph Thruxton and want to know if this will fit the bike and, if so, do I need any type of extra bracket for the bags?
A shopper on May 28, 2014
BEST ANSWER: I use them on an sv1000s, and the bags sit high away from the wheel and caliper chain area, so I didnt need brakets. You bike is lower so I would recommend it, only because these bags fit my Harley softail but I use a bracket to keep them away from the wheels. The bags can carry more than they look I packed more stuff in them than on my harley saddlebags.
Will these work on a 2013 Shadow Spirit 750c2 with the Honda saddlebag mounts?
Eric F on Sep 14, 2014
BEST ANSWER: I used them on my Ninja 650 ABS and they worked great. Don't be too worried if they have a little bounce to them. I suggest using the passenger pegs to create a little barrier so they cannot hit the rear tire.
Will these saddlebags work on a Kawasaki ZX 14R? I'm looking for ones that will.
A S on May 12, 2014
BEST ANSWER: I bought these bags for my 650 Vstrom. I already have GIVI racks. There is no obvious way to mount these solidly. However, I saw a universal pannier mounting system in the Touratech catalog. I copied their system and added a piece of 1/4" plywood backing inside the bags for support. I have used them twice on long rides so far and they work fine.
Can the zippers lock?
A shopper on Sep 20, 2013
BEST ANSWER: There is no provision to lock the zippers, however if you would obtain just the right sized lock with a small diameter hasp, it should be possible to latch together the 2 zipper actuators so that both would have to move together and the main compartment could not be accessed.

Meanwhile, if someone wanted to grab and run with your gear it would be easy unless you had a bicycle cable lock through the "D" rings and part of your frame.

I also use these bags when flying on trips, they are a handy size and hold a lot.

can be installed in a BMW g 650 gs
A shopper on Jan 27, 2013
BEST ANSWER: These saddlebags don't really call for a specific fit like other cases do. Since they just straddle the saddle (rhyme!), there's a wide range of bikes that they would fit on. The only thing to keep an eye out for would be where your exhaust is located. From what I know your exhaust cans fit nicely underneath the rear seat. These bags are heat resistant, but only to a point. Too much contact with hot pipes and WOOSH, your bags are on fire. Or probably something less dramatic, but still traumatic (another rhyme)!
