Givi E450 Simply Monolock Top Case Videos

Givi E450 Simply Monolock Top Case

The E450 is one of the most spacious cases in the Monolock range (with 45 liters maximum capacity). Equipped with a wide reflector, it is characterized by its modern design and by its proven automatic opening/detaching system. The Monolock system only requires you to turn the key and press the red button to open or remove the top case from the the bike. 

The E450 is the ideal midsize top case, as it can hold one large full face helmet (or two small full face helmets) or 45 liters of other gear.

  • Holds 2 helmets
  • Dimensions: 22" L x 16.7" W x 12.7" H
  • Capacity: 45 liters
  • Max load: 6.6 lbs
  • Empty weight: 8.47 lbs

Note: All Monolock top cases include a universal plate.

Givi E450 Simply Monolock Top Case 4.5 5 13 13
Great bang for the buck Based on some of the other reviews, I was somewhat hesitant to buy one of these topcases for my KLR650 - I thought maybe I should spring for the fancier, more expensive monokey cases. But since Revzilla has such an awesome return policy ($7.50 to ship back) I figured I'd give it a try. Not disappointed. Mounting system is brilliant, really easy to install. Huge case, well detailed. Locking system seems quite robust. If I had to complain about something it would be the lack of straps or even tie down anchors inside the case. But overall I've been really happy with it. September 14, 2015
Priced cheap and built that way too. This is a cheaply made top case. Everything on it works OK, but it is thin-walled to the point that the top doesn't mesh with the bottom without pushing it into shape. The cautions say not to drive over 120 kph with it. That's about 70 mph. I gave it a weak recommend simply because if you want to go cheap, which I did, it will work. July 7, 2015
Great product Givi makes a great product. Easy to install and good quality. I would recommend this to everyone. June 15, 2015
Flimsy and hard to install This top bag is pretty, no doubt. Unfortunately, Givi's definition of "universal" needs some work. The only way I could mount the base plate on my R1100's tail rack is to position it so far forward that the only pillion that could possibly fit between me and the case is a little kid; any further back and the release button interferes with the rack. Repeatedly installing and testing and relocating the base causes the nylock nuts to strip out. Otherwise, if I want to mount it in a more reasonable position, I have to perform major surgery on the rack with a dremel. The case itself feels flimsy (Givi warns that max speed with it installed is 120kph, or about 70mph), and latching the lid is nothing like "just press to close" as described in the manual. It took me a good 30 minutes of fiddling and swearing before I figured it out. I probably should have spent the extra $300 for a Monokey case and dedicated base plate, but this case will do for now.

Easy to use, functional Wanted a moderately sized case, big enough for at least one helmet but not too large for bike. Was easy to install and does the job, also good backrest for passenger. September 15, 2014
Top notch! Excellent product especially considering the price and that it comes with the mounting plate and hardware that are sometimes optional. (Speaking of options, it can also be had with a brake light kit and a passenger backrest.) The trunk is easily removed with the simple turn of a key and then used as luggage which is incredibly useful when you don't need it on the bike such as when off-roading. I have a 2013 Honda CRF250L with a ManRacks rear rack. The hardware didn't quite fit the design of that rack so I bought two pieces of steel at the local hardware store and drilled the appropriate holes in them. Installation took less than an hour (including the trip to the store) so I really can't complain. As far as durability is concerned, I've only had this for two weeks so I really can't say yet.

great and stable case (lightweight) can only say good things about this top case. Easy to mount on my Tiger Triumph and does the job of holding my bag and two full face helmets without the Bluetooth navi. Just installed the intercom systems and will have to see if the helmets still fit. I have some trouble at times opening the secured lid as one has to hold down the lid slightly and then disengage the hook that keeps it from accidentally opening by itself but otherwise a great case for the money! Ride safely! February 3, 2014
Great Product, plenty of space Fast shipping, the product is high quality and fits my Piaggio BV500 perfectly. January 13, 2014

Shawn V: Returned this case, it was not a good fit on my bike. Nov 27, 2015
Craig H: I already have a top case, but it's now too small for my needs, and Givi have always been known for quality, and this one has 45L, as opposed to my current one of 27L, so this fits the bill! Nov 17, 2015
Mark M: price point and size Nov 8, 2015
Dave G: Had one of these on a previous bike and it was great for normal use. Decided to buy another one for current bike. Givi makes a quality product and not expensive. Sep 30, 2015

Daniel M: This case seemed like a good choice with ample storage space and GIVI workmanship. Jun 23, 2015
Thomas L: price and size and its not a Shad, owned Shad in the past and not pleased, I hope Givi is better quality Jun 3, 2015
Coinneach F: Givi quality, less expensive than Monokey, doesn't require bike-specific mounting kit. May 28, 2015

Adam S: Greetings. I mounted this top case just prior to leaving on a 3200 mile trip out East last fall. In it were my DSLR camera, iPad and other items. The mounting was secure; never hesitated putting anything valuable in it for whatever the distance or speed. My only gripe about the unit is the plastic it is constructed of seems a bit on the thin and flimsy side, considering the "name" that Givi has. The lid can be flexed quite a bit, to the point where it comes close to not lining up perfectly with the latch at times. This seems to either be in the hinges or the lid itself....maybe both. However, nothing negative having to do with the attachment of the case to the bike itself, which I feel is totally rock solid. I just feel the case as a whole is a tad on the cheap side. And once the lid is latched, it's latched tight and very secure.
Good luck and safe travels.

Kurt L: In short, yes. If i were taking my laptop, i'd just make sure it was in a padded case with some stuff around it in the topbox so it wouldn't bang around too much. (Lots of potholes here in Pittsburgh...)
I had my doubts at first due to the recommended weight limit... but it holds a lot more weight than that. I bought it for commuting, and throw my workbag in there. i've even carried a case of beer in there for a short trip. As long as you're not rock-hopping, it'll carry a lot of weight.
It's also water-tight, as far as I've experienced. I' only got caught in the rain a couple of times (and once in the snow), but everything inside stayed dry.
It's almost a must-have for me for commuting. I'd buy it again.

Josh R: I commute to work with this case and keep my laptop in my backpack in the case. I also keep spare gloves, tire patch kit, and other little stuff in there. I feel very comfortable with the case AFTER I replaced the mounting hardware with a 1" x 1/8" flat steel bar I cut and drilled to replace the hooks that came with it. I also picked up 6 thicker bolts to hold the steel in place. With the sturdier hardware I've easily put over 20 lbs in it without worry. May 8, 2014

Francisco M: Personally I think it would put the laptop in a backpack, and the other electronic.

This is because it hit against the sides of the top case.

It is of very good quality, so yes you could take it as well; I carry my iPad and camera in a backpack.

Remember that the specifications of the top case can explain that move at speed and not exceed it.

Frank M: Yes. This is a great case and well made, but light. I have tried many cases, including BMW and Ducati cases, and feel the Givi are better made, easier to install, and less expensive. I would also recommend the Blade tech 47 which does not look much larger than the Simply, but it holds 2 helmets and looks better. May 9, 2014

Ed U: I throw my tablet in the topcase all the time, and have carried the laptop(in its padded bag) in it with no problems. A standard dell laptop bag lays in there with not much space left over on the sides, so it won't slide around. May 9, 2014

Answer this · Send to friends Good question? Yes (0) No (0)
Kurt L: there's a mounting plate that either comes with it or you'd have to get separately (can't remember which). The mounting plate attaches to your rear rack, then the case attaches to the mounting plate.
you'll need some sort of rack on your bike; i have a givi rack.
couldn't see the 450 on revzilla, but the 470 says it includes a universal mounting plate.

Dominic C asked: I want to get a topcase for a honda pcx 150 scooter. Which would you recommend? If Mono lock should I buy the honda specific rack or would the universal one that comes with it be good enough?

Thanks for the help.

A shopper asked: What is the difference between the Monolock and the Monokey line? Apr 17, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
GEORGE W: According to the Givi web site (complete with typos): "The MonoKey series are actually the top of the line series with a more substantial mount, more features, and better quality construction. The MonoLock cases are generally smaller and lighter top case with a smaller mount and lock up.You should consider MonoLock cases for “light duty” applications. Monolock cases are single skinned and of lightweight construction so they are for perfect use on scooters and small mororcycle but they are not suitable for high speed use. May 4, 2015

A shopper asked: I have a suzuki sv1000s 2003, I'm looking for a top s case and mount/plate as well, would the Monolock Givi top case E450 with the universal mount work on my bike that's currently listed on your site or should i go for a different mount/plate? Apr 5, 2015

Mike P: This should work so long as you have some kind of rear luggage rack that's mounted to your bike. The Monolock mount plate has wide flanged bolts and washers that you screw on to secure the plate, and if I recall correctly when I installed my Monolock it was very easy to locate the plate on the rack where everything jived nicely.

I googled a few photos of the SV1000S rear rack and you should be OK. Worst-case scenario, there's always a return policy.
