Top box failure

While out on a ride along some nice country roads last weekend, with my wife on the back, hit a sharp bump and felt something go, thought it was a tyre. Turns out the top box (Givi) somehow came loose and fell off. Fortunately the fellow rider who we were riding with was in front of us not behind, neither was there a car behind us.

The box while a bit battered was fine, just lying there in the middle of the road. Nothing broke on it so I can't understand how it came loose. I can shake the hell out of it and can't budge it but I'm guessing that maybe the bump in the road just caught it at the right angle to dislodge it. Good thing my wife wasn't leaning back on it, took her a while before she realised what had happened.

It lives on the bike as I ride in to work every day, so it stores my helmet and wet weather gear if I need it. Admittedly it would cause havoc if it fell off going over the Sydney harbour bridge in peak hour traffic. Need to think about a secondary fastening system as a backup.

Am I understanding correctly; the Givi box came off of its mount? If so, you may need to rebuild the internals of the latch. I had the same thing happen to the Givi side bag that held my toolkit and some other stuff when I hit a giant pothole on the Williamsburg Bridge at 100MPH one morning.

Cheers,

What mounting system are you using?

I lost a GIVI V46 a few years ago when some bolts on the SW Motech bracket came loose.

I'm now using the GIVI mounting system but I keep a close eye on it.

...always remember the lubrication...

My shiny red 675 morphed into a shiny (soon to be muddy) Scrambler!
(The Scrambler became flying lessons...)

Guys - the Givi topcase rack on the Sprint ST puts the case right over the heat of the beautiful but extremely hot exhaust. Prolonged exposure to the heat when cooling (especially on an every day commuter) is hell for the plastic internals.

I've had to replace my Monokey topcase because the plastic internals locking the case onto the rack just melted. While the case would stay locked closed, you could, AT ANY TIME, push the red release button to take the case off the rack, even when the case was locked with key in locked position.

Maybe yours just melted a bit more, allowing for it to detach?

My solution was to buy a big adhesive sheet of heat reflective material and laboriously cut it to fit the bottom of my replacement E52 and so far, no problems.

My guess is it's the heat.

Thanks everyone for your experiences. The funny thing is that nothing appears to be wrong with it. It's on the standard Givi rack which is rock solid. The case itself is undamaged, no signs of melting or any broken bits. Tested the lock too and I can't push the button in when in a locked position.

Will take a more careful look again this weekend to see what it might be. I've grabbed is and shaken it vigorously a few times since then and it doesnt' move. I did think that maybe I bumped the red button when I had the box unlocked but I doubt that as it would have come off a lot sooner had it been unlocked. Maybe its just a combination of a few things, heat off the exhaust at the same time as a bump at just the right time. I'm guessing that the heat could well change the rigidity of the plastic without actually showing any signs of melting. Next time I am out riding I will stop and feel the bottom of the box to see how hot its getting.

I've read other forums where Givi top boxes have come off. Seems maybe the latch just wears out enough to let go is what I recall one person saying.

I know on my Bestem Givi clone, I can hear the latch click, but a few times it was not completely seated and I could lift the box right bac off though supposedly locked and latched. I learned to push down harder to get a second, more definite "click."

I'd call a Givi distributor and ask them what the problem is.

I always push the button in when I attach the Givi box to the mount, thinking that it will increase the longevity of the mechanism because there is less force used on the catch mechanism when it is secured this way. I do pull upward on it to be assured it is securely fastened before flight, though.

I'd NEVER trust a top box/panniers without at least one good bungees cord permanently attached for back up.........

It's not a question of will it

it's just a question of when will it..........
