Those bladder things do look like the answer to occasionally carrying extra fuel and 7 litres is a handy size, but they certainly don't look like $100's worth to me. From the way they look in the photographs I can imagine Chinese factories knocking them out for under $2 each.

Are they better made than they look to justify the price?

They're pretty rugged and like you say perfect for occasional range without having to carry all that air. I can't find anything else that's this convenient.

The US ones are USD109 plus tax/shipping, the SA ones were GBP68 plus tax and shipping. The days of super cheap chinese stuff is past.

I am in China now, if any one wants me to find the suppliers here, then thats no problem.

Like said before, they probably about £20 or $30 at most here.

Vette,

It would be useful if you could find out how much they would cost and the quantity they would need for an order.

Update:
 

I have another spare 7Ltr one. My friend doesn't need both of his now so I can offer it to someone else. Any interest?
I can get it in the post tomorrow morning if you pm me.

Be interesting to see if these bladders can meet the performance tests required for carrying dangerous goods - look for a little circle with UN inside and some numbers under it to see if has undergone the testing. I doubt any bladder will survive the drop test - which is about 1% of the forces you'd get in 50kph accident, let alone some of the venting/expansion requirements.

There are plenty of bladders around for diesel (which is not a dangerous good) because of its higher flash point (+63C) than petrol (-24C).

The bladders that were being sold by an Aussie company I could never find any details about their approval for use as petrol bladders.

I know the UN approval process all seems to be over the top for just 7litres of petrol, but the performance tests have been developed over the years - mainly after people have sufferd at the hands of putting petrol in containers that were not designed for it.

seriously
 

A 7ltr bladder is unlikely to be part of your day-to-day fuel strategy. These rubberised bladders are seriously tough and a massive step up from 1.5ltr coca-cola bottles (if not in price!). The manufacturer rates them (burstpressure:0.48 MPa, drop-height: 4.5m) and they do exactly what they're supposed to. People need to know, and are more than sufficiently reminded here, that these aren't legal in the UK for carrying fuel but this is a travelling site and needs must.

I'll make sure I bear that in mind next time I use a zip-lock sandwhich bag to transfer fuel between bikes.

C'mon, reality check please. We are talking about a standby way of adding some short term extra fuel capacity. As said, beats a pop bottle or three.

I carried fuel in pop bottles trying to cover a big stretch of patagonia. Routa 40...

I dropped the bike in the gravel and the bottles split open, draining all of my fuel into the dry earth and over my luggage and seat. They didn't even take the brunt of any force.

That f**ked up my plan big time and led to a nightmarish day of stress and worry. I WON'T ever use pop bottles again.

I've got a 10L rhino can on the back of my DRZ now. Cost about £10, although the space it takes up is permanent. I'd rather have a small back box there. :thumbdown:

My worry about these bladders is if the bike lands on them, or they're "Squished", how will the seams stand up ??

You will have to rely on KNOWING when you need the extra fuel. I doubt you'd want to carry them full all the time just in case you need it. Not a problem with a jerry.

Also, they look a nightmare to carry when full.. A cargo net would probably help a lot though.

Plus, I don't think I could part with that much cash for a rubber bag !


It's too late for me to swap my jerry for a bladder but i'm really looking forward to some more road testing from you guys !:thumbup1:

Exactly. I thought we were supposed to be a bit more adventurous that than.

It's a good point. What I think you'll find is that the bladders will stand up to being squished better than most things other than a metal jerry. The weakness of a bag is from sharp objects but I've yet to rip the drybag on my rear rack. You do have to think about where to attach the bladder when you do want to fill it but for small bikes it's nice not needing a flat surface to put a jerry can on (I have no room left on my wr).

You're talking more about planning here. The world isn't the barren wasteland it once was. How ever much fuel you're carrying it would be wise to factor in a safety margin on the relatively 'known' distance you're attempting to travel. That is just sensible. Jerrys or bladders just give you a greater range to apply that safety margin to.

And its always a group unusual events when accidents occur, the fuel container issue is just a part of risk reduction for any trip - just like wearing boots instead of thongs. If you want 750kms fuel range, buy a tank or bike that gives you the range.

About 95% of accidents involve another party (5% single vehicle accidents), so whilst you maybe prepared to accept the risk of injury to yourself - maybe other people would take a dimmer view of being sprayed with petrol, especially in remote areas of third world countries where medical help may not be available to them - whilst you get an air ambulance home.

RogerM, I take onboard the aspect of risk reduction. Using road networks for prolonged periods of time on a trip is inherently risky and much can be done to minimise it. The impact of a risk does not affect its probability and in a case where you're carrying 7Ltrs of fuel on an occasional basis your likelihood of 'spraying' anyone other than yourself when you fill it up is, at best, slight. That's before we get onto not needing 750km ranges all the time or wanting to spend hundreds on a new, large tank - if they even make one for your bike in the first place.

We'll just have to agree to disagree - I'll buy you a pint with the money I save on a bigger tank if you agree to pour it on me if my bladder catches fire :thumbup1:
