    I'm all ears for the one piece tank / subframe combination like the 690's :)

    I've carried a 20 litre can of gas on the back on more than a few occassions now and honestly I couldnt even tell it was there. That was also with a weeks worth of gear on the bike.

    :dunno

    Plus I think half the allure of this type of setup (rally tanks) is the "rally look". Sure it easier to just use plastic bags or coke bottle's but that kind of isn't the point. Just an opinion :D

    I dont think you can accuse the 950/990Adv of having a light front end... (in its natural, unloaded state)
    How much gear are you carrying?
    I cant say I have carried heavy loads on mine, but I would have thought the adverse dynamics are as much to do with how high the weight is as how far back it is?

    On the tar or hard packed dirt I totally agree but surely you didnt buy a KTM to do what a BMW can do:rofl

    If you havent ridden soft sand with weight on the back you may not know what Im talking about.

    This little sandy track to a camping spot beside a river off the main road was a real challenge. On an unladen bike it would have been a piece of cake.

    Those two bags on the back would be lucky to weigh 15kg.

    It would only be common sense to think what ever weight you pack behind the rider needs to needs to be balanced out with similar weight in front of the rider if your looking for the best handling the bike can offer.

    I love the look of the Rallye bikes dont get me wrong but Im just looking at the practical side of things.

    911 - Ive done similar trips on my 950 with the gobis and stock pipes. By shedding the cans and gobis, going to the GPR and soft bags ive saved just under 20kg that was dead weight. The tank will be carried forward and low and being linked - centralised which shouldnt have an adverse affect on handling. As for how much you take "camping" well thats a self inflicted tax that Ive got down to about 12 kg total.
    What Im saying is the tank will carry fuel when needed and when distances dont require it - they'll be empty. I'll be keeping the rear luggage plate and handles - maybe a semi custom rack to keep the bags out but the tank is a better bet than jerrys or other slung on up high.
    Might even get me a set of those safari's and have near 70 lt of fuel for - well I dont know what but it sure would be a long way between fills.

    I've ridden soft sand with weight on the back and still have no clue what you are talking about. :dunno

    I've got no idea what your talking about but i've ridden soft sand.

    Just about to fit Neduro tank,2 into 1 etc.
    Following this thread ....

    Was thinking of attaching 5l a side on front crash bars/passenger footpegs.

    Pete, finish this as a single tank and I'll buy one. If possible leave enough room for a battery as mine has been in that location for two years. 4kg off front of the bike. Fuel mass centralised behind engine is good. Being able to take weight off front or rear as required is good. Built rally style single last year so just need to redo from collector to suit your tank. Nice power change and sound with K1200 Acra. Engine seems smoother. Loaded panniers create a pendulum effect, heavy weight better on rear of seat where a pillion would be. Also have camping gear to about 12kg. Have 60k on bike since new, mmm not need GF :lol3 Tony.

    Different bike but i rode a XR600 with a 23l tank plus a 10kg tail pack and it was practically unrideable, removed the tail pack and it was like riding an enduro bike in comparison, loads of fun very easy to chuck about.

    Can't say specifically for the 950 but you will reach a point where weight over the rear if it's high and far back (i.e. on the luggage carrier) will cause problems particularly if the front tanks are nearly empty as there's less weight on the front.

    I also rode an Aprilia Pegaso in soft sand with luggage and 10l extra fuel but the rear luggage was mounted on the rear footpegs (i.e. as low and as far forward as i could get it) and the fuel was carried either side of the engine with the bottom of the cans near the bashplate and you could hardly notice the extra weight and playing in the sand was just that.

    Dead right...... of course with rear tanks the weight is carried low.

    With rear tanks (22Lt) my procedure after filling would be to travel 100km with the rear closed. To lower the front levels to prevent syphoning, then run all 4 tanks at the same time till empty. The bike has a beautiful balanced feel to it. I do this on the road as well.

    I also subscribe to the travel light line of thought. Very light!

    This bike was born with 4 tanks to be ridden on the desert sands

    Wow - that is one heavy battery. Weighed my old one for interest and its just under 3kg. Im going the single tank route (progress is about 2 weeks off - CF 690 rallye bashie copy mould almost finished - part fits brilliantly) but with the mould being a female its easy enough to make an insert that will allow room for a battery if thats your thing. Any downside to having your battery there - up under the seat?:ear

    hmm it has been a while since I weighed it, and then it was on an old set of bathroom scales, maybe I'm lighter too.. The battery under the seat is fine, I mounted the start relay on the back of the airbox and only had to extend two wires from the regulator. Everything else reached. Very easy to jump start my bike or another. It was under the seat on the 950Rally and race bikes or cars dont place things without due reason. From what I've read, part of the handling gained on the 690rally over the 660rally, with regards rear end swapping side to side was the single tank allowing fuel weight into the centre. Alfie Cox called the 660 the 1 2 3 bike. Rear steps out 1 way then the other, then you get off... (watch old Dakar footage) bit like loaded panniers. Tony.

    Hhhmmmm - might try my battery there 1st to see if I can feel any difference before I decide on the final product. :dunno Ive also noticed in the "barbasma" pics the oil tank is under the seat as well - leaving one huge radiator up front and the oil cooler hanging just above it. As you said they dont spend big $$$$ putting things in places for no reason. If you get a chance look at the 690 rallye - so different to any road based "adv" bike that Ive seen. A place for everything and everything in its place.

    Yes the 690 is a very well packaged bike. Its obvious it was designed as a rally bike from the very beginning whereas the 660 kinda evolved throughout the years. Funny, just before this thread started I purchased a sheet of 3mm Alu to build an oil tank, as well as worked all of my AN fittings out. Your tank would provide a better solution. I'd also considered a tank like yours but in Alu. Looked at the AfricanQueens too but mixed reviews regarding the quality. The CF bash plate sounds promising too but the last bit of TIG work on my Alu one will be ready to pick up tomorrow. Should have procrastinated a little longer before starting it. I've changed my rear number plate holder for one from a '99Rally (which is '93EXC). Easy mod, looks right, fits well, small light but is really bright and has a reflector. KTM like using bits from the parts bin. Looks a million times better than the stock POS. Tony.

    Have a Photobucket account and can see an easy way to attach photos to facebook, twitter etc but not other websites. I'll look again.
