    Hello all,
    I have a Burstner Aviano to which I have fitted a motorbike rack for my Yamaha 125. I also want to fit a 2-bicycle rack but not onto the camper itself or as an attachment extending from the motorbike rack.
    I like the racks that fit onto the towbar itself but with the m/bike in place, standard racks are too low and no good. I was thinking that some metal fabricator company could design and fit "extension legs" to the standard racks so that the bikes sit nicely above the motorbike. I can live with the inconvenience of reaching over the motorbike to get to the bikes but can anyone confirm that my idea could be achievable? I am not technical or practical in any way so perhaps my idea is too far fetched? Or Perhaps a fellow member could recommend a completely different approach?

    Many thanks

    wow you must have some substantial load limit on your back axle:Rofl1:

    another 30kg on the back of the van has more like a 40kg affect on the axle. add the motorbike, rack, bikes and rack extension and you're getting pretty heavy. don't forget as well the maximum downward load on a towbar is typically 100kg max

    however I'm sure you've done the calculations and weighed the van though, havent you?:Rofl1:

    If I were a betting man I'd say there was a good chance the rack and the bike put you over the limit, better not put too much petrol in bike tank! :Eeek:

    The aviano is plated at 4000kilos with 2400 on the rear axle. According to the (well respected) rack fitter i can take a motorbike up to 170 kilos without issue. My 125 weighs in at 125kgs. They also fitted the bike extension to the rack so they must have thought that this was also within the limits of my camper. (I have taken the extension off because it made it all too long for my liking.)

    have you thought about a front mounted bicycle rack .
    certainly in the states its common to put m,bikes across the front . i know a few that have done it here and abroad . its a good way of loading the front axle .
    i think your idea could be done but the stress on the tow bar and chassis is going to be high .

    Thanks. The front mount seems a little too "left-field" for someone like me. I have to rely on the info I received when i ordered the motorbike rack that it was well within my weight limit. I had purchased the camper on that assumption too, confirmed by the dealer!!
    I have an alko chassis and I am comfident that it will be okay. I will be taking the loaded camper over a weighbridge and see what transpires.
    Thanks again.

    are front towbars and additional brackets still legal in the uk? i havent seen front towbars advertised for quite a while now and thought the legislation for bullbars did for them?

    i would expect a motorbike rack manufacturer to have confidence in his product. however the towbar loading situation may well be different. Fiat and Alko suggest a maximum towbar loading or downforce of 100kg. I know which one I would trust, and its youre decision and risk. adding to the motorbike carrier would draw attention to your van and make you a target for inspection

    by the way I saw VOSA stopping motorhomes at Ashley Heath by Ringwood and taking them in for weighing recently. Just friendly advice that you make certain youre all legal and safe before it spoils your FUN:thumb:

    have been googling front towbars, and although still available for maneuvering trailers or boats, the manufacturers say detach them when on the road. interested to know how winch bumpers get past this for pedestrian safety puposes. mind you, towbars are now in the MOT so things may get more interesting:Wink:

    just about every landrover round here as a front tow hitch . many have winch bumpers . cant say as i have ever heard of a problem . still buy bull bars . dont think they did get outlawed .

    If the vehicle is used for work or off road - then you can have winch bumpers etc. It is aimed at chelsea tractor type users that want them for show as opposed to use.

    I agree about the downward forces on towbars, the heavy duty ones will withstand 146kg downward force - but you have to remember than many towbars fitted to motorhomes are either fabricated, or have not yet been tested, so nothing is guaranteed.

    You also have to look at how it is attached, length from fitting point to ball and also the axle weights as the lever action will lower the figure.

    Are you sure you have an Alko chassis. I have a Aviano and it has the standard Fiat chassis with extensions. I thought only the Eligance had the Alko Chassis.
    I have weighed mine with full water, full fuel, 3 push bikes, 3 people and all that was needed for a 10 day holiday and was only 120kg of the weight limit.

    Hello. Some say it is an alko chassis and others say it's a "similar" set-up. If you have an Aviano I think I will go by your own assessment.
    I must say I am slowly getting more despondent with what I am reading with regards weight capacities.. Surely a m/bike rack fitted by a known specialist should be easily able to take my 125kg yamaha? What's the point of a 100kg limit?
    Like you I will load the camper with what I will normally be taking and see what transpires. I will keep you all posted.
    Thanks again to all.
    :Eek!:

    Why dont you put motorbike on then nip up weigh bridge and see what you have on axel loads then bungee push bikes on then check it again
    Better than spending money on something that may not work

    Thanks. Looks like I'll be trying a few options but I'm determined to get it right.
    Would anyone know if it come to the worst whether I could have the camper replated at a higher weight or is it just a safety issue which cannot be circumvented?

    My Burstner Aviano i684 had an Alko chassis.

    It was also plated at 4000kg but I wouldn't have put a motorbike on the back, not with the amount of [STRIKE]shi[/STRIKE] stuff we had packed in the boot.
