Tow hitch load

Hi,
Carrying dirt bikes on a rack mounted directly to the removable tow hitch. Seems to carry fine.
However, what is the max point load the hitch is rated for as there is quite a canterlevered force from these.
Thanks,
Michael

Methinks Russell is bang on, however after my experiences with a removable tow bar i wouldn't use one to pull a helium balloon let alone anything i valued.

Yep - 150kg nose weight refers to the load a trailer exerts on the towbar at the ball centre. Therefore, whether swan neck of fixed it MUST be able to withstand the same load.

HOWEVER, the flip to this is that a motorcycle rack is not exerting the force through the ball but is infact a cantilevered load which effectively extend the reach of the swan neck - or load centre of the fixed if you see what I mean.

To do this technically you could need to calculate the load the bikes distance from the vehicle actually generates on the towbar but I would listen to the above advice - do not use on a demountable as you are also going to be generating terrific side loads as well. Fit a fixed bar and travel with confidence.

Remember our hitches are not the swan necks you guys have. I think they would be more robust. Idea

The Brits have answered and they are correct for UK vehicles but Aussie vehicles have a 350kg tow ball weight - it is in the Aussie supplement.

The Brit goose neck is considered sub standard by Aussie authorities and we have our own (I believe similar to the US design) 3 piece arrangement.
