Title: Motorcycle carrier systems . Advice
Post by: 73 Peanut on March 22, 2020, 07:04:05 am
I have looked at a few motorcycle carrier systems that attach to the tow bar but would like to know if anyone uses one to carry a 200 - 250 kg motorcycle behind there SUV . Do the cops give you a lot of grief .

I carry all my bikes up to my 790, so ~200kg, on a rack I made which is mounted to the bumper (hence also towbar-bolts) of my Landcruiser bakkie.
It mounts with 6 large bolts: 4 on the towbar-group and 1 each on the side to the bumper i.e ladderframe of the vehicle for stabilization.
I know it will take an even heavier bike but a BM boxer will not fit width-wise.
The bike rides on/off via a ramp with me alone doing this, I need no help, and I clamp the wheels via turnbuckles.
Then a few tiedowns do the rest to stabilize the suspension preventing it 'bouncing' on the springs.

I made this rack myself hence know it is seriously strong enough, and the inspiration was the Xramp principle... but this system I think is way too flimsy for anything bigger/heavier than a plastic.
A cruiser is also a big-enough vehicle for doing this: a plastic loaded I don't feel, neither my 701, but the 790 I do notice a little, especially offroad.
I've been asked quite a few times already if I won't make some of these racks due to the simplicity of loading as well as fastening the bike!
Answer's No, pls make your own - look at an Xramp, make it stronger AND attach it to the ladderframe (sides!) of the bakkie so as to prevent longitudinal rotation (twist). And yes, a bakkie would be your minimum, forget any cars.

After I made it I stopped at a few roadblocks where several officers were present, showed them this contraption on the back of my bumper (it makes the vehicle some 75 cm's longer) and asked if this is going to be a problem legal wise.
NO was the unanimous answer I got - and do note that the wheels stick out a bit either side - they all thought this was perfectly legas plus a nice thing to do.
I've 'doubled' the lights & numberplate etc, plus a plethora of reflectors make it a christmastree at night when headlights fall on it.
Because the cruiser is rather high I look over the bike from my rearview mirror, no problems in this regard.
Works super, can recommend it!

That is a awesome rack and I am going to do the same and add the lights . The X ramp does serve its purpose but I also thought that it looked a little flimsy for a heavier bike .

You're welcome to come have a look for any ideas, after all I sortof copied it too: @Runner has an Xramp and suggested I at least had a look, and of course I did.
I'll never admit he had a good idea though, so don't tel him pls  :P

Excellent unit Burp, great fabrication  :thumleft: I had an X-Ramp and fed back some of my own R&D on it as well. Admittedly only used it for an enduro bike and was fitted to a Subaru Forester. Ideal as noted is to stabalize it to the chassis so not just attached by the tow hitch as will inevetably flex and twist. I eventually sold it and reverted to a trailer as there was alot of other kit that could go on it and I could also take heavier bikes and more than one.

I've been toying with this idea as well, my only concern is I think the weight might be a bit much on the rear of a 2.5 hilux chassis? What do you think @BuRP? XR650R is approx 135kg dry, so say max 155kg fueled with the long range tank. My biggest concern actually is damaging the chassis somehow, should I be concerned about that?

Nah, go for it!
The OP is talking about an Elephant, but in comparison the XRR is a Gazelle.... OK, a Kudu but that's still part of the gazelle family innit?  :P
Do NOT make it to fit the bullbar itself (the hook&ball thing) but rather use the square plate with the 4 boltholes of the bumper - which I will presume here will be an aftermarket steel affair like mine is.
This bumper should connect to the chassis rails, and you make sure it cannot hinge here.... by perhaps extending the connection plates so that another bolt through the rail can be used: 2 bolts each side prevent hinging hence you can put load on.
I'd not worry about the chassis itself but do keep the bike as close as possible to the rear wheels/axle - like I've done, the handlebars would interfere with a canopy but I don't have or want one.

Then lastly, if you hammer your Lux' over speedhumps and/or offroad to such an extent that the Pig would be launched into orbit if not tied down and the chassis bends then you obviously will dislike me and wanttomoer me.... but I'll not be home then  :lol8:



PSst: I've used a very similar layout for the 'channels' (main gutter & ramp) but have increased the height as well as material thickness. This makes for little extra weight but massive strength gains, I can only recommend doing same.

Being busy making myself a carrier for my motorcycle which seem to be turning out ok but  but  but my tow bar is weaker than my carrier so please check your mounting points and brace where possible before loading a adventure bike.

Finished building my carrier for my bike but now I need to fit stronger springs as I clearly did not think about the fact that I have a short wheel base which tends to show the weight more on the rear . At least it filled some of the lockdown time .

My version I build to carry my trials bike.  I would be worried about road holding with a 650GS.  My NP300 steering starts feeling vague with just a 75kg bike and the +/- 15kg of the rack.

This is mine that I built about 10 years ago. My KTM 625 SXC goes on it, complete with long range fuel tank no problem. I made it so that it fits into the back of my double cab when disassembled.

What do you think of this type of carrier?
Bought just before lockdown to tow my Honda XR 400R and have not used it yet.

I am doing a mod to help strengthen the tie down method, but I am still not convinced on the safety for a long trip / tow (+/- 200km).

If you are going this route, remove the chain before you tow. Also, unnecessary wear on the rear tyre I think.

Macker, I used one long ago for a YZ. As Kortbroek mentioned, remove the chain and also don't turn to sharp, or try to reverse. Not good for the tyre over long distances. Does your front wheel touch the rear door?
Title: Re: Motorcycle carrier systems . Advice
Post by: 73 Peanut on April 09, 2020, 03:50:11 pm
My only concern with just clamping the front end and letting the rear turn is if it's dry sump is that components are still turning with less oil to lubricate and cool which should do some damage over long trips . Am I correct  or not .

I'd rather put the rear wheel in, and let the front wheel do the rolling - tied down straight of course.

Will definitely take the chain off, and would not try reversing, could end up under the car.
 The front wheel is very close but doesn't touch the car, why do you ask??

Never thought of that, I reckon that would improve tight turns as the front wheel would follow the direction of the car.

As a student I build a hitch like this on my old Honda Ballade to take my bike up down for holidays. One difference, I took the frontwheel off and put the bolt through my attachment, wheel ride in car. Somewhat of a mission but it was to limit the extension of weight on the small car's towhitch. Did many many km's that way. Just remember to release rear brake and take chain off.

In addition (since I've owned two different hitch racks), I stored the RAMP inside the car; although it has lugs for attaching it to the rack, it is HEAVY, and just further reduces weight on that hitch.

Just had a thought, if the bakkie runs out of fuel, you could have some-one sit on the bike, and "push" the car from behind! Very versatile attachment imo. You would just have to put the chain back!

Ek het in die tagtigs 'n heel paar keer my XT250  ook so gesleep. Kon nie 'n wa bekostig nie.

Neem die volgende in ag:
Natuurlik moet jy die ketting afhaal.
Die Rake angle van jou fiets speel seker die grootste rol in die wyse waarop jy hom vasmaak. 
Sodra jy draai, hoe skerper hoe meer,  gaan le die fiets na die butekant toe.
Die toue moet in lyn met die skokbrekers vasgemaak word anders; Oor 'n bult trek die toue stywer en deur 'n lae punt (soos van die petrolpompe tot op die pad) raak die toue losser. Daarom is dit risiko om die toue aan die handles vas te maak.
Neem in ag dat wanneer jy ry dat die fiets se wiel op die middelmannetjie loop. Slaggate kan nogal lastig wees.
Alles loop gewoonlik lekker tot die eerste koekie begin krummel, wees voorbereid daarop. Vinnige swaai bewegings van jou voertuig het 'n direkte effek op die fiets.

Voorspoed en wees versigtig.

@Sommer Ek, more, thanks for the advice. Ek het die pos 90% verstaan maar my Afrikaans is nie baie goed nie. Could you explain what the highlighted section above means please.....

Macker let's hope my English is not worse than your Afrikaans.

If you put two bricks head to head about 5cm apart and you lift the outside end of the one brick the measurement between the bricks at the bottom will still be 5cm but it will measure less than 5cm on top. The same happen when the front of your vehicle is higher than the back of the vehicle. This will shorten the distance between the handles and the fastening point  of the ropes on the towbar.   It will be ideal to only tighten the wheel to the carrier, or if you have a hollow front axle  to use a pin through it as a fastening point.

If I remember correct myprocedure was the following:  Get car and bike on level ground. Put front wheel on Carrier. Ask wife to hold bike upright. Thighten ropes as fast as can. Lift back backwheel of bike on to a can (about 25cm) See to it that the ropes are stil reltively tight, a bit more than only staight.  As I then take out the bucket the bike will tighten up. Make sure that there are still enough play on the shocks,  I tested mine by hooking it in the driveway and then used the little uphill to the garage.

You will never really get rid of Pythagorus but you must try as close as possible. I hope it help. If not Ask again.
