baja on a sidecar

My friends too off for Baja a week ago.

3 650's and on GS800. The GS 800 returned home
on the second day with an injuried rider. The 650's all made
it ok.

Next year I will make the trip with them on the
1150GS sidecar. They are having doubts that I will be
able to handle the soft sand.

Ok, who has done it and what do I need to do.

Background.. 40 plus riding dirt and street.. 3 yr on a
side car. The really soft sugary sand is where I might sink
or would I?

Baja

I have done a lot of riding in Baja on sidecar Rigs......The first being in 2004 on a 1150 GS Rig. I found the soft sand to be impassable on the GS due to the weight. Now I stick mostly to tarmac although I have done easy stuff like Coco's even on my ancient R100 EML.

I've been riding & racing in Baja since 1969 and have been stuck in soft sand/silt in just about anything you could imagine. Scott Whitney seems to do just fine in the sand dunes with his rig built for Dakar. However, the silt beds in Baja can seem bottomless and it is possible to stick a 4x4 in it if you are not careful. Silt is much worse than sand, even the so called sugar sand. The silt is more like flour and you easily sink up beyond your ankles walking in it.

Do you have car tires on all 3 corners? Airing waaaaay down to 8 to 10 psi yields maximum floatation when stuck. The guys who race the limited classes in Baja commonly use strips of carpet to put under the tires after getting stuck to act as ramps so a little speed and momentum can be built up to get out. They do a neat little trick of putting the carpet on a lanyard to you don't have to stop and walk back for your carpet. Maintaining speed is critical as is limiting how sharp you try to turn. Technique goes a long way when dealing with sand & silt.

I would think that much of Baja will present large rocks/cobbles and wash outs to be a bigger challenge than sand. But that's Baja, the terrain changes often.

Here is a pic me in 2010 in the Oshkosh entry at the Baja 1000, I'm the one with the day-glow pink shade strip on my visor in the right seat. This silt was only about foot or two deep down around Punta Conejo:

I've had my old DR rig at the beach in the Outer Banks (NC). I was able to make it but did get stuck once. Luckily my brother was there to pull me out with his jeep. I was running >10 lbs of air in all three tires. The hack wheel would dig in and pull me to the right and mess me up. I've been there before on the same bike (with out the sidecar) and had no problems.
Ive never been to baja but Im sure the silt would be much worse.
That said, Ive seen pics of some of the crazy guys riding Down Under with big heavy rigs across the outback.
Maybe mount a winch on the front of your hack.


Is there a particular need for the sidehack? Sounds like it would be alot more fun on a smaller solo dualsport bike. (Just asking, not trying to be a jerk)

Yes, but that is with an aired down 8" wide BFG Mud Terrain tire on the back, pretty big car tires front and side, and 100hp. Flotation and momentum are what gets you through. As Strong Bad said, silt is different than sand, and is generally worse, especially if it's deep.

These guys, with skinny tires were having a different experience:

Fat tires for flotation....keep moving if possible. If you stop take off easy. If you have room carry some conveyor belt or similar material that you can run up on to get moving. Two pieces are good as you can leap frog them if needed.
A winch is okay but you will need a deadman of some type to hook to which can be a challenge. Carry a shovel. Don't stop in the wrong place if near water when the tide is out for obvious reasons. It is no fun to watch your rig establish a water line on it when you can't do anything to stop it. LOL. I am origionally from Florida and my experiences here are base d on beach running and in surrounding areas so maybe there is better advice for Baja.

Here is a great discussion from a group of desert racers about silt in low HP cars, including an awesome vid of a gal totally new to driving a race car in the silt.

Good article.....Being from Florida sand is not foreign to me and I can say that what was said there is dead on. My previous post related to these truths somewhat.
All 'sand' is not the same. Some seems almost bottomless
Years ago we built quite few .dune buggies down there. VW powered and pretty light. Momentum was our friend especially if sand was mixed with muddy areas. The 4WD guys went through the mud pretty slow but us buggy guys blasted through it. If you didn't you were done. Sometimes the buggy and 4WD guys didn't get along all that well LOL.
Heck a buggy at speed with a flat bottom pan on it could hydroplane across areas that would stop all but the near monster truck type outfits but God be with you if you didn't make it....LOL.
Just sayin'
