Hole in sump, need a stronger bash plate

[donaldb]

I have the rumbux bash plate, but this weekend, riding through lesotho, I hit a rock, and the plate did not protect.

The drain plug was hit straight into the engine, fortunately we got it out, and glued it back with prattleys steel. This area is extremely remote, and luckily managed to get oil from a small truck driver. Was diesel oil, but still better than nothing.

My problem is the lack of protection in this area. The rumbux got reshaped and tore.

Also this weekend, to box mounting system failed, on the bike side.

Well send photos later

Incredible... Rumbux looks so solid!!

You've got only two other options: the Ride on Adv or the ACD, i think the rest aren't so strong.
I have the new ACD and I haven't had any problems so far.

I was surprised to read you did that with a Rumbux. I thought that was a heavy duty piece.

Some being better than others, depending n the size of the rock and the downwad force, no skidplate is impervious, especially aluminum.

And in Lesotho ! of all places !! ,,,where were you? going up God Help Me Pass ? or doing the famous Sani pass? ( I'm ex SA )

 

[donaldb]

Lol, no, afraid not Sani, done that, and this weekend was more extreme than sani.

This happened in the centre of Lesotho, so was quite concerned, although as the saying goes, more tales to tell.

Have a prelim on YouTube, not compete yet.

An going to call rumbux in the morning, find out if they cannot make the plate out of stainless steel.

Hiked around Semonkong down to Maletsunyane Falls, so, if you were riding close to those areas, no wonder you holed the sump guard - jeepers !! Bastervoetpass !...now you're making me homesick !! Nice

The Chinese are there building massive roads, it actually happened not far from semonsking, on the way directly to matatielle.

The roads I was travelling on were being built, and could be tackled with a 4*4, so no where near as bad as baster.

Either way, need more strength underneith. December going to Mozambique, although there is more sand than rock over there.

Suprised to hear the Rumbox gave in but then hitting a big enough rock is like hitting the plate with a sledge hammer.

What we need is to find some flush plugs and pad the bottom so it can take a hit.

Sounds like quite a ride! Just noticed you're in SA. I can probably have a skid plate made from Stainless Steel if you want one. PM me with your phone and tomorrow I'll see if I can get a quote on cost. There has been a guy in SA that has a S/S skid plate made for his Rumbux bars. IIRC, he was a true RTW rider and wanted the extra insurance. Ideally, a waterjet cut piece would save a lot of time, but most any fab shop should be able to make one up for you. I can only imagine the damage you'd have had w/o the Rumbux, or with a lesser skid plate design.

Though, as has been said, as some point, nothing will save you. The beauty of the Rumbux is that the skid plate is supported by the lower bash frame. However, it's still an aluminum plate spanning steel tubing. A hard enough hit will still do damage. I suspect only Ride On ADV's skid plate is truly bomb proof. 1/4 aluminum plate doesn't flex. You may grind it down some, and with the right hit, it will fracture, (Aluminum fractures before steel, part of why the Rumbux uses the combo of steel bash frame and aluminum skid plate, a little give will absorb more energy before damaging the bike's frame).

1/4" 6061 T6 aluminum won't fracture from the weight of the SupaT. The stuff Jaxon is using is some pretty tough stuff.

Unfortunately though, many call these "Bash Plates," which is a misnomer. They are "Skid Plates," and are mean't to help slide over obstacles by creating a smooth surface. On 4wd vehicles, we use 1/2" steel, because aluminium is just not stout enough. Aluminium is a great material for bikes because it is light weight, unfortunately though the S10's weight is not really the factor, it's the downward force that is applied and is greater than the weight of the bike.

It will take a really significant impact, but if you look at the data, steel will bend when aluminum cracks. It's a material sciences thing. Fracture rates are on a curve, (very generalized), and fatigue rates and vibration, stress, force of impact, etc, all lead to aluminum cracking well before steel.

I have a little experience with these things. 25 years as a machinist, the last 20 in the hydraulic tools industry. I've seen a lot of broken stuff. As I said though, Jaxon's skid plate is bombproof. The point was that anything can be damaged, given the right conditions and parameters. At some point mechanical empathy becomes an issue.

Yep, for sure. But never the less, ours comes with lifetime warranty. So go ride the bike like you want and enjoy it !

Life time warranty on a $700 bash plate doesn't help the destroyed $5000 motor though! Your plates certainly do look damn tough though!

I didn't know they were that cheap!! ???

That doesn't sound like OZ spare parts prices.

Where did that figure come from?

Beautiful area. Was it that rock at 6:56? If so, it looks like a luck shot somehow. Bottoming in the ruts before?

Yes I have seen my Alt Rider plate crack after getting hit from a rock thrown up by the front tire. I was running at speed (60mph) on a graded dirt/gravel road north of Tombstone and as we would drop into the washes there would be softball size rocks.

One or two hit hard and after the ride I decided to do my service. Pulled the plate and had a 1/2 deep dent with a crack down the middle. If Aluminium gets hit hard and fast, it cracks.

This hit was in direct line with the tab that hangs down to mount the stock plate. If the rock would of been a little bigger my pan would of been compromized. Thus http://www.yamahasupertenere.com/index.php?topic=6266.0 I did this.

I like a plate that will take a hit but I also want it to absorb the hit and not tranfer it to other points.

Nope, did not have the camera on at the time of the incident
