Unlike most of you guys - I Crash.
I crash hard.
Bend a lot of bar mounts in the process -
Do you have any tips - besides don't crash - to stop this madness ?

The Ride Engineering mounts I have are a single joined top and bottom mount vs the individual bottom mounts on the stock KTMs.

The Shop
Rubber supported bars with solid cones. I absolutely love mine, especially with the green polymer.
...another vote for luxon
Billy at Luxon makes an awesome product. The previous gen KTM triple clamps are on sale for $299 which is a crazy deal comes with ti hardware bar mounts etc.
Went with a replacement set of X Trig PHDS and they'll do fine for now, but obviously aren't ideal.
Buy the Luxon ones

Replacement shafts are like $6. It doesn't stop them from bending, but it is a cheap solution.
Please elaborate. Genuinely curious of your opinion. Personally I’ve had great success with their bar mounts.
The best design for a bar mount I've ever used or seen was the RG3 top clamp with dual mounting points on each side.
Does RG3 still make and sell clamps? They seem to have all but disappeared from the MX industry.
The X-Trig clamp and bar mount system is also super strong considering that they maintain the rubber isolated bar mounts. On the other hand, that bar clamp has way too many parts and it's a bit more of a pain in the ass to work on than a traditional type of mount.
I haven't purchased any Luxon stuff yet, but the owner of the company sure seems like he's got good design intuition as well as a good understanding of the analytical engineering process. The way he has the lower mounts tied together on his system looks very strong.
2. Call the guy up and see how that goes
Twisting of the KTM/Husky stock bar mounts is a real issue for most riders. There are various aftermarket bar mounts available to fix this problem. Most work well, but they each have their pros and cons. Engineering a good set of bar mounts (or anything, really) is all about compromise, or more specifically, making the right compromise for your overall design goals.
One fitting example of this compromise is the number of pinch bolts used. We use a “traditional” four bolt setup, two per side. There aren’t really many options here – one bolt per side clearly won’t work (without some odd sort of hook system on the opposing side), two per side is standard, three would be an odd choice, four per side is a lot of bolts (but might work better?), and any more than that gets ridiculous.
From an anti-twist standpoint, more bolts is better. The bars twist up because they slip in one side of the mounts while they don’t in the other side. The rubber cones allow this movement to happen and the bars end up twisted. With more bolts, you can generate more clamping force on the bars, which reduces the chances of them slipping. All good, right?
But it’s not that straight forward… with four bolts per side (like Ride Engineering’s design) it requires a reduction in bolt size from M8 to M6 so everything fits in a reasonable space. But M6 bolts don’t generate as much clamping force as M8 bolts. Four M6 bolts can generate only about 5-30% more clamping load than two M8 bolts (dependent on torque spec used, you can play with our bolt torque calculator available here if you’re interested in the numbers: https://www.luxonmx.com/resources.html).
This brings us back to the engineering compromise I mentioned earlier. Is the extra weight, complexity, and hassle of torquing down twice as many bolts worth it for only an added 1/10 - 1/3 improvement in clamp load? We think not, and we go about fixing the twisting issue in a much more efficient way for an overall stronger and lighter bar mount setup that still allows the use of rubber cones instead of resorting to solid cones (that give a harsh ride and lots of vibration). Our mounts are a bit more expensive than most options available, but if you want the lightest anti-twist mount that works well, it may be worth it to you.
You can read A LOT more about this subject in our blog post I wrote about this exact problem. This should answer most questions people may have, but if not, feel free to shoot me an email!
