Most reviewers had criticised RE for using these nuts and bolts instead of allen bolts with threads embedded in the chasis frames. Interesting how those critics never got invited to forthcoming RE events. This is some serious point you have made.

You can use 2 nuts instead of one. That way the bolt won't loosen up. I have observed this in many other machinery where much vibration is involved. Even you can see this type of 2 bolt hold system in many bike's swingarm ends.

Thank you for sharing, I do not own a 450 but am planning on in the future so good to know this issue.

Use a locknut

Thanks for a well researched video. Few things I would like to point out (not an RE owner). Most RE dealerships are pretty lax about following company specs. I doubt that RE has even issued any specs on how to mount the crash guards on their bikes, especially if it involves removing the bolts that mount the engine to the chassis. They always end up over tightening bolts which can lead to failure. Also, I feel that the blue 243 Loctite is not the right product here. It is a medium strength thread locker meant to be used if the bolt needs to be removed and put back. I doubt that the engine/crash guard bolts ever need to be removed. Here the red, high-strength thread locker would be more appropriate. Also, the bolt with the nut should have been mounted with the crush washer and/or a split or cotter pin. This would prevent the bolt from falling off even if it comes loose from the nut. I would imagine these engineering issues would have been resolved before the bikes cam to market.

good observations and suggestions hope RE Team looks into the issue seriously and the valid suggestions made by you.

I heard in some youtube video that there is and new sop for himalayan 450 for right side pulling issue, they have to loosen all bolts where frame is holding the engine and adjust the engine angle to align with bolt holes. so service center might have to remove these bolts while performing that SOP

Ye sare bolt kitnay torqe per kasna hay kirpa bataya Sara🙏

Which shop you visited in the video?

High quality bolt + Locknut should solve your issue .. locktite will also hold the threads.. n secure everything.. provided the bolt is not elongating over the time ... Not a big engineering issue ..

As you mentioned, locktight company said..."this is something that Should work" , that means they are in doubt that it will work or not?

can we use tooth lock washer or spring washer instead to c clip?

just something that I noticed on my Himalayan, rocking Mototorque crash guard for past 1200kms, when I was riding back from Wai to Pune started feeling some viberations on my handlebar to be precise near clutch lever and left end of handlebar which previously were absent, first thought that came to my mind was a loose bolt somewhere on the handlebar or forks, so tightend those at home, still couldnt get rid of the vibes so took her to service centre where the mechanic pointed out a developing gap between the chasis and where the crash guard was pointed, and that scared me shitless, RE guys did some bickering about this is a 3rd party crash guard you can face problems and stuff, but eventually the guy tightened the bolt the one on the right side "the bigger one" Vibrations after that are very less, havent use locktite yet, thanks for trying it out on your machine first, please keep us updated on it, meanwhile I need to keep one eye on road and one on that bolt

The bolt on the lefthand side is a 10.9 grade with a yield strength of 940 MPa (made of Stainless Steel). It looks like a M10 or a M12 bolt. Industry standards for M10 10.9 grade torque is 75Nm and for a M12 10.9 grade it would be 135Nm. I suggest you go back to RE and query them on this. Another option is to use Loctite 243 in conjuction with Nylock nuts.

This is Heavy Duty and is not easily removable with tools and needs a heat gun, hence strongly recommend Loctite 242 Medium Strength Blue which is Removable with tools.

that is too much loctite. the bolt may break if you have to ever unscrew it. better use a metal washer lock nut it did break when i tried to unscrew the handlebar bolt

sir can you specify the bolt sizes and types that provided by mototorque and RE ?

Lock washer under the nut will prevent back out. On the other bolt use lock washer under the bolt head. Also that first bolt you showed was definitely spalled. The thread was flattened. Replace bolt in that case. Follow proper torque specs and use Loctite. I have RE and the factory uses copious amounts of Loctite that's for sure 😊.

Great research...
