Angry Sub frame bolt

With all the problems with the sub frame bolts breaking off, what would be the disadvantage of welding them? It just seems to me that it would take care of the problem. I'm just asking, is there a reason for this frame to made to disassemble? Thanks for any replies

I see that as doing something for no real good reason.

If the bolts are properly torqued and a bit of LocTite put in for good measure, the bolts are checked at least at every oil change and the rack is not overloaded there is no reason why the bolts would come loose. Bolts that come loose, even footpeg bolts, are a sign of poor maintenance. There's just no nice way to say that, but it is true.

If you have a Gen 1 then an upgrade to the same bolts used on the Gen 2 would be a good idea.

The downside to welding is that you can't get the airbox out should you need to, you can't easily replace the rear subframe if it gets tweaked, and you can't sell the bike to anyone you know (because they are going to cuss you out at some point for welding the subframe on).

Thanks for your reply, that's why I put it out there. I have never tweaked a sub frame so I didn't think of that. At my age I don't get real radical like I did in my younger years, still enjoy getting out riding, it never gets old.

If a jacked-up pickup truck rear ended your bike at a stop light you might very well need to replace a sub frame.

At that point I would have more than a sub frame to worry about. I see your point, Thanks

No need for a welder.. That would be a big mistake.
Take them out one at a time so the holes stay lined up. Degrease the nut and bolt with brake cleaner and let dry. Add blue Loctite and torque to spec. Do that and chances are you will wear out the rest of the bike before any issue with those bolts occur.
Tight bolts don't shear. Loose ones do and usually wallow out the frame holes before the bolt actually breaks.

Never pick a fight with an old man.. If he's too old to fight, he'll just kill you..

sub frame bolts

Hey Guys, I would like to thank all who sent replys. Every one was good. It sure made me look at it from a different angle. All the trails (around Omaha/Lincoln) as I knew them have been replaced with houses and so now I am left riding gravel roads and ditches. I will post later in the spring what route I will go. All of you who responded had good answers, food for thought. By the way, the bike in question is a 2017 klr 650, bought new at Champion Kawasaki in Sioux City Ne for $4995 out the door last Sept. This is a good site for infro and you guys make it that way.. Thanks again guys
