    not just a crack, but a fracture of that mount, and your theory is that the engine rotated in the engine mounts with enough energy to do this damage...hmmm.

    possible i suppose, but if you look at the way the engine is mounted in the frame, it would seem to indicate that a rear mount would be broken too. there's not much play in the rear mounting points once the bolts are in place, and the bolts are high tensile.

    HMMM.... Time for a great BIG skidplate I think. Long and wide to cover all the way back to the dog bone. Enduro Engineering claims they can make one for any bike:deal. Nasty of someone to leave a ditch across the road:eek1. Was this a firebreak that was not re-filled? Glad you are OK .

    The rear mounts are fine and a lot stronger then the front. The motor is consider a part of the frame. The back end took the blunt of the impact and i guess it was hard enough to make the weakest link give. Thats my theory but who knows.

    I'm going to put a skid plate on it but don't think it would have helped in this hit unless you tied it into the frame and that would take a lot of fad work, Some of the roads on LBL are not maintained and this was one of them. It was a wash out and would not have been a big deal on a dirt bike but it would still have a pucker factor at speed.:rofl

    Like I was saying...these big behemoths don't slow down on dirt all that great but they do really move. You really have to assume the worst thing that could happen is in the road in front of you already. I usually ride my Strom 10 mph slower than my real dirt bike. I also don't ride it when everyone else has their real dirtbike,only with similar bikes. That way everyone is dealing with the same disadvantages. I would still figure out a way to get a big skidder on it. Look at how it is done on Weestroms.

    Man i have tried a few times to down load my video to you tube but no luck. I don't understand why it keeps locking up. I will try to shorten it tonight and see if that works.

    Looking at the design i can see how a downward jolt of the motor causes that. there's quite a horizontal lever there. It looks like we could install a bolt that runs all the way across both motor mounts to eliminate the torque on these mounts during an impact.

    The video was a bit spooky with that huge log on the left and the tank slap. yikes:eek1

    I think that would work or surely help but i hope i never have an impact that big again.

    if you keep riding that thing like you have been, better think about some wire wheels!

    i was cleaning up the bike yesterday and took the opportunity to look at the engine mounts again. man, when you look at that crack and calculate how much movement it takes to create it...all i can say is i suggest you inspect that bike very very carefully.

    I went over it good after i spotted the bent wheel. It did bend the kick stand too. but who needs a skid plate with that muffler under there. only one dent in it and that sucker took a hit.


    Ktmklx.. I think i'm going to slow way down, that was a warning .


    Dooga ..Thanks man it's a work in progress.

    And a "rider" on your health insurance policy:deal. Just drink while you ride on the other hand.... then the compound fractures do not hurt as badly:eek1. At least immediately.

    DUDE that is NOT a real dirt bike. Slow down and RYOR. Your buds will wait for you.

    His "buds" are the ones telling him to get his ass in gear or get out of the way! :evil


    I've ridden with 2fast since, what, around 1974? Even when he takes it easy, he's flying! Mountain story, he was following me on his Street Glide down a mountain switch-back road. In one corner, I heard a grinding noise and just KNEW he went down. I looked back, and he was right there dragging the floorboards off that Harley.

    "Riding His Own Ride" is quite a few clicks above average.

    I was thinking about that crack on the engine mount. When I was a kid one of the engine mounts on our mini enduro broke off, and after it was welded back up my dad put softer bolts on the mounts. The theory being that the lighter duty bolt would bend or snap rather than taking off a mounting point again. Never broke again that I remember but maybe something like that would actually work? No way of knowing if it really helped or not though, could have broken either way
