    Yeah I ground off the SE plastic guard mounting tabs and installed it. It is starting to wear thin at the bottom mounting tab from the front tire rubbing on it. I think that is just the price anyone is going to pay if they run a big tire like the Fatties from Golden... and bottom out a lot. If you look at enough SEs you'll notice that quite a few of them have plastic guards that are starting to tear at the bottom. KTM should have made the bike with another half inch of clearance between the radiator and tire.

    No pictures at the moment.

    You could always custom design longer offset triple clamps :)

    So it turns out that Evotech has stopped making the guard everyone uses for the 950sm rads. I've installed a new-ish 950sm rad after mine sprung a leak and keep forgetting to order a guard. Any other options?
    I've found Radguard in AUS but I'd prefer buying something someone's already tried for fit. If I'm the guinea pig I'll buy it today. This part availability problem is a PITA.

    Fat tyres and 7mm spikes against this. Iet's see how which one wins.

    I'm am using the Raguard protector bu for the SE but on a 950SM rad that I had Mylers weld SE rad tabs to. Clear as mud?... hahahaha. It's the best rad guard I've tried so far. @alongat is supposed to be working on one though that should be even better!

    I think @PowerCell might be working on getting some aftermarket radiators made up as well.

    I owe you thanks. I bought a spare rad because of this thread. Saved my butt when mine busted!

    C'mon @alongat! I'm sending an order your way for some of the other goodies--love it if you solve this too.

    Yesss. I bottomed it a few times, only small scratches.
    Note the gap between the part that is bolted to the radiator and the hook thingy.
    When the sump gets bashed upwards and the gap closes, the force gets transmitted to the radiator. Not good, so I cut some more space there, so that the hook can only touch the front side of the curved plate. In the first pic it is not cut, I actually noticed it when I had sent the post.

    One thing to be careful of when there is nothing supporting the radiator from the bottom is the top mounts will stretch out and rip the top part of the radiator. Ask me how I know.... It's kind of a damned if you do and damned if you don't when you use or don't use the bolt that connects the radiator to the sump.

    Thanks for the warning. I'll try figure out something or just hope for the best.

    Just keep an eye on your top two tabs.

    I thought some of the bash plates have additional mounting points to give some protection to the radiator (at the back and maybe under the engine??)

    Some bashes, for example the stock version bolts to the bottom of the motor but I doubt it keeps the sump in place when you land the big ballerina on a rock. Mine bolts to the centerstand stopper bolts at the back and to the sump in the front. The center mounting point is annoying to use and forgetting it allowed me to route my oil lines so that they dont get between the bash and the engine and split.

    If you ride offroad you are going to get some movement through the skid plate to the sump almost no matter what. I think the Lake monster Skid plate mounts to the center stand holes, the center engine hole, and the sump. Some people don't use the sump bolts and that would probably be the best bet.

    I used a sm radiator, only one fan on high right. ( Doesn't work very well )
    Then I move the radiator 22 mm back.

    I’ve the course of the next few months, I am planning to produce:
    1- hi flow replacement radiators with heavy duty mount tabs (these will not be cheap)
    2- replacement bolt on fan shrouds using higher output (larger) fans. A warning: this will make front cylinder spark plug changes and front valve clearance checks more challenging
    3- radiator crash guards
    4- oil cooler for those using rally fairings with enough space
    5- dual speed fan controllers (hi-low fan speed)

    I have no plans to reinvent the front radiator screens. There are metal grill ones available if you don’t like the original plastic ones (which I actually like).
