    Thats what I posted first, then I saw it was his first post and thought I should be a little more constructive :lol3

    But seriously, the fact that you put "can go off road" 12th on your list... I think something more in the dual sport category would suit your needs better.



    ...and speaking of constructive, I'll take this opportunity to say awesome work harcus. How would a giant loop (the big one) look on that rack you think?

    Harcus, nice post.

    As much as I like my bigass dirtbike, it seems a bit heavy and long compared to your light-ass dirtbike. And the 3 hunny squeals at 65 mph. Maybe I need a 'tweener, the right iron for each stroke.

    One criticism though -- Too shiny and clean! I'm sceptical of the extent of validation testing. Maybe I can help you with that.:evil

    This coming President's day weekend I'll be heading down to Yuma, Az to do some camping off my bike. I'll get some pics and let you all know how it works out..... Dual-Sporting the 500 should be interesting......

    Your fabrication skills are excellent and are matched with fabulously well thought out designs.

    I have thought about trading my '07 525 EXC for the new 500 EXC but I cannot see a clear advantage to my well set up 525 (now a 565) so I am watching this thread to see how the new FI works and how you think the handling compares to the older 525 design. My dealer said of the FI to just forget about it failing since it is well proven now. "If you are going to stress about this just get a spare injector and carry it in case the stock one plugs up from crappy gas."

    For those who worry about engine reliability I would note that I ride with a guy that has an '07 525 EXC with 16,000 hard DS and racing miles on it. He just changes oil once in a while. Since he is finally running to the end of his adjustment on his intakes he is going to go with K-W stainless valves. (The valves in the new 500 should last as long as the K-W valves.) One engine builder I talked to said that most of his 525 engines go at east 30,000 to 35,000 miles without ever needing any work except checking the SS valves once in a while. When I asked him about oil changes for DS riding he said, confirming what FTB said, "Oh, just change it when you can. 1,000 to 1,500 miles. And run good oil. Motul or Rotella T. The HT oil cooler is nice but probably not needed for DS riding. You probably won't be hammering up long, steep sand washes."

    For those that worry about sub-frame damage I can only say that I have tested my stock one in every possible way without damage. I watched one guy flip his 525 MXC on a double jump with it landing on the rear end of the sub-frame. He broke his rear plastic fender. The 500 should be just as reliable.

    Great thread!

    Any update on the camping trip? How is it for a bit of a slab day getting to the good riding?

    Thanks

    My neighbor purchased my '05 250 EXC 2T and flipped it over again. This time he broke the rearmost extension off the right side of the sub frame, the piece that supports the rear of the plastic fender. He bought the new fender pieces, took the sub frame off and had the broken piece welded back on for $45.

    So I have seen one break. You have to work at it, though.

    That's a great question. I've been testing the lights in the fairing. No problems with overheating (it was 86 here in Ft. Lauderdale last week). The low beam output is adjustable so it reduces the heat generated in normal riding conditions like during the day, it's also only using a couple watts of power. Hit the high beam and both lights go to full power.

    I've never intentionally ridden this bike at night due to the crappy stock lighting, problem solved with the LEDs. The faring is a great compromise, would I use in a hare scramble or enduro, no, but "normal" riding it will give some great protection and lighting.

    Co-developed by Harcus and I.

    Coming to a webstore near you later this month. Extremely attractive pricing and function:deal

    Plug n play for many different bikes, vendor thread here

    What are the odds of getting just the fiberglass faring only with no holes drilled in it I am doing my own headlight mod and it would save me some time if I could just modify a blank of yours.

    May be available in a few months but not anytime soon. Suggest that you read more about the lights in the fairing, I've not seen another product in this form factor that produce this much light. With a couple of model 60s you are looking at 7200 lumens on high beam:deal. PnP means a simple install.

    Ok thanks for the response sir, I will go back to the original plan then its not that big of a deal. I just saw it and thought with a blank I could save a few hours.

    7200 lumens is very impresive. The 2.4 AMPS per is good to. The thing for me is that the light pattern is a circle and two of them stacked just makes a laser beam. For the majority of the world that will be fantastic. I however am a bit more flood than distance minded and only want about 200-300 meters in front but I want at least 20 to 30 meters to each side. That is why I have gone down a different path.

    The PNP feature is a great feature,

    I wish you folks the best sir I am sure they will be snatched up. Harcus is a great guy and even though I am not aquaited with you if he hangs out with you you cant be all that bad. :D

    That's one big laser:D

    You may want to read the datasheet on the cree xm-l t6 led. In particular, the spacial distribution graph on pg 7. The XML puts out 20% of it's output @ + 80degrees. If that isn't a flood, they don't exist!

    I'm thinking our Model 60 has a wider pattern than you need, would be willing to setup a test if you want to specify the conditions.

    Thanks, very much appreciated.

    I have been working on developing the new headlight system with John at Advmonster. Here is proto no 2 with some small LED turn signals in test. New brackets in test are behind the mask. Seem to work well...

    [​IMG]


    This is at an BLM area west of Salt Lake called Knolls. I'm out here because there is no snow. Not so closer to the mountains. Can you see Wendover? It's only 40 miles away...

    [​IMG]


    The mask extends above the triple clamp about 8 inches. This is enough to provide good wind protection but not so much as to be in the way when riding off road terrain. This height seems to work well on the 990 Adv so I reasoned that it might work here as well. Turns out that, due to the aerodynamic difference of the two bikes, it seems to be better here. No noticeable buffeting...

    [​IMG]


    I installed my 76 CX GPS on the "trampoline" shock mount to verify that it would fit well behind the mask. All is good...

    [​IMG]


    There is plenty of sand at Knolls (it is the Great Salt Lake Desert) to practice your sand riding as well as the new Big Foot kick stand foot. We all know how well the stock KTM feet work in soft terrain. This is a "pull out the old & insert the new" item. Looks good so far...

    So far, so good. Back to the shop....:D

    What are you planning to put it on? Orange?

    As Sanjoh said, It will be available. I am still "polishing" the rock.

    I have nothing but orange blood in my veins. I've got a just enough legal to be "street legal" 500 XCW. My plan is to only ever see pavement for food or gas.

    I understand completely sir, keep up the great work.
