    So, I don't post alot on this website because I spend more time in my garage then on the computer but I do visit this website on a daily basis. The airhead dirtbikes section has inspired me to build one,So i did.
    I am 47 and race both modern and vintage bikes in motocross, I have a 07 KTM 250F and a 80 RM 125 that I will be racing this year in ACRMX as well as AMA Dist. 34. In the ACR series there are a lot of unique bikes but I have never seen a BMW race, So I guess it will be me!!

    I started with a 79 R 65 that had been slightly modified, But basicaly started from scratch. I removed the whole front end and installed a 02 Yamaha 426 comlete front end and wheel.I installed 2 18''Progressive Shocks in the rear in a laid down position to get about 8" of travel and gusseted the frame. I had to make up a new sub frame to support a seat from a 80 RM 125 I used a gas tank from a 77 Bultaco Pursang and side panels from the same. I have always liked the look of the bumblbees so I had custom stickers made up to go for that look. I made a custom exhaust that is 2 into 1 that exits into a Yoshamira(sp?)silencer up high. The bike is going to be street legal with removable lights for MX. The bike has come out well above my expectations mostly because of the inspiration of this website. I am working on getting photos up just don't have my own camera.

    The bike had been modified by po ( user name Clang) It had a 80's? Yamaha front end on it, I thought it was very light for the weight of the bike. I only had to make up some spacers on the lathe to make it fit. It was the easiest part of the build.

    One thing I have to say is the amount of time it takes to do something like this is unreal,I tried to keep everything as simple as possible and removed everything that was not needed. I probably have 100 hrs. in total time into it. Not to mention $$$$$

    The way is soppose to Be but be careful you can get somehow addicted..:yikes

    well just make sure you have the camara then

    I don't know if you know this but BMW race and also won the ISDE for at least two years in the early 70's on heavilly modified R65 (I think) you can look for the exelent articles at VMX magazine from Australia (The best moto magazine I have ever seeing)

    Oh my freaking God, all that sounds exelent

    are you ussing the "Skinny" R65 engine or something wider
    That is a great idea
    Most exelent, I love the "Snowball" effect coming loud down the Mountain..

    did you get to test ride it so far..

    how was it..!?!?:ricky
    "just don't have my own camera."
    A true Sign of a real Crafsman, all the money spend on tools and materials I can assume.

    maybe we need to get you one, I just give my old S400 to my friend JP so is not impossible, since I was tyred of seeing his amazing work come and go with out bieng document it..:bow

    actually is a shame you did not have a camara to take fotos of the building process were the real beauty of the exercice, resides at least in my eyes

    maybe post the area were you live and another member can go and help with the picture taking:feelgood


    Also I you need a place to HOst them I have room at my smugMug galleries if you like, or maybe King baldy can give you his blessing since i'm sure you project will bring tons of inspiration for others.

    i remember clang.


    and you say a yama 426 front end was a bit light for an R65, in your opinion?

    Sorry-- re-reading it-- the 426 is on it now.. clang had some other '80's yamaha front... You like this better?
    How much does the whole thing weigh?

    cant wait to see pics indeed.. you must have a friend with one!

    btw: did you go with the single spark heads, or the twin spark?

    Amen brother. I've run across the time involved issue thingy doing wheel swaps with different axle, bearing , spacers, offset of spoked wheel etc.
    My last swap was to spoked SMC wheels to my DukeII . What a pain in the ass that was!!!
