    agree a 100 %

    No Bling Bling on ADVenture bikes...

    did you see the motor "Tilt" so the angle of the final drive swing arm is not that abrupt(this is a typical mod,on mono lever bikes)

    love the simplisity and sturdiness of the whole thing

    DAMN!:thumb

    Now, that's an airhead!
    I wish i had the time, tools and talent to build something like that. with maybe a little less suspension (seat height), some slightly more road oriented DS tires, a good seat (maybe that ones not bad) and some aluminum cases that would be my idea of an adventure bike. what i wish the R80 had been.


    Ricky,

    Would you happen to have a higher resolution version of the first pic that you could email me? i would like to print and frame that one for my garage.

    Man that is a cool bike. Very creative.
    That's great inspiration for me to get off my ass and rebuild the R80 that I have in pieces in the basement. But that deal where he has eliminated the electric starter worries me. BMW kick starters are pieces of crap intended for emergency use only. I wonder if he beefed up the tranny to handle it?
    Cheers,

    Where the heck are all of the R80GS Basics that were sold until 98 or 99? South Africa?

    Anyone know of late model R80GS's ?

    I have thought often about doing a distillation of one into a light weight "essential package"

    I'm not likely to do as many monster mods as Eric, but think it wopuild be an awesome project.

    you see Vince,,yeah does bikes are great,but the are all made for people with a lot of money,that don't want ,or don't know how to work on their on bike.

    I think erik bike deserves a lot more merit,,okay maybe not technical but in the passion department is for sure far ahead.

    let try to keep this about hand made bikes BY their owners and not the $40,000 (if not much more money) "Thophy girl's"

    the weber twins comes to mind,,my little golem(in a chessy~wiss kind of way) and a few more but not that many

    Great work Erik. I especially love the alternator/ignition relocation. Makes room for the beautiful exhaust fabrication.

    First, Eric, welcome to the asylum. My compliments on a particularly flashy and appropriate entrance.

    Eric has addressed almost all of the important shortcomings of the airhead GS. It's not the bike I'd build, but it's damn close--a lot closer than what the bavarian hillbillies came up with in the oilhead. Way to go, fella!

    Speaking as someone who kickstarted a /5 for years, and then dealt with a chronically undercharged RS for many more years, and now finds the reliable starter on the KLR very handy in awkward situations...well, I like the magic button. All that said, a good ignition and those Mikunis should go a very long way to making that kick starter work as well as a kicker can. Airhead starting problems stem from the stock ancillaries; nothing in the engine itself should keep'em from lighting right up.

    This is great. I want to see some pics of that bike buck nekkid. Really. I can't tellya how many hours I've spent staring at my old GS, and thinking how I'd chop the front and top off that engine, and move the battery, and build an airbox, and...and...and now Eric's gone and done it. Fabulous.

    some how i was sure you will like it,,,

    Just to prove again that passion goes much farder than money..

    the only way to make bikes like that is to do it your self,even if you have a machinist or a welder do it,is something "Lost in translation"(anybody see that movie is awesome),,stuff like this is a Do it your self paradise.
