Roger Goldammer ExperiMental Bike.

All reputable custom motorcycle designers and builders will tell you the same thing. Even when they build a bike commissioned by a client, they build the bike that they dream of. Simply because they are the designers and builders, not the client. Too much restrictions and control from a client and the bike will never be as good as it could be and should be.  Roger Goldammer doesn’t build commissioned bikes anymore.  He now designs customs to live up to his own taste, specifications and standards, and try financing his projects through the sales of his parts line. “ExperiMental” (notice the capital M in the name) the bike he built for a TV episode of Discovery channel Biker Build-Off, is a good example of what a great builder can do when he has no limitations placed front of him. “ExperiMental" is a two-stroke BRC 250cc super kart motor placed in a heavily modified Honda dirt bike frame. It’s an Aprilia Rotax designed Tandem-Twin, two cylinders, one in front of the other, and two crankshafts geared together. It features an electric water pump, ceramic composite brakes, and even carbon fiber wheels. It was built to dual out against Matt Hotch on the salt at the legendary Bonneville Speedway. On this unusual machine, Goldammer was able to wind out "ExperiMental" to 128.774 mph through the timed mile, besting rival on the salt and fellow builder Matt Hotch on his beautiful custom Vincent (Hotch’s bike was clocked out at 99.728 mph, which is also exceptional). ExperiMental is probably the most efficient dirt bike ever built. Roger Goldammer Cycle Works.

Last Minute Update 04/24/07.. Just talked to Roger. He told me the following: " I guess I must have got some salt in my blood because I am building another HD based machine that I plan to race at Bonneville before it ever sees a bike show, which I will do as well. I just want to meld the custom world and the performance world a little closer together"

    I rode a lot of dirt bikes. Would like to slide this one on the salt.

    Beautiful work….. custom powertrains are now the hot item, very cool choice.

    How are those composite brakes working out? Seems like a great idea, I undertand service life is greatly extended, but I really have seen much press about them.

    “…meld the custom world and the performance world a little closer togethe…”

    Certainly different than the (OCC, et al) streatch customs of late.
    But not new.
    Street/drag bikes were not uncommon in the 60s.

    Up in the NorCal Bay area, Drag-bars were every bit as popular as Ape-hangers and actually more popular toward the end of the 1960’s.

    I’m ready for a change, bring it on……!
