Something new??

I've seen alot of stuff in Forums and searches over the years, but somehow.....this one has slipped by. A Crescent 500cc powered bike!!

Better than that .... its has a sidecar! With the rider's legs going straight out the back it must have been a straightaway record attempt machine

Sam, you spent to much time around boats and not enough around bikes. Just a normal road racing side car, nothing special. In to the early 90's they were stilll running full tilt 500cc two stroke G.P. motors in side cars. Ultra fast. Because of the much larger rear tires, they were able to use more H.P. that the G.P. bikes. More radical port timing and pipes.

BMW had a motorcyle factory in Berlin and Dieter Konig was friends with those guys. In fact, a lot of Dieter's machines for his factory came from BMW when they upgraded. Dieter and Hans Krage both got BMW chassis' and fitted them with Konig outboard motors. Not the stock production motors, but the full race Konigs. Dieter had a 350 in his, but you know Hans. His was a 500cc.

Jimmy Johnson once built a Champ motor into a drag bike for a guy. When the bike racer came to my town to race it, I just had to be there to see it. And it was SO strange to hear a bike fire up and sound JUST LIKE a formula one boat!

Very odd sensation to my ears. :D

Michael, I was baseing my straightaway guess on the fact that the rider and his cowling do not look like he can move around in the normal way sidecar riders do. The top image shows the hack with the bike cowling off, but sidecar cowling on. The sidecar rider's legs are going straight out the back, not the driver's. Looks like the sidecar's cowling would prevent the rider from leaning out his side and there is no handle for the rider to grab when leaning over the driver to add his weight to the rear wheel for accelleration. The power of the Crescent motor would not be enough to give up the ability to move around for cornering. The rider's legs are straight out the back without support. It would be very hard to keep that up on a road course. Still think I haven't looked at enough sidecars?

For others here is a link to some sidecars from the same era sidecar racing bikes (http://www.classic-motorrad.de/wbb2/thread.php?threadid=484&sid=0e2c927ce49cbb1f523e0e0e5f381981)
