Front wheel drive and two wheel drive on bikes?

[bak189]

6 years ago while in Europe, I had a chance to drive a roadracing sidecar that had been built in Sweden that had 2 wheel drive (rear and front)
also using the Hydr. motor set-up for the front wheel, it was still in development at that time.
It was nothing like a "normal" roadracing sidecar outfit....that's all I can say about it.....it would take some time to get used to.......corner speeds
were faster....top-speed was down due to driving the hydr. pump.......at this point in time I do not know if they ever got it sorted out.....or for that matter if it would be legal for FIM sidecar roadracing.........................................................................

This paragraph plus all the changes to 7.G Streamliner points to the fact that motorcycle streamliners will be treated as cars from now on. Too many similiarites between the two vehicles.

"5.A    SPECIAL CONSTRUCTION CATEGORY
This category is the pinnacle of the straightaway racer's art. It contains three main groups. In the automobile group are the unlimited Streamliners and open-wheeled Lakesters with a 4+ wheel configuration and in the motorcycle group are the streamliner and streamliner sidecar class. These classes allow both blown and un-blown, gas or fuel engines. These are all-out straightaway vehicles with non-stock engine blocks allowed, (with the exception of specific Vintage Engine classes). Innovation is unlimited. Modified production bodies are forbidden. Four-wheel drive is allowed in the automotive group only."

Would cage bar diameters/thickness also be the same??  If so would current bike liners be grandfathered in??

Thanks,

  Don't know yet. I asked that same question to Van B back in October on another thread. So far as I can tell, it is still up-in-the-air.  :| The rules committee was supposed to come to some conclusions by now but I didn't see these concerns addressed in the 2009 rules on the SCTA website. I even asked the question "officially" to the SCTA board.  8-) I THINK the motorcycle streamliner roll cage and frame tube dimensions will remain the same as in the past, but who knows for sure, I sure don't. Maybe Bob could enlighten us on the current thoughts on frame and roll cage dimensions.

There was some work done a few yrs ago by Ian Drysdale  http://home.mira.net/~iwd/2x2x2/tech/222basics.html
I was looking at the potential of doing something along these lines and have talked to Ian about this.
He said initially the steering felt a little odd but once you were used to it much faster and sure footed than rwd.

This is in regards to Terry's questions.............
The tubing Dia. and Wall for M/C liners will stay the same as noted in the 2008 SCTA/BNI rule book (1 1/4 x .090) however, there are some changes regarding construction, this info. is noted on the SCTA site under 2009 rules for streamliners.............................................................

Look for changes in bold print.
