what class does the 1125r runs in

[jfboothe]

So out of curiosity (since I have one of each sitting in my garage) would an 1100DS motor out of a Hyper fit in a 749s chassis?

[Gino230]

Yes it will. You will have to enlarge the hole in the engine cases for the swing arm pivot but that's it. There are other ways to do it by modifying the frame, but I think this way is the best as it will preserve the design of the frame to the largest extent possible.


You will have to fab up some exhaust headers. I think on that frame there is enough clearance with the rear shock so there should be no machining of the head. Not sure about the wiring harness.


The bike that Melka rode at the ROC was a 748 frame. They are all pretty similar. I came very close to doing the 749 frame because I also have a 749 that I race in Thunderbike (and starting in May LW F40)

PS the 1100 hyper motor is the best one.....it has the LW timing gears, top ignition pickup, etc. If you want to sell it instead let me know....

I have a really trick 999R, is it a good starting point for the 1100 motor swap Gino?

Ben, remind me again. You're about 5'8" and 145 lbs aren't you?

Approximately, yes.

The Buell 1125 is allowed in Heavyweight Sulersport, Heavyweight Superbike, Supersport; Unlimited Supersport, Superbike, GP, GTO, Supertwins, and if you are old enough Formula 40.
The air cooled Ducati/Bimota/NCR/Pierobon are generally lightweight so a Buell 125 is several steps above in the race classes.
Having read thru  other organizations rulebooks, I don't see any organizations that allows the Ducati air cooled motors in the water cooled frames. Is there a special provision allowing this that is not in rulebook for Superbike or Supersport classes for any organization, something I am overlooking???

Eric - 1125 is legal for HWSS, unless that is a very recent change?

Eric,

Can you please answer are any changes being seriously contemplated for 2014 Lightweight classes? If so, what are the proposals?

Thanks!

I goofed, you are correct.

Since this thread took a left turn back on page 1.  to confirm:  1st year racing, over 40, riding Buell 1125r with aftermarket brake masters, These are the ones I'm thinking about:

SuperTwins
F-40
Superbike Unlimited (what about Heavyweight?)
GT Series GTO
Rookies Cup GTO

Thanks
Thanks

Eric,

Yes on Heavyweight, AF MC will not exclude you from Supersport classes.
