Are there any restrictions on offset triples, forks, fork cartridges or brake calipers/MC in Thunderbike? Looking at the 2013 rulebook I don't see anything that prohibits it and I am guessing it is acceptable. However I don't see anything that allows it like it does for the swingarm and rear shock. Thanks for the help.
 
6.4.2. All machines must meet the equipment standards of Section 5, as wellas the following:
A. Frame, cylinder head(s) and engine cases must be from the same
production model motorcycle. Single cylinder motorcycles may use
any frame and engine.
B. The frame must be as originally supplied by the manufacturer on the
approved model. Strengthening gussets or tubes may be added.
Only brackets or tubes not supporting suspension, engine, or drive
line components may be removed. Swing arms may be modified or
replaced and rear shocks may be replaced or relocated. Single
cylinder motorcycles are excluded from this restriction.
C. Reducing engine size of machines from stock displacement to meet
Thunderbike class displacement limits is not allowed.
D. Fairings that meet the requirements of Section 5 may be used.
E. Liquid cooling is not allowed unless original equipment on the model
being used.
F. Original type of induction system must be retained. If a machine
originally was sold with fuel injection, then it must remain fuelinjected. If the machine originally came with carburetors, then it must
use carburetors, however they need not be the original type or size.

Ok. A more thorough internet search and I think I have been able to answer my own questions. Those modifications are legal for thunderbike. If I am wrong, please let me know.

Unless it says you can't do it,  it's legal.
