Lightbulb Important information about the 2014 CMRA season opener! (Pg 1)

January 23, 2014

To All CMRA Members:

Important information about the 2014 CMRA season opener.

1) To avoid long lines pre-enter for the season opener! The deadline for pre-entry and advance licensing is midnight, Thursday February 6th. All pre-registration forms are available on the Forms Page of the CMRA website. For licensing or pre-entry questions, contact Nancy Selleck @ 817-570-9779 or

Technical Inspection
1) Your machine needs to be ready to race when you bring it to Tech. Lower fairings must be removed but must accompany the machine to Tech.
2) Have your paperwork in order. Bring your registration receipts with you. Have your Tech verification forms filled out completely including the VIN#. All contingency forms must be filled out completely and legibly and turned in at Tech when the machine comes through.
3) All items requiring safety wire must be wired and all old 2013 Tech stickers must be removed.
4) All machines must have numbers installed before coming through Tech. We'll be checking your number plate placement and clarity at this time. PLEASE MAKE SURE YOUR NUMBER PLATES ARE CLEAR AND PLACED CORRECTLY!! I've noticed a few pictures posted on various message boards of bikes with numbers that will not pass Tech. Numbers with a thin outline of white or yellow shadowing the numbers that is intended to be the background is not allowed. No serifs on number ones. Yellow and white are the only number plate backgrounds allowed. Numbers and number plate guidelines can be found in the 2014 CMRA Rulebook. We understand that some machines are very difficult to fit with number plates so please feel free to contact me directly for assistance. Walter Walker (254) 644-9393 or

Major Class Structure and Rule Changes Explained

3.12 Transponders
CMRA requires that riders have a charged and properly functioning AMB transponder securely mounted to their machine whenever they are on the track for any purpose, including practice sessions.
A rider participating in a practice session without a properly functioning transponder may be shown the meatball flag and required to report to the Steward at pit-in immediately.
This should be self-explanatory but just in case it's not, charge your transponders before you get to the track and put it on the bike before you go out on the track! Endurance team back-up bikes are the only exception to this requirement for practice only.


5.2 Motorcycle Requirements
e) All machines must be equipped with a front brake lever guard.
Again self-explanatory. I want to add that whatever brand or model Brake Lever Guard is used it must be mounted properly so that it does not move or interfere with the brake lever operation. I would also recommend that you have a spare on hand in the event your lever guard is damaged or lost in a crash. This item will be inspected in Tech and will be re-inspected during a re-tech after a crash.


6.2 CMRA Sprint Series Categories
Supersport is limited to U.S. market EPA and DOT approved versions of the specific machine brands and models designated for the class in Section 6.3 - CMRA Sprint Series Classes and Regulations.
Following is a list of the only things which should or may be done to a Supersport machine:
a) The OEM wiring harness shall not be modified or replaced; removal of items allowed in this section which connect to the harness must be accomplished by un-plugging at an OEM connector; if allowed removal of an item results in an interlock that is not suitable for racing, the interlock over-ride must be accomplished by plugging jumpers or other required items into the remaining un-modified harness connectors.
b) The OEM frame, subframe(s), fairing stays and all mounting hardware and brackets shall not be modified; any bracket or hardware which supports only an item which may be removed may also be removed; any bracket or hardware which supports an item which may not be removed in addition to an item which may be removed, must remain on the machine un-modified.
c) Passenger pegs, grab rails, horns, mirrors, turn signals, tail lights and housings, headlights and housings and reflectors may be removed.
d) Aftermarket rearsets, clip-ons or handlebars and levers allowed; lever guards allowed.
e) Aftermarket exhaust allowed.
f) Aftermarket ECM controlling fuel mapping and ignition timing only allowed; quick-shifters, ignition cuts, traction control not allowed.
g) Aftermarket rear shock and fork internals allowed. Revalving of OEM shock and forks is allowed
h) Aftermarket brake pads and lines allowed.
i) Aftermarket chains and aftermarket sprockets with any gearing allowed.
j) Aftermarket bodywork allowed only if it exactly replicates the size and shape of the OEM bodywork with the following exceptions: solo tail allowed; openings for headlight, taillight and turn signal may be covered or filled-in. OEM bodywork stays and mounts must be used. Alternative bodywork fasteners may be used (e.g., DZUS fasteners).
k) Aftermarket filters of OEM type allowed (a K&N style direct replacement air filter is an acceptable OEM type).
l) DOT-approved tires with an S or higher speed rating must be used and the original tread pattern cannot be grooved or modified; slicks may not be used; rain tires can only be used if the event is declared wet by the Director of Competition; non-DOT-approved rain tires may be used with no modification of their original molded tread pattern.
The items above constitute the entire realm of deviation from showroom stock for Supersport classes. If it does not mention you CAN do it, then you CAN NOT.
This defines the allowed modifications for our new Supersport classes. (300 and 500 Supersport) It has been noted that the sidestand bracket and the license plate/rear fender bracket may be removed from the CBR's frame/subframe if needed. These are the only items that may be CUT off of the CBR's frame/subframe.

The following allowance has been approved for Supersport machines. A Technical bulletin will be issued to include this allowance in the 2014 rulebook.

Brake rotors may be changed to "wave" or "petal" type rotors of the same material and maximum
diameter as the OEM rotors. No carbon fiber, cast iron or other exotic materials are permitted for
brake rotors unless stock. No oversized rotors.


6.2 CMRA Sprint Series Categories
l) -----Master cylinders may be replaced with any OEM master cylinder regardless of type from any make or model. Aftermarket master cylinders are allowed but are restricted to same type and as close as possible to the OEM bore and stroke.
