The rule change meeting is open to all members and will be held to discuss the proposed 2013 rule changes. The members attending this meeting will be encouraged to give input on the changes that should be presented to the MRA board for approval. I would like to have finalized rule changes for the 2013 season in place before the end of the year.

1. DOTs in supersport
2. Combine Modern Vintage O and U as one race or separate waves
and freeze the model year at 2003

4. Change 250 cup to production cup and allow 300s and 400s
5. Change frame and case requirements
6. Allow superchargers and blowers in GP classes
7. Allow reduced engine sizes to meet lower class displacements
8. Change points structure to reflect a 7 round season
9. Allow any type of material to be used in bodywork
10. Delete 5.2.2-S
11. Allow racers to reenter the race after falling down.
12. Eliminate HW classes
13. Eliminate Thunderbike
14. Change VIN number requirements
15. Requirement that you have to complete to Super Street classes
without crashing.
16. Allow Ninja 636 in 600 SS
17. Create a modified 600 class to replace the HW classes
18. Discuss the flags
19. No generators after 10:00PM
Listed below are the rule change suggestions, as drafted by the original author.
1.
Original:
2.2.2 Class Equipment Requirements
G. Only DOT approved tires or non-DOT full rain tires may be used. The original molded tread pattern cannot be modified. Non-DOT slicks and non-DOT intermediate tires are not allowed.
Proposed:
2.2.2 Class Equipment Requirements
G. There are no restrictions on tires. Non-DOT slicks and intermediate tires along with full rains may be used.
2.
Original:
2.5.1 Requirements
Modern Vintage motorcycles must use a frame and engine case 10 years old or older, as determined by manufacturers model year. For 2011, the model year must be 2001 or prior.
Proposed:
2.5.1 Requirements
Modern Vintage motorcycles must use a frame and engine case for a model started in production 10 years or older, as determined by manufacturers model year.
For example for 2013, a Yamaha 2003 R6 model started 10 years ago is legal, also should be legal are the 2004 and 2005, as they are the same model with no updates that are not currently banned from updating the 2003 model to.
Additional proposal to 2.5.1
Ten MODEL YEAR rule - with frame and engine as the sole determinant. Since the forks and everything else are open for swap anyway, who cares...? The '99 thru '02 R6 would be considered a '99 model year. The '03 thru '05 as well as ALL R6S's (regardless of year) are all identical frame and engine, so they would all be considered '03 model year. I use R6 as the example because thats the bike I know...
I would combine the two classes simply into Modern Vintage Open. Currently there are only a handful of bikes in each class and a well ridden 600 could still win the class anyway. If signups warrant, we could run them in two waves as we did in the past. MVO in the front, MVU second wave.
Additionally I would suggest we "freeze" it at 2003 model year for five years and then in 2018 change the rule to a 15 model year rule because the 2005 model year bikes are & 2006 are currently competitive in all of our Modern Classes. This is no longer in the spirit of Modern Vintage imo...
3.
Proposed:
New class suggestion
Formula Main Jet
Only rule - Bikes must have been originally produced carbureted, and STILL be carbureted. Everything else is wide open.
4.
Original:
250 production cup
Proposed:
Revision to 250 Production Cup:
New name "Production Cup"
two waves, two classifications - would run in current 250 production cup slots.
400 & 250
Otherwise same rules.
This is to allow for the coming of the KTM 350 & 390, as well as the new Ninja 300 & 400 - and any other surprise little bike that might appear in the next few years. Honda and Yamaha have little bikes that are hot in other markets.. who knows they just might end up over here.
5.
Original:
Superbike class requirements 2.3.1.A. Frame and engine cases must be from the same production model motorcycle, except for single cylinder motorcycles, which may use any frame.
Proposed:
Frame and engine cases must be from the same production model motorcycle, except for twin and single cylinder motorcycles, which may use any frame.
6.
Original:
Technical requirements 5.2.2.P. Supercharging (including turbo charging and blowers) is not allowed, except in Race of the Rockies.
Proposed: Supercharging (including turbo charging and blowers) is not allowed, except in Grand Prix (section 2.4) classes.
7.
Original:
2.3.1 D Reducing engine size of machines from stock displacement to meet lower class displacement limits is NOT allowed. (e.g., a bike that is a Heavyweight in origin can NOT be re-sized for Middleweight competition.)
Proposed:
Remove section 2.3.1 D

9.
Original:
2.2.2.C.l Construction must be of plastic or fiberglass composites, but not other fiber composites such as carbon or aramid fiber
Proposed: Delete this requirement all together. Modern fiberglass bodywork is as light or lighter than any other material.
10.
Original:
5.2.2-S
Proposed:
Delete 5.2.2-S, since it is the same as 5.2.2-D. Unless, of course, it is twice as important as the rest of the rules in 5.2.2.
Flags and procedures will be discussed
11.
Proposed:
I vote to change/bend the rule that says if any racer falls down during a race you cannot rejoin that race.
This rule would only be for expert racers in the ROR class only, the rider must be able to continue safely & must have an MRA official in some fashion or corner worker visually check out your motorcycle for obvious leaks or damage that would make continuing an issue.
12.
Proposed:
Get rid of the Heavyweight classes altogether.
HW End
HWSS
HWSB
13.
Proposed:
Eliminate Thunderbike
14.
Original:
Change for SuperSport section 2.2 C:
"All motorcycles must display a vehicle identification number on the main frame."
Proposed:
"All motorcycles must display a vehicle identification number on the main frame. Frames without vehicle identification number are allowed only if they are stock production frames without modifications of any type."
_________________
15.
Proposed:
I suggest that there be a rule that states:
In order for a rider to successfully complete a SuperStreet class, that rider may not crash at all during the SuperStreet Event. If the rider crashes during the race, he/she may continue to ride during the remainder of the race, pending tech approval/new rider director approval, but his/her SuperStreet credit towards a provisional novice license is disqualified. In order for a rider to apply for a Novice Race license, they must have completed two SuperStreet Events without crashes in either one.
If the rider crashes during the practice/instruction period then the rider must start in the back of the grid of the Super Street Race regardless of registered grid position pending tech/new rider director approval.
16.
Original: 2.2.3
Proposed:
Suggest change to section 2.2.3 Class displacement and configuration limits.

Change the Ninja 250 Production Cup to the Ninja Cup. Allow the Ninja 300 to compete with the production restrictions and allow the 250's to use pod filters, unrestricted electronics, unlimited suspension, brakes, and unrestricted tires.
17. Proposed: A modified production 600 class

(New)2.3 Modified Production classes(*Current classes starting with 2.3 Superbike will be moved down in rulebook i.e. 2.4 Superbike Classes)
(New)2.3.1 Class Requirements
Modified Production motorcycles shall be limited to those manufactured for street use in the United
States. Such motorcycles must be readily available to the general public from established
manufacturers, distributors and/or dealers. Motorcycles must comply with manufacturers' published
specifications for given models and be fitted with all original equipment. Along with the following
items, all Motorcycle Technical Requirements and Supersport rules shall apply.
1. Modifications introduced by a manufacturer to a basic model configuration subsequent to the
original introduction of the model may be fitted within the limits of normal assembly procedures.
External welding, brazing or machining for this purpose is not permitted.
2. Modification of engine case(s) and/or cylinder castings is prohibited, except for the repair of crash
damage.
3. Internal engine modifications are permitted as long as the class displacement limits are not
exceeded and the stroke is not changed. Internal transmission ratios may not be changed.
4. Clutch lining material and number of plates may be changed.
5. The exhaust system may be repositioned for ground clearance or an aftermarket racing exhaust
may be fitted.
6. The ignition coil, condenser and related wiring and fittings may be changed. Accessory electronic
ignition systems may be used provided they are available to the general public. Generators and
alternators may not be removed and must be in working order (individual part failure during event
weekend exempt). Starter may be removed.
7. Chain and/or sprockets (including sprocket material) may be changed. Ring and pinion assemblies
may be changed.
8. Instruments may be added, removed, or modified.
9. The handlebar type may be changed, but they must mount in the original manner. Handlebars and
tank must have a minimum of one (1) inch clearance at full lock.
10. The seat may be changed. Footrests may be changed (rear sets allowed) or modified.
11. Bodywork is open, providing 5.2 Motorcycle Technical Requirements are followed including use of any
windshield.
12. Aftermarket wheels may be fitted if they are compatible with the original, unmodified brake
components. Rear Sprocket hubs and wheel spacers provided with approved aftermarket wheels
are allowed, unless the swing arm, forks, or brake mounting require modification to accommodate
their use. Slight chamfering of spacers, calipers, caliper mounts, forks, or chain adjusters for the
sole purpose of smooth wheel changing is allowed. Wheel size is open.
13. Stock brake calipers specific to model are required. Stock rear brake rotors may be drilled and/or
machined. Aftermarket rotors replicating o.e.m. diameter may be used. (Ex.: Wave Rotors)
14. Brake lining material may be changed and brake hub assemblies may be drilled for ventilation.
Braided steel brake lines are allowed.
15. Brace tubes and gussets may be added to the frame or swing arm, but no original tubes may be
removed or bent.
16. Rear swing arm may be stiffened and the swing arm pivot may be modified, but the frame may not
be altered, except as provided in #15 above.
17. Carburetors may be up‐dated or backdated to any applicable manufacturers' specifications for
that basic model. Turbo‐charging and/or changes to the basic type of fuel induction (fuel injection
vs. carburetors) are not considered such updating or backdating.
18. Carburetor bodies may not be modified but may be fitted with normally replaceable components
for jetting purposes.
19. Air box may be modified or removed. Air cleaners and intake ducting may be modified, added,
replaced, or removed. Velocity stacks may be fitted.
20. Oil injection pumps may be removed.
21. Brake calipers, discs, and fork tubes may not be exchanged for aftermarket or larger model
assemblies (such as 1000cc front end on a 750cc bike).
22. Tires are open; D.O.T. or racing slicks is permitted.
23. Aftermarket triple clamps made for the specific model of bike may be used. (Stock forks as above
in #21 must be utilized).
