Lightbulb Important information about the 2014 CMRA season opener! (Pg 2)


6.3 CMRA Sprint Series Classes and Regulations
Formula Mini Rules
Formula 4 (No Expert/Novice differentiation)
112cc 2-stroke water-cooled, GP Chassis ok
125cc 2-stroke air-cooled, pre-1995, Motard rules
180cc 4-stroke water-cooled singles, GP chassis ok
250cc 4-stroke air-cooled singles, GP chassis ok
Honda CBR250R, Kawasaki EX250 (Ninja), Honda VTR 250 and Buell Blast using Superstock rules with airbox modifications or individual filters and any bodywork allowed, Kawasaki EX250 allowed to use 17" Kawasaki OEM wheels. Yamaha WR250X and R using Motard rules allowed.
Among the eligible machines are pre-1995 125cc air-cooled dirt bikes (Motard trim OK), GP Chassis 100cc water cooled (RS100), CRF230F, XR250 in GP frame, Aprilia RS125 (street bike) with aftermarket exhaust and carburetor.
The displacement limits have been raised for Formula 4. (2 stroke singles 112cc and 4 stroke singles 180cc) It seems that there was a misconception that the ESS machines that were running in F4 were no longer subject to ESS rules. That was incorrect. ESS machines running in F4 must follow ESS rules.


6.3 CMRA Sprint Series Classes and Regulations
Formula Mini Rules
Grom Challenge (no Expert/Novice differentiation)
Honda Grom allowed using Supersport rules with the following exceptions:
No clip-ons or clubman bars.
No rearsets.
No fuel controllers.
Airbox may be replaced with pod type air filter.
Throttle body may be repositioned.
OEM final drive ratio must be retained.
No aftermarket bodywork, all OEM body panels must remain in place.
Headlight assembly may be removed and replaced with motocross style front
number plate.
Rear number plates are not required.
New Mini Sprint class.


6.5 CMRA Endurance Series Classes and Regulations
A machine may not run in multiple teams or classes concurrently.
We tried this last season and it caused too many issues.


6.5 CMRA Endurance Series Classes and Regulations
CMRA Lightweight Endurance Series Classes
500 Classic
Per 500 Classic Sprint Rules

500 Supersport
Per 500 Supersport sprint rules

300 Supersport
Per 300 Supersport sprint rules

E Superstock
Per E Superstock sprint rules (no Formula 4 machines allowed)

Formula 4
Per CMRA Formula 4 sprint rules (no E Superstock machines allowed)
New Lightweight Endurance Series classes. I need to make it clear that there is no riding up or down in this series. ESS machines are no longer allowed to run down into Formula 4 Endurance.


6.5 CMRA Endurance Series Classes and Regulations
Endurance Rules and Regulations
Oversized fuel tanks are NOT allowed in 300 Supersport and 500 Supersport endurance.


6.5 CMRA Endurance Series Classes and Regulations
Calls to the Grid
Unless otherwise instructed all endurance machines are required to be on the grid or pre-grid no later than 10 minutes before the scheduled start time. Teams will be given a first, second and third call for each class over the track Public Address system and the CMRA control frequency. First call will be given 25 minutes prior to the scheduled start time. Second call will be made 20 minutes prior to the scheduled start time. Third call will be given 15 minutes prior to the scheduled start time (five minutes before all machines must be on the grid). The #5 board will be displayed five minutes before scheduled start time (five minutes after all machines are due on the grid).
Sighting/Warm-Up Lap
When the #5 board is displayed, all generators must be unplugged and removed from the grid. All nonessential team members must also leave the grid. All starting riders should be dressed and ready to go.
When the #4 board is displayed, all machines should be started and tire warmers must be removed. All crew members must clear the grid at this time.
When the #3 board is displayed, the grid will be released one row at a time for their warm up lap. The #3 board will be displayed for one (1) minute then taken down and the pit exit will be closed. Any rider failing to take the warm up lap or that was not present on the pre-grid will, at the Pit Steward's discretion, be sent directly to the grid or held at pit-out until after the race start. Those riders sent directly to the grid will be required to take the first available grid position on the last row of the starting grid. Those starting from pit-out must stay at pit-out until after the race has started and will be held until after the starting field has passed the pit exit. Track configuration and race direction will determine whether riders will be allowed to go directly to the grid or not. Any rider taking a warm-up lap when the #3 board has been taken down will cause the rider to forfeit their grid position and will be assessed a grid infraction penalty. The penalty for grid infraction is listed in Section 7.2.
No practice starts are allowed during the warm-up lap. Riders performing a practice start during the warm-up lap will be moved to the last row of the starting grid.
This is the new pre-grid procedure for endurance starts. Please familiarize yourselves with this procedure.


6.5 CMRA Endurance Series Classes and Regulations
Pit Stops
Refueling must take place after all mechanical interventions on the machine are finished, before the rider tries to restart the machine. Tire warmers must be removed prior to refueling.
All team members other than those directly involved in refueling shall be "behind the wall" or standing and clear of the machine during refueling.


6.5 CMRA Endurance Series Classes and Regulations
Pit Stop Safety Violations
Pit stops will be monitored for safety by CMRA officials. Penalties for safety violations will be assessed by adding the penalty time to the team's overall race time. These penalties are not allowed a protest.
a) crewmember(s) over the wall with improper attire - 30 seconds
b) more than 6 team members (including riders) over the wall during a pit stop - 30 seconds
c) any fueling or any other pit stop safety related violation - 30 seconds
These penalties will be doubled for each repeat offense.
Officials will no longer hold teams on pit road for penalties. The team will be notified of the infraction and time will be added immediately. The upside to this is that if it is determined that the infraction was applied in error the time penalty can be removed.
