This class will be a points class at all MANUFACTURERS CUP events.
It will be the riders responsibility to monitor his or hers points earnings after every event. All requests for points adjustments must be made in writing to firstname.lastname@example.org within thirty days of the points posting for the event in question on all events EXCEPT the Finals. For the Finals ONLY, all requests for points adjustments, again, must be made in writing to email@example.com and within TEN days of the points being posted. Please understand the Man Cup will strive to keep the points tabulations for all classes accurately and correctly and we do hope by you monitoring your own points earnings that any errors or miscalculations can be corrected in a timely fashion.

ENGINE MANAGEMENT SYSTEMS
Engine management systems (EMS), also known as Engine Control Units (ECU) may be either factory or aftermarket units. Factory ECUs may be swapped from other makes or models of bikes.
MANUFACTURERS CUP tech may, at any time, on any motorcycle in competition, examine the maps, settings, data downloads, or any function of any factory or aftermarket EMS, piggyback or inline fuel injection controller, ignition system, data acquisition system, or any other electronic device on the motorcycle. Tech officials may conduct this examination in any manner, including performing the examination with a team representative as an observer only. It is the responsibility of the competitor to have ready, at all times, the required components to submit to this examination. This can include a laptop or PC, software, passwords, download cables, etc. It is also necessary that the competitor, or someone within the competitor’s team, is knowledgeable in the system being used, and is capable of assisting tech officials in navigating through any and all portions of the software. MANUFACTURERS CUP tech may also impound any component of an ECU or data recording system for further examination either on-site or off-site. Refusal to submit to any examination or failure to supply the required components for examination is grounds for disqualification and/or suspension.
ECUs may not detect and may not be activated by radio transmitters, infrared, laser or sonic devices, or any track position devices or beacons. Also, they may not wirelessly (ie radio, infrared, sonic. etc) transmit or receive information during the run to or from any source.
Any electrical or mechanical device that may be used to activate, adjust, or tune any engine function based upon ride height, track position, front wheel speed, or front suspension conditions, is prohibited. Any sensors, including infrared or ultrasonic, that measure the track Christmas tree or timing system, the track surface, or any structure of the track facilities are prohibited. Any non-contact sensor (sonic, infrared, radar, laser, etc) designed to detect or measure distance, position, or location is prohibited. The use of GPS, locator or position beacons, and locator or position transmitters is prohibited. Third wheel sensors, which is the use of any wheel or rolling device other than the normal front steering or rear drive wheel/tire to measure speed, distance, or track position, is prohibited.
Operational front and rear brakes are mandatory and must be in safe operating condition. Brake lines must be OEM type, braided steel hose or stainless steel line. Braided steel hose is highly recommended. Brake lines are to be routed and mounted properly to insure no contact with moving parts. Carbon fiber brake pads or disks are prohibited.
Wheelie bars are permitted.
All Pro Open entries must have a minimum of 2” ground clearance with rider sitting on bike, straight up perpendicular to ground (oil retention blankets may be removed to pass ground clearance test) All ground clearances are to be measured with the amount of air present in the rear tire at the conclusion of the run. No rider or team member is allowed to alter the pressure, measure the pressure, or otherwise make any contact with either tire valve stem until the conclusion of the post-run technical inspection. If an entrant fails the ground clearance inspection and their rear tire pressure has dropped below 8lbs they will be allowed, upon the tech director’s approval, to raise the rear tire to 8lbs and reattempt the ground clearance test.
All riders must have full leathers (zipped together leathers are recommended and may be mandatory in future). All riders must have a SNELL 95 or higher full-face helmet with shield, leathers gloves, and shoes above the ankle. All motorcycles and riders must pass IHRA safety inspection. Ballistic blankets are recommended but are not required. Tether kill switches required on all entrants. Kill switch, when activated, must disable ignition, fuel pump(s) and nitrous system solenoids.
In order to maintain a level playing field, MANUFACTURERS CUP will monitor the performance numbers of the class. From time to time, it may be necessary to adjust the class rules to retian the spirti and objective of this class. Any rule revisions deemed necessary by MANUFACTURERS CUP would be officially posted on the MANUFACTURERS CUP website a minimum of 14 days prior to the event in which they become effective (the rulebook on the MANUFACTURERS CUP website on the day of the event is in full effect). Any rule revision deemed necessary for the reasons of safety may be made at any time, even after the start of an event, and may be made effective immediately.
There are no weight requirements in Pro Open.
