Vortex Mini ROK Class Information

All basic engine specifications and dimensions will be found in the Mini ROK pdf – including the Supplementary Info pages included - as published in the Rulebook section of this website.  The intent of the class is to run the engine as produced.  The specifications are available to determine any modifications, not to allow blueprinting.  No deviation from the “as produced” engine is allowed. All components must remain OEM.  In addition, there is now a Mini ROK Air Filter that is mandatory for all SKUSA competition. This new filter is RLV part #0204, and can be purchased thru your local RLV dealer or thru the SKUSA online store


Spec Tires

For all classes except TaG Cadet, Race Tires are defined as the two (2) sets of tires purchased from SKUSA as part of the entry process and delivered at the event – one set for EACH race day. For the TaG Cadet class, Race Tires are the one (1) set of tires purchased from SKUSA as part of the entry process and delivered at the event (to be used for both race days). Race Tires will be scanned and assigned to the specific driver -- and are signed out to the participant at the event Tire Desk.

For all classes except TaG Cadet, the MG White Type “MG-SK” is the spec Race Tire and the only slick that can be used in qualifying, heats, LCQ’s and mains.  For the TaG Cadet class, the MG Red Type “MG-HZ” is the spec Race Tire and the only slick that can be in all competition sessions. If rain tires are necessary, they must be the MG-WT (or MG-WZ) rain tires only. Rain tires may be purchased by any available vendor, but if ordering from SKUSA, your order must be received prior to the pre-entry deadline of Sunday, July 27th.

Race Tires are NOT included in your entry fee; however, their purchase is mandatory WITH your entry registration.  SKUSA is the official tire provider for the Pro Tour, and two (2) sets of Race Tires (MG-SK’s) per entry -- or one (1) set of MG-HZ’s Race Tires (for Cadets) -- must be purchased from SKUSA for delivery at the event. 

Tires used in all practice and warm-up sessions must also be the spec MG tires (MG-SK’s for all classes except Cadet; MG-HZ’s for Cadets). Practice tires may be purchased by any available vendor; however, if ordering from SKUSA, your order must be received prior to the pre-entry deadline of Sunday, July 27th.

The Tire Desk will open and close during the event per the published schedule. Competitors are required to pick up their Race Tires (slicks), and any practice or rain tires purchased from SKUSA during these time periods.  Any tire issues occurring after Tire Desk closure should be reported to the SKUSA Registration Desk, and will be handled on a case by case basis.

Spec Fuel/Oil

The SKUSA spec oil for all competitors is Motul 2T Grand Prix. The SKUSA spec fuel is VP MS98. Race fuel and oil is not included in your entry fee; however, one (1) order of each is mandatory WITH your Pro Tour entry registration. NOTE: Additional spec fuel and oil is available for purchase from SKUSA, but must be purchased prior to the pre-entry deadline of Sunday, July 27th. SKUSA may have limited amounts of spec fuel and oil for purchase on site, although it is highly recommended that all fuel and oil be pre-ordered to guarantee sufficient quantity on hand.

Pre-Tech Certification

SKUSA employs a self-certification form to facilitate pre-tech inspection, and TWO will be included in the driver’s registration packet at the track -- ONE for each race day. The driver completes and signs the form to certify that the listed items are in compliance. The form is then submitted on the grid at qualifying (or at the next competition session, if the driver does not participate in qualifying). Drivers are not allowed out for qualifying without turning in an executed pre-tech form. Spot checks of safety items will be made throughout the event and violations may result in penalty assessments. Click Here to download Pre-Tech Form.

Engine Changes

See section of the SKUSA 2014 Rulebook, along with the additional clarifications below:
  1. The engine seal number (received in Registration) shall be entered by each driver on the Pre-Tech Certification form that is turned in prior to the first competition session (i.e., qualifying), and installed on the kart as instructed. This seal must remain in place for the duration of the event. See the event Technical Director for additional assistance.
  2. Engines and/or components will be "painted" by the event technical staff at the post qualifying weigh-in.
  3. Event technical staff may inspect an engine's seal dnd/or "paint" at any time during the event.
  4. Any engine change subsequent to qualifying MUST be pre-approved by the event Tech Director and if not, will result in a DQ and loss of points for ALL prior race sessions and a last place start in the next race session.
  5. It is solely the driver's responsibility to solicit and receive an engine change approval form from and executed by the event Tech Director. It is also the driver’s responsibility to demonstrate engine damage in order to get Tech Director approval to change engines. If the competitor is unable to demonstrate damage, one additional engine (total of 2) may be approved by the event Technical Director. If approved, the competitor will start the next competition session at the back of the lineup.
  6. For TaG classes only, a competitor must declare an engine brand at their first competition session. For the rest of the series, only one engine brand change is allowed.  Note: Should a competitor not declare an engine brand explicitly, the engine brand used in their first competition session will be deemed an implicit declaration.
