The United States Pro Kart Series, presented by MG tires and IAME USA East, has announced a series of Tech Updates for the IAME X30 engine package.

In order to give competitors appropriate time to procure the new parts, as well as use up existing inventory, USPKS Rounds 1 & 2 at the Ocala Gran Prix on March 11-14, 2021 will run under the current USPKS rule set with existing X30 components.  No new parts changes are allowed, that are not in the USPKS Tech Manual.

Changes:

1.  New Exhaust System – Full length one piece pipe with header manifold similar to IAME Swift and KA100 set ups. Junior will be restricted to 22.7mm exhaust manifold.  This will be MANDATORY for X30 Senior, X30 Junior, and X30 Masters beginning with USPKS New Castle event April 30-May 2, 2021.

2.  Simplified Ignition System – Still with 16,000 limiter, this system is more robust and has components with great reliability. This will be ALLOWED FOR COMPETITION AS AN OPTION for X30 Senior, X30 Junior, and X30 Masters beginning with USPKS New Castle event April 30-May 2, 2021.  Previous ignition system will still be allowed for competition.

3.  New Airbox – Modernized appearance with same inlet tube size. This will be ALLOWED FOR COMPETITION AS AN OPTION for X30 Senior, X30 Junior, and X30 Masters beginning with USPKS New Castle event April 30-May 2, 2021.  Previous airbox will still be allowed for competition.

4.  New Roller Main Bearing – New proprietary roller style main bearing will replace the standard 6206 type ball bearing for much greater longevity. This will be ALLOWED FOR COMPETITION AS AN OPTION for X30 Senior, X30 Junior, and X30 Masters beginning with USPKS New Castle event April 30-May 2, 2021.  Previous bearings will still be allowed for competition.

IAME USA East will provide more information on the coming days regarding pricing and availability for purchase of these items through their dealer network.

Because USPKS has maintained such a close relationship with IAME USA East, the series reached out to Eric Jones to provide his thoughts on the changes, and to help everyone better understand why it was necessary.

“As many of you know, the ongoing COVID pandemic has continued to severely impact supply chains across the world and IAME USA was put into a position to move to the current global IAME X30 specifications earlier than anticipated.  With an inadequate supply of the USA spec (2013 and older model) parts into the foreseeable future, this is the only feasible option we had on the table.  Although not ideal in the short term as we understand there is some inconvenience to the changes, this puts us back in line with IAME X30 rules across the world.  With this move, we anticipate another very long period with little to no changes similar to our first seven years with the X30 platform here in North America.  

 We are very proud of our accomplishments with the IAME platform over the last seven years and are also extremely grateful for the support of IAME Spa to help promote karting in the United States.  These are certainly trying times for everyone, but with the recent influx of new karters entering our sport through our facilities over the last six months, it’s become apparent that karting will continue to thrive as a foundation for motorsports and one of the best sports activities that families can be involved in.

 We will be releasing details yet this week regarding the availability of the new components, special introductory pricing on the new exhaust system, as well as preordering information for our IAME dealership network.  In addition, we have been in discussion with several of our promotional partners and they will begin announcing their plans for the implementation of these changes in the coming days.

 Thanks again for your continued support of the IAME program and we look forward to seeing where the future takes us.”
