Official Statement From IAME USA Regarding Future of Platform Updates Beginning in 2021 Season

As many may remember, with the reconfiguration of the IAME distribution in North America in 2014, we put forth a commitment to freeze the engine configuration for seven years. This coming 2020 racing season will be our seventh year, and we would like to introduce some of the developments we have in the pipeline for subsequent years.

Before doing so, we want to outline the impetus for any such changes. As we pledged in 2014, safety and customer satisfaction remain our guiding principles at IAME. Any new ideas are in the interest of those two facets, and we are providing notice a year in advance for changes that will take effect on January 1st, 2021.

The new changes we will be implementing are as follows:

1. X30 - New Exhaust System (All Classes) 
   1. Beginning in 2021, SKUSA will adopt a one-piece exhaust similar to the KA and Mini Swift systems. The header will be a fully machined version and offer more reliable restriction for junior X30 classes.
      
      The juniors will use a 22.0mm header which is smaller than the current 26mm but since the positioning is closer to the engine, the sizing is re-adjusted so as to offer a similar performance to the older model.
2. X30 - New Ignition System 
   1. Beginning in 2021, SKUSA will begin using a new ignition system. The main change is a performance restriction at 16,000 RPMs which is the same as the “Digital K” unit. The other obvious features of this system are less wires and external componentry with an improved start button. Both old and new systems will be allowed in competition.
3. X30 – New Main Bearings 
   1. Beginning 2021, a new proprietary long life roller bearing will be incorporated into the X30 model. This new unit will be approved for both old and new engines, but can only be utilized if the crankshaft is not worn past the defined installation tolerances. Both the old and new style bearings will be approved.
4. X30 – New Airbox 
   1. In 2021, we will begin introducing a new airbox. It will have the same size inlet tubes and mainly be an aesthetic and modernized update. Both old and new airboxes will be legal for competition.
5. Mini Swift, KA100, and 175 SSE – No Changes

As stated above, these changes will not take effect until 2021. At which time, we will also reintroduce another configuration freeze for three more racing seasons. We seek to answer and address any questions or concerns regarding the above. We invite anyone with concerns to contact Lynn Haddock, director of IAME competition.
