IAME Cadet Fiche Correction
Please note that following the recently advised introduction of a new exhaust restrictor in the IAME Cadet class, a further amendment to the fiche has been added, which corrects a small piece of information on the exhaust restrictor detail. Following a manufacturing process change, the parallel length of the 16mm restrictor orifice has been decreased from 2.5mm min. to 1mm min. Full details are found in Appendix 10 of the IAME Gazelle fiche in the ‘Technical: Kart’ section of the Resource Centre on the Motorsport UK website at: https://www.motorsportuk.org/resource-centre/
Rotax MiniMax Weight Change
The minimum class weight and the minimum driver weight for the Rotax MiniMax class have been amended for 2021 with immediate effect. The new weights are:
Minimum class weight: 132kg Minimum driver weight: 37.5kg
The full amendment detailing these changes can be found in the ‘Technical: Kart’ section of the Resource Centre on the Motorsport UK website at: https://www.motorsportuk.org/resource-centre/
Rotax Exhaust Gas Temperature Sensor
For 2021 the regulations for all Rotax classes were updated to allow the fitting of an exhaust gas temperature sensor on the exhaust system, however due to an oversight the data-logging regulations in each class were not updated to allow the use of an EGT sensor.
To correct this, an amendment has now been issued to cover each class, which adds an allowance for the collection of data from the EGT sensor. The full amendment detailing these changes can be found in the ‘Technical: Kart’ section of the Resource Centre on the Motorsport UK website at: https://www.motorsportuk.org/resource-centre/
