Real progress in the Cadet class in 2017

The Cadet class was introduced to South African karting more than 20 years ago and has played a valuable part in introducing young children into the game – some of these are todays main circuit contenders!

The technical specification was long overdue for an overhaul because the Comer engine in recent years has earned a reputation for being unreliable and inconsistent in South Africa and yet in the UK and other countries it is used very successfully. Discussing this problem with other countries quickly showed that we needed to change the gearing but this idea met with a lot of resistance earlier in the year – rule changes during a season are always difficult. Changing to a smaller sprocket and adding an inlet restrictor to everyone's surprize did not slow the lap times - on the contrary faster lap times are now being seen even though the average RPM has been reduced by nearly 1000 revs!

The rule changes, designed to improve safety, reliability and durability (reducing the rpm by more than 10% on average), have also had the effect of reducing performance differences between the engines. Several dads have commented that their “practice” motors are now competitive as well. Beginners are also finding the new set up easier to drive.

The performance and durability of the C50 engine is being closely monitored for the balance of the season to assess if any further changes are required to make this an enjoyable and affordable formula for new-comers to karting.

EMR are now having all new motors blue printed to the same spec, without adding anything to the price. To further promote the class EMR is fitting tyres and completing the package so that the Comer Top kart is available complete and race ready for R 32 900 VAT included, ex Zwartkops. Talk your local dealer.

Talk of new engines being introdueced into Cadet continues - 4-stroke, detuned Maxterino or detuned Micro Rok and others will be evaluated for suitability, price, performance, durability, etc. Despite this there is merit in getting the exisiting Comer C50 running in a state of tune for which it was designed. The previous specification in South Africa was totally unsuitable and can only be likened to trying to drive your car flat out on the highway in second gear, all day and not expecting it to break.
