AKA Tender Document For Future Cadet/Rookie Engine

  10 January 2013

The Australian Karting Association has released the Tender Document for a future engine in the Cadet and Rookie classes.

The intent of the tender is to introduce a new engine into these categories that has parity, is cost effective, light weight, long life and can easily be transitioned from Cadets to Rookies.

A number of the required specifications for the future engine are:

  • Two-stroke
  • Fan or Air Cooled
  • Cast iron cylinder liner with machined ports (AKA has a preference for engines with a non-removable liner)
  • Tuneable diaphragm carburettor with machined venturi and fuel transfer passages
  • Centrifugal Dry Clutch with minimal maintenance
  • Maximum 12,000 RPM (preferabley, this will be governed by the internal engine design)
  • Maximum weight 8kg in Cadet spec (including carburettor, exhaust system & starter system but excluding the engine mount)
  • Pull Start with the facility to be externally started
  • Long life with 20 hours between top end rebuilds and 40 hours between bottom end rebuilds
  • Deliver similar power curves to the Comer SW80 for the Cadets class and the Yamaha J in Rookie trim for the Rookie class
  • Engines are to have exceptional parity.

Interestingly, there is a requirement that the new engine be faster than the current motor (between 1 and 1.5 tenths on a 1000m track). The AKA also stipulate minimum margin between wholesale and retail price on the engine (max RRP of $1,650 inc GST) and spare parts.

Tenders close 5pm Friday 31st May 2013.
