ROTAX EVO ENGINES TO DEBUT AT PRO TOUR ROUND 4

Further Information On The Introduction Of Rotax Evo Engines
Karting Australia (KA) and International Karting Distributors (IKD) have finalised and released the Homologation Documents for the Rotax EVO Engines. These documents can be viewed by clicking here.

The new EVO engines will be used in their first competition – Round 4 of the Rotax Pro Tour (Warwick) this weekend.

As advised previously, the introduction of the Rotax EVO Engines will be separated into two distinct categories:

Engines that are to be used in all Rotax Pro Tour National Series Competition Classes; and
Engines that are to be used in non-Rotax Pro Tour Competition Classes including; KA TaG, Tag 125, Restricted 125, Junior Max, Rotax 125 and DD2.

Rotax Pro Tour Events

Rotax World Rules (that are included in each homologation document as the Technical Specifications) as approved by KA for Australia will apply to these events commencing at Rotax Pro Tour Round 4.
EVO Engines will be permitted to be used in accordance with the homologation of these engines.
Previously homologated Junior Max, Rotax 125 and DD2 engines will remain eligible for competition in Rotax Pro Tour events. These engines can be upgraded at any time using the EVO Performance Components. If any of the EVO Performance Components are used on the Engine, all of the Performance Components must be used.
There will be no parity adjustments to equalize the EVO Engines and the Older Engines for Rotax Pro Tour events.

Non Rotax Pro Tour Events

The introduction of “FULL EVO Engines”, “Upgraded TO EVO Engines” and “Performance Components” into non Rotax Pro Tour Competition has been delayed and will take place following further evaluation by KA. EVO Engines and EVO Performance Components will only be permitted to be used in a controlled fashion that ensures appropriate performance parity between the various engines as follows:
– Full EVO Engines to Older EVO Engines;
– Older Engines that have been wholly or partially upgraded to EVO Engine specification by the addition of any of the Performance Components; and
– All Rotax Engines to other homologated TaG 125 and Restricted 125 engines.
An Older Engine can be partially upgraded to EVO Engine specification by the use of any of the Performance Components. Once one of the Performance Components has been fitted, the Older Engine will be classified as an EVO Engine, however, it is not a requirement that all Performance Components are fitted.
An Older Engine will be permitted to use the EVO Exhaust System, EVO Exhaust Socket, EVO Conrod, EVO Crankshaft, EVO Piston and EVO Battery Holding Unit and Switches without being classified as an EVO Engine as these items not designated by Rotax to be Performance Components.

EVO Performance Components
All components determined by Rotax as “Performance Components” are external only. These components are:

Carburettor “VHSB 34 XS”
Dellorto Ignition System with Electronic Box
Electronic Power Valve Assembly
