som skall hjälpa till att bibehålla geometrin under hela fjädringsrörelsen för att undvika att maskinen känns orolig i framvagnen under vissa förhållanden.
Nu har BRP knyckt konceptet och förlängt övre A-armens infästning ute på styrspindeln.
Detta har testats under delar av cross säsongen 2012 och kommer nu på alla Ski-Doo RS-600 ( 2013 ).
Förmodligen en liten mod som även funkar kalas bra på Lynx REX chassi.

"There’s interesting news coming from Ski-Doo.
Plus, we think some of the changes to Ski-Doo’s race sled could end up on future trail sleds.
It’s most notable update comes in the front suspension,
where a new upper A-arm with a taller spindle,
spacer insert and revised ball joint should create less bump-steer and easier turn-in,
according to Ski-Doo Race Coordinator Tom Lawrence.
We first spotted the design of this front suspension on some Pro Open Ski-Doo sleds last winter, first on the Schuering Speed Sport sleds at the ISOC Canterbury Snocross and then on both the Schuering and Warnert Racing race sleds at the Eagle River Derby, where the teams were running varying sizes of spacers to lift the upper A-arm and create the effect of a taller spindle.
Tom Lawrence confirmed variations of the system were tested throughout the season.
Visually, the changes to Ski-Doo’s front end create a large gap between the A-arms and make it look somewhat similar to what Arctic Cat has been using on its race sled for several years –
and what Arctic Cat introduced on its consumer sleds with the Arctic Race Suspension for 2012."

Notice the spacer at top the spindle that raises the mounting point of the upper A-arm."
