SUSPENSION Rear Suspension AdjustmentsXTRA 12 Style The primary rear suspension adjustments are the front track spring preload and the rear torsion spring preloadIt is important to note that adjusting the limiter strap does not change weight transfer from the rear suspension to the skis as in conventional suspensionInstead it will increase the entire rear suspension preload and decrease travelTo increase ski pressure the front rear scissor stop (FRSS) should be set to lowTo decrease ski pressure the FRSS should be set to highTo properly adjust the rear suspension, start with the lightest preload setting that will prevent heavy bottomingRemember: adjustments should be made to one area at time, in order to properly evaluate the changeNOTE: Rear spring settings will affect ski-to-ground pressureIf ski pressure is too light it may be desirable to tighten rear springs for an increase in ski-to-ground pressureIt is also possible to reposition the FRSS for increased ski pressure
