Polaris 900 RZR - Trail / S / XC

Stock or oversize tires. Adjustable clutch kit. Polaris has replaced the 800 RZR models with a new RZR. This is a new chassis and a new 900 engine version. These new 900 RZR models can come in different forms. Some models have standard (non-EBS) clutches, and some have EBS (Engine Braking System) clutches.

For most of the 50’’ or XC that have LE, or EPS (power steering) distinction have EBS clutches, and the base models, and RZR S do not, but be sure to check your application as the clutches on the vehicle are different. We have built a new custom adjustable flyweight for this application and there are kits for both standard, and EBS clutch systems.

Standard, non-EBS The standard clutch version (non-EBS) of the 900 RZR / RZR S is quite well calibrated from the factory. Testing of the vehicle showed that for most typical trail / mixed use of the vehicle with stock (and most 26- 27’’) tires, the stock clutch calibration was fine and no clutch kit is necessary. For many, that means, save your money. This kit can be used when it is for sand dune use, or to help with power losses from higher elevations that are typically above 4000 ft.

For 27’’ heavy mud type (that measure a full 27’’ tall and are heavy versions) and all 28’’ sizes, this kit is used. The instruction manual has a ‘‘Setup Guide’’ that shows how to set up the kit for your application.

EBS (Engine Brake) version

The EBS versions have different clutches on them. Engine braking is very valuable for some riders, and not necessarily for others. It can be rider preference. The EBS versions were not calibrated as well from the factory, and clutching performance can be improved upon for stock or oversized tires. There are also adjustments to help with power losses from higher elevations. Accurate clutch calibration is important to belt life, performance, and backshifting in load conditions.

The clutch kit for this model not only has the adjustable flyweights and springs, but it also has a new helix included. It is actually 2 helixes! The solid billet helix has 2 different sets of ramp curves machined in it. The helix ramp used for your application depends on tire size and application. Everything is in the instruction manual in the set-up guide. It shows you how to set it for your tires and application, as well as how to change it if you change the tires in the future.
