What is the difference between the Duraclutch R Series and S Series (Original)

The information below is the OPINION of Hunterworks not of Duraclutch!!

There are several differences between the R and S Series (Original), obviously price is one and two is the primary clutch is the main difference.

The S series is a full on Engine Braking model with more moving parts like the two clutch packs that allow for a super smooth take off with no jerking at all.

The belt stays in constant contact with the sheaves on the S series where as the belt must be engaged with the R series.

The S series uses tradition flyweights and spring where as the R series uses round roller weights and spring much like Yamaha does in the Rhino and newer CVT models.  However unlike the yamaha the belt is not in constant contact and it has a primary spring. The R series round roller weights run in tracks in the clutch and have a cover to protect them from dirt and water.

Driving experience difference?? With the S model, you literally touch the gas and as soon as it gets above idle you start moving, no jerk or belt slipping

With the R series the belt must be engaged, while the engagement experience is much better than the stock clutches, there is the chance of some slight slip and jerk.

The S and R model both have full on engine braking until you stop.

How do you decide which is right for you? 

Pretty simple really, if you need 100% fix for jerky starts and do not mind spending the extra money for those features purchase the Original S series.

If you want to save some money, the possibility of a little jerky start then chose the R series.

Either one is backed by a one year warranty, out of warranty repairs on a primary clutch are far less expensive on the R series than the S.
