Installing the 100% Canadian made - Specialty Motorsports Syncrodrive for the Ski-doo Gen 4 850 is a great way to free up power and lose a large amount of rotational and static weight.

There are many gear ratios to suit your riding style and compliment your build perfectly. All without permanently modifying any OEM parts. All parts are made of lightweight anodized aluminum to not only look good but last with virtually no maintenance.

The belts used are a high quality but affordable 8mm pitch carbon belt. That means no break in and no adjusting for stretch over time.

To find out your current gear ratio take your bottom gear and divide it by the top:

Bottom gear/Top gear = Ratio (63/26=2.42)

Over 2.5 LBS of lost rotational weight
Over 6 LBS of static weight Lost
Available in 12 different gear ratios
No break in period
Direct bolt on without modification takes approx. 3 Hours
