We don’t want to sound over the top here, however, we have to give it up to Ski-Doo for taking the snowmobile industry in a new CVT direction.
The revolutionary P-Drive primary uses rollers on the spider fingers to transfer power to the torque towers and onto the moveable sheave.
No informed snowmobile clutch wizard is truly content with the current, industry wide sliding button system used to transfer power to the moveable sheave.
Inherent friction and wear causes myriad problems and compromises performance, particularly as horsepower numbers rise. The P-Drive roller principle is 100-percent sound and the execution appears excellent.
We can attest to the tangible improvement in primary clutch shift response under every load condition we encountered.
Simply put, the competition will ultimately copy this technology.
