April 2012 - Spring Nationals of the
Midwest Chase'n Race'n ProKart Tour
Winfield, KS.

"I qualified 19th for the Pro Animal feature paying $1000 to win. In the 20 lap feature, I passed 18 karts with the help of only one caution to take the win. I was on a 2007 Phantom Icon racing everyone else on 2012 Tritons, Impulses, and other karts. I was using a two disc Vortex Roller Lever clutch. I ran Animal 340 and Animal 375 also that day. I won Animal 340 and placed 6th in Animal 375."

"The clutch performs perfectly race after race. Running an eighteen tooth sprocket really works the clutch hard but the engagement was always smooth. Even after a bunch of caution laps it never overheated. It's nice to know I don't have to worry about the clutch chattering or slipping unlike others I have had in the past. After making the switch to a two disc Vortex Roller Lever clutch I won't ever change again. It's simple to work on and setting the engagement can easily be done at the track with common tools and no guess work. Thanks SMC for a great clutch to put my Faster Motors power down!"

Thanks, Branden Zinser

About the Vortex Clutches

Vortex Clutches Are Modern

Vortex clutch patents were issued in 2001 and 2003. Every other disc clutch in kart racing uses a design from the last millennium - 1978! VORTEX CUTCHES ARE UNIQUE

• Exhibit hard "pull" instead of hard "hit".
• The only disc clutch with springs attached directly to the levers.
• The only disc clutch without a pressure plate.
• Rebuilds are inexpensive and simple.
• Rebuilds are accomplished in approximately five minutes!

Vortex Clutches Are Faster

• Engine bogging or “drop off” is nearly eliminated.
• Less energy lost to clutch heating leaving more energy for acceleration.
• Very smooth engagement, particularly in turns, permits smooth steering response and saves valuable lap time.

Vortex Clutches Are User Friendly

• Vortex clutch springs are adjusted quickly, easily and precisely without dial calipers.
• Air gap is not an issue with the Vortex clutch, reducing the amount of adjustments.
• The clutch can be rebuilt in a matter of minutes using only a T-handle wrench.
• The parts come in kits allowing you to stock your tool box ahead of time.

Race Proven

SMC Vortex clutches have been used to win every major dirt, sprint and endurance race in the USA. Even for heavy karts with road racing gear ratio and standing starts, it is fast, durable and consistent. Credit goes to the Vortex spring’s simplicity, the efficient heat dissipation of an aluminum cover and superior friction materials.
