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

Modern Technology: Vortex Clutches

Vortex Clutches Are Faster

• Vortex torsion springs are attached directly to the SMC Roller Levers for mechanical efficiency and consequently shorter slip time. Less energy is lost to clutch heating leaving more energy for acceleration.
• Engine bogging or “drop off” has been eliminated.
• Very smooth engagement, particularly important in turns where smooth kart control saves valuable lap time.
• Vortex torsion springs are more precise than conventional compression springs and consequently prevent clutch chatter.
• Fast, durable and consistent, even for heavy karts with road racing gear ratios and standing starts.
• The aluminum drum dissipates heat five times faster than steel.

Race Proven

• SMC clutches have powered winners in every major dirt, sprint and enduro race across the USA.
