"Just a sincere "Thank You" to SMC for an incredible clutch. My son won Jr. Animal Sprint Heavy at Daytona yesterday with the new Roller Lever single disc Vortex. And the best part....we didn't have to touch the clutch the whole week !!! Not one single adjustment was necessary !! This bulletproof clutch let us concentrate on his driving and the chassis. What an amazing piece !!! Thank You !!!"

"Here are a pictures of my daughter Charlotte who won the pre-final and final at our last club race in Ottawa, Ontario Canada last weekend (Sept. 2011). We have been running the dragonskin clutch for 7 years and so does all the club members.

I bought a Vortex clutch (non roller style levers) a couple of years ago but could not fit it on either my kids kart due to it's size and the way we had the seat positioned, would clear the engine or seat, so it sat in the trailer for 3 years. This year we became CRG dealers and Charlotte wanted to try one out. Bolted a new LO 206 Briggs and off to the track we went.
Engine break in fine. Start pouring it on and clutch fails. Stick another Draggonskin on, snap the key way........out of clutches......Let try this thing that's been bouncing around the trailer for a couple of year. To our amazement, we were faster just by bolting the Vortex on. After a half dozen races we realized this thing (the Vortex) is amazing, very little to maintain, easy to set up and change engagement, release and engagement are precise and consistent.

It's been our little speed secret until last weekend when other racers noticed it at tech when Charlotte lined up for a tear-down. Awesome product, reliable, cheap to maintain and fast out of the box.
Thanks SMC."

SMC Vortex Clutches

Vortex - the latest technology in kart racing clutches. The spring is twisted to store energy (similar to a whirlpool or vortex) in order to connect directly to the lever. The clutch responds more quickly at the onset of engine bogging consequently allowing the clutch to remain within 40 rpm of the peak torque value where maximum acceleration occurs. Engagement is very smooth.

SMC Roller Levers

Bully Style and Vortex Style

January 2011 Structure Mechanics Corporation unveiled the new SMC Roller Lever. In short, SMC designed and built bearings that fit between the levers and the pressure plate. The result is much smoother engagement and faster acceleration.

The SMC Roller Levers were secretly raced while data was collected on durability as well as performance. The results were awesome, so we went public. SMC Roller Levers are manufactured for Bully clutches and Vortex clutches.

The new levers are a simple and direct replacement for the old levers. No machine work or special tools are required. Racers do not have to buy new clutches to take advantage of this new technology. All SMC Vortex clutches are shipped with SMC Roller Levers. The old style brass levers are no longer available.
