The SR30.1 ~ 2019's Twister

The Top Kart SR30.1 chassis (formerly Twister) is the premier kart racing chassis for all engine applications. The 30mm chassis allows the flexibility to be run with lower horsepower engines (Yamaha/KA100) as well as higher horsepower engines (IAME Leopard, IAME X30, and Rotax) for the Junior and Senior applications. Easily adaptable to all varieties of driving styles, the SR30.1 is the ultimate out-of-the-box half second you have been looking for to gain that competitive edge. The SR30.1 is fast and easy to tune for both beginners and veteran racers and will allow you to storm past the competition.

So what's in a name?  The Twister of previous years has become the SR30.1 in 2019.  Next year and in subsequent years, the chassis will be renamed so that you, the consumer, will always know when Top Kart produced the chassis that you are putting on the podium.
