The TACHO EVO racing kart chassis is the second top line chassis in the Praga product line.

It’s the chassis that won the 2012 World Championship, 2016 Rock Island Grand Prix 125cc Shifter Masters, and continues to perform well with amateurs and professionals alike.

The TACHO EVO STR chassis with Front Braking System and 1050mm wheelbase can be used for any Shifter related motor package. However, it is also well suited for use with other motors such as the IAME X30 TAG, ROTAX or KT100. The TACHO STR chassis is a tried-and-true chassis, having won races around the world including the 2012 World Championship. The frame design is a 30mm tubular frame with a 32mm center crossbar, making it comfortable to drive and great for drivers looking for lateral grip on Sprint tracks and Enduro courses.
