The new Ø32 mm PRAGA INVICTUS EVO STR Chassis - The Unbeatable Kart

PRAGA INVICTUS offers different solutions for different categories. Satisfying the needs of every driver is our goal.

The INVICTUS chassis with its Ø32 mm tubular frame is ideally suited for larger race drivers running on sprint courses and enduro tracks. The chassis may be used for any Shifter motor applications, however, it is also well suited for use with other motors such as the IAME X30 TAG, ROTAX or KT100. The 1050mm wheelbase and increased rigidity allows the  INVICTUS chassis to perform better in low grip situations.
