A wild new front fairing, new brake components and decoration are the key changes for the range of OTK chassis for 2025.
The OTK Kart Group has announced the 2025 range of Tony Kart, Kosmic, CS55, Exprit, Redspeed and LN Karts.
The Kosmic brand has undergone a complete and striking redesign of the graphics, while all the others have evolved from existing liveries.
From a technical perspective, the 30mm chassis and 32mm chassis for both Direct Drive and Shifter versions are unchanged compared to the previous homologation.
The famous “Hotdog Bun” front fairing from the past few years has gone, replaced with a new “M11” fairing that features turning veins to channel air flow, plus a bizarre-shaped number plate. It will be interesting to see how this is interpreted against Karting Australia’s rules for number plates: “be of a shape that exhibits the characteristics of a rectangle, but it may have some notable variations from a standard rectangle that give the shape a distinctive and unique appearance, with a blend of rectangular and curvilinear elements.“

OTK claim this new piece “improves aerodynamic efficiency, with consequent positive effects on track performance”. Side-pods and rear protection, part of the M10 kit introduced with the previous homologation, remain unchanged.
New brake components feature on the Junior and Senior size chassis. The new systems are named BWD (for the single-speed categories) and BWZ (for Shifters, including including DD2).
For both models there are two options for the rear disc (either 180mm or 206mm) plus redesigned master cylinder and calliper to improve heat dissipation and control brake fluid temperature.
The chassis for the Mini/Rookie/Cadet EVM and EVS versions are unchanged, but they will have new forged aluminium and multi-adjustable pedals, new BMT4 stub axles (with 235 mm steering rods) and new hubs made of magnesium (front and rear).
