ST2 Premium Kit

PREMIUM ST2 KIT – Complete Conversion Kit with Vortex ROK VLR Engine

The ST2 Premium Kit is the most complete solution for transforming your Tillotson T4 kart into the new ST2 – Simple, Stock, 2 Stroke configuration.

At the heart of the kit is the Vortex ROK VLR 100cc 2-stroke engine, capable of producing around 20 HP and reaching 15,000 rpm, delivering high performance, plenty of fun, and low running costs.

With the Premium Kit, you can build a setup identical to the ST2 kart presented and used during the 2026 ROK Superfinal, the event that marked the project's official debut.

Accessories included in the kit:

• 1x ST2 axle
• 1x ST2 chain guard
• 1x ST2 chain guard bracket kit
• 1x Starter battery
• 1x Battery charger
• 1x Reinforced chain
• 1x RK sprocket
• 1x Anti-vibration engine stop bolt
• 1x Internal air filter foam
• 1x ST2 sticker kit
• 1x ST2 floor tray sticker
• 1x ST2 rear bumper sticker kit
• 1x KG 509 front fairing panel
• 1x KG 509 spoiler
• 1x KG 509 bracket kit
• 1x KG 509 pin and clip kit
• 1x New Vortex ROK VLR 100cc engine
• 1x ST2 engine plate
• 1x Battery support (included with the engine)
• 1x Vortex wiring harness (included with the engine)

KG 509 bodywork and ST2 graphics: an extra advantage

Compared to the Trophy Kit, the Premium Kit also includes the KG 509 bodywork and official ST2 graphics, completing the kart's transformation both aesthetically and aerodynamically.

The KG 509 bodywork helps improve the kart's aerodynamic profile, offering a more modern, performance-oriented setup.

KG 509 bodywork and ST2 stickers are not mandatory for participating in the ST2 Championship, but their use will be allowed under the regulations.

You can therefore freely choose whether to keep the bodywork already fitted to your Tillotson T4 or use the one included in the Premium Kit.

The same setup as the ROK Superfinal debut

With the Premium Kit, you can convert your Tillotson T4 into the same configuration used for the launch of the ST2 project during the 2026 ROK Superfinal in Lonato.

A solution designed for those who want the most from their conversion, combining performance, aerodynamics, and racing style.

The advantage of owning your own engine

The Vortex ROK VLR engine included in the Premium Kit allows you to train freely, get familiar with 2-stroke performance, and make the most of your testing days on track.

MP Kart Shop also offers the possibility to rent the Vortex ROK VLR engine for individual test and training days.

Important information

The Premium Kit includes a new Vortex ROK VLR engine and all the components listed for converting the Tillotson T4 chassis.

For official ST2 competitions, engines are assigned by draw and managed by the organization, ensuring maximum technical equality among participants.

The engine purchased with the Premium Kit is therefore intended mainly for training, testing, and private track use.
