Vortex Kart Racing Engines — New Stock & Blueprinted Race Prep

MR17 tuned Vortex engines, developed under the DRIVEN partnership (formerly Zanella Racing), are built for competitors running USPKS, SKUSA, STARS Nationals, and regional series throughout the USA. Available in New Stock and Blueprinted Race Prep configurations across the Vortex ROK lineup — from Mini ROK to ROK Shifter.

This is a performance-first program for drivers and programs that prioritize results, reliability, and expert support over entry-level price points.

All engines include shipping.

Engine Notes

ROK Mini

The ROK Mini is dedicated to young drivers entering competition. Designed to be safe and approachable, it allows drivers to build confidence and develop technique without unnecessary complexity — while still delivering genuine competitive performance.

ROK VLR

The VLR is engineered around three core principles: reliability, ease of operation, and low maintenance cost. Designed for straightforward inspection and servicing, it is an ideal platform for programs focused on consistent, cost-effective competition.

ROK GP — Limited Availability

The ROK GP has been replaced by the new ROK SV. This is your last opportunity to purchase one of the most proven engines in karting history. The ROK GP Junior immediately established itself on the world stage for its spirited performance, practical structure, and high reliability — engineered to deliver competitive output while maintaining durability across a full season.

ROK Shifter

The ROK Shifter was developed for drivers who want to compete in a gearbox category without sacrificing the core ROK philosophy: stable regulations and controlled costs over time. At 43 HP and 125cc, it delivers serious performance in a platform built for long-term competitive viability.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.
