The perfect platform for the entry-level driver, the ROK VLR not only offers superior performance over its rivals with lower maintenance, but it also offers some great features like electric start all at a cost racers can afford.
The new ROK VLR engine was designed solely with club racers in mind, whether it’s a new racer getting into karting, or for those looking to move up from a four-cycle powerplant. Also, for racers that want to update their current 100cc to a state-of-the-art engine package, this engine covers it all.
The new ROK VLR engine comes complete, ready to race minus the engine mount.
The ROK VLR engine can be utilized in Junior VLR (ages 12-15), Senior VLR (ages 15+) and Masters VLR (ages 32+).Download Engine Fiche Download Manual Download Tillotson Homologation View Engine Statistics Parts Catalog 2023 Technical Regulations
