Ten seconds saved on every pit stop. One-handed operation. Zero fuel spills. Kart-Cap® replaces the screw cap that's been costing you races with a precision flip-top that locks positive and refuses to leak. Available for Righetti Ridolfi and KG tanks.
Pull to open, push to close. One-handed operation shaves at least 10 seconds off every pit stop. The cheapest seconds you'll buy in karting.
Fuel-resistant seal maintains a positive closure under vibration, heat, and impact. Your tank stays sealed from grid to chequered flag.
Available in two dedicated variants: one for Righetti Ridolfi tanks, one for KG tanks. Direct bolt-on fit for the variant you choose.
Holds firm under racing vibration. Proven across RHPK, AFKC and BPEC endurance championships.
Kart-Cap was designed by a professional engineer with over 20 years of karting experience. After years of losing time in the pits with standard screw caps, dropped caps, fuel spills, and fumbled threads, the decision was made to engineer a proper solution.
Development took two years of prototyping, testing, and refinement on circuit. The result has since been proven in competition for a further two years across multiple championships and endurance series.
This isn't a garage project. It's a precision-engineered product built to the standards you'd expect from a professional racing team.
Race-proven results: Winner of the RHPK and AFKC endurance championships in 2025, multiple podiums and wins in BPEC endurance across 2025 and 2026. Still taking wins in all championships through the 2026 season.
Ten seconds per stop. The cheapest seconds you'll buy all season. A fraction of the cost of chasing the same time through engine upgrades.
Bulk discounts available for orders of 2 or more V2 caps, with savings scaling up to 12% on quantities of 4.
Variants can be mixed. Email us with your requirement and we'll send a custom payment link.
