Collection: Swift Kart Chassis Built in USA for LO206 Racing Performance

Quick Fit Summary for LO206

• Designed around LO206 racing kart power delivery and real race conditions.
• Run successfully across LO206 classes (junior through adult) with proper setup.
• Proven driver weight range: 110 to 220 lbs.
• Recommended driver height range: 4 ft 10 in to 6 ft.
• Wide adjustment range for aggressive to more reserved driving styles.

Tubing selection is focused on material quality and hardness, providing a durable structure that stays compliant enough to work across a wide range of grip levels for LO206 racing.

• Tubing and layout: selected for long-term chassis life with durable, flexible response over changing grip.
• Rear crossbar behavior: promotes lift and allows stiffness to be tuned.
• Axle options: supports 40mm or 50mm, with both hard and soft axle choices.
• Front-end tuning: Ackermann adjustments and ride height tuning available.
• Track width range: approximately 55 inches with a 50mm axle down to 49 inches with a 40mm axle.
• Wheelbase: wheelbase adjustability is planned for 2026 models.

Example baseline direction (starting point)

• Low grip direction: 40mm hard axle, narrow rear width around 49 to 50 inches, front around 47 inches, neutral caster and camber.
• Higher grip direction: soft axle with rear around 50 inches, neutral caster and camber.

Small rear width changes can make meaningful differences. Seat position remains critical, as with most LO206 racing karts.

This LO206 chassis offers a wide, effective tuning range. It can be tightened up or freed up depending on conditions, with the biggest gains typically coming from getting the core fundamentals correct first.

• Highest influence adjustments: seat position, axle selection, width, caster, ride height, and tire pressure.
• Seat position: one of the most influential adjustments, incorrect placement can create major balance issues.
• Small changes matter: width, caster, and tire pressure can cure tightness or free the kart up quickly.
• Forgiveness: responds well to changes, but the outcome depends on using a consistent tuning process.

The Swift Kart LO206 chassis is designed to accommodate a wide range of driver sizes while maintaining proper balance and feel. Correct seat selection and placement are critical to unlocking the chassis’s full performance window.

• Recommended driver height range: approximately 4 ft 10 in to 6 ft.
• Recommended driver weight range: under 220 lbs, with proven success from roughly 110 to 220 lbs.
• Target front weight: approximately 43–44% front when properly configured.
• Seat sizing: M/L, L, and X/L seats commonly work well across this range.

Seat position is one of the most influential adjustments on the kart. Fore and aft placement, seat height, and lateral position directly affect weight distribution, lift, and rotation. Even small errors in seat placement can create major balance issues.

This Swift Kart chassis is built to fit a wide range of LO206 drivers, from junior racers moving up to adult drivers, and it adapts well to aggressive drivers as well as more reserved styles. With wheelbase adjustability planned for future models, the platform continues to expand its fit and tuning window.

• Best fit: medium to adult LO206 racers, with strong support for adult driver ergonomics.
• Also fits: junior drivers depending on seat selection and configuration.
• Best for: racers who value quality, adjustability, and post-purchase support.
