Suspension Upgrades for Vespa Sprint 150

The Sprint 150

Engineered for assertive style and speed. Its distinctive body design and legacy agility demand a suspension system that reinforces high-speed stability and minimizes body roll during aggressive maneuvering.

    The Limits of Stock Suspension

  • Excessive Body Roll: The unique single-sided front suspension and chassis geometry lead to significant body roll and wobble during quick changes in direction or high-speed curves.
  • Vibration and Harshness: Basic damping fails to adequately absorb road imperfections, transferring excessive vibration and harshness to the handlebars and seat during daily use.

    Kingham Tech Engineering Advantage

  • Lateral Support Reinforcement: Front suspension upgrades are designed to reinforce the single-sided link, sharpening cornering precision and enhancing stability at high lean angles.
  • Precision Damping Adjustment: Integrating adjustable compression and rebound, allowing tuners to dial out unwanted harshness while retaining the spirited feel of the Sprint.

    Performance Deficiencies of Stock Unit

  • Excessive Vibration Transfer: Stock suspension lacks sufficient dampening force to absorb high-frequency road input, transferring excessive vibration to the handlebar and footboard.

  • Impact Harshness: Low-quality fluids and basic valving cause impacts from speed bumps and potholes to feel jarring and abrupt, disrupting the otherwise smooth ride.

    Kingham Tech Engineering Advantage

  • Refined Low-Speed Damping: Utilizing specialized valving stacks that are optimized to filter out high-frequency urban chatter and minor road imperfections, delivering a smoother feel.
  • Premium Hydraulic Fluids: Upgrading to high-quality, stable hydraulic fluids that ensure consistent temperature performance and stable damping forces for a quiet, composed ride.

FAQ

How does Kingham Tech address the body roll and instability common to the Vespa chassis?

Our upgrades feature Lateral Support Reinforcement for the unique front link, along with Precision Damping Adjustment to minimize wobble and maintain stability during aggressive maneuvering.

We use a combination of Refined Low-Speed Damping and Premium Hydraulic Fluids. This stack is optimized to filter out high-frequency urban chatter and sharp impacts, delivering a smoother, more composed ride.

Original shocks prioritize cost and comfort for a wide audience. Kingham Tech shocks are engineered for performance, offering greater precision, consistency, and tuning capability beyond the limits of the factory unit.

Do your shocks require professional installation, or can I install them myself?

Our shocks are designed for seamless fitment and direct bolt-on installation. However, for safety and optimal performance, we strongly recommend professional installation and final setup by a certified tuning shop.

We offer three main tracks: Product Distribution, OEM/ODM Solutions (for custom manufacturing), and Strategic Partner Programs (for race teams and technical collaboration).

Please provide the scooter’s VIN (Vehicle Identification Number) and submit your inquiry via the contact form to our engineering team. The engineering team will verify the correct specifications and compatibility to guarantee 100% component fitment.
