Ausom Scooter World Upgrades Tier List

Stat upgrades ranked by priority —stamina, speed, stability, and beyond.

Upgrade Priority Ranking

S Tier —Stamina Capacity: First purchase for every player. Doubles effective training and race duration.

A Tier —Speed Boost Level 2: 10% top speed increase. Transformative for Street Races.

A Tier —Deck Stability: Trick accuracy and clean landings.

B Tier —Wheel Grip: Cornering without speed loss.

B Tier —Cruise (Level 10 unlock): Passive stamina regen during cruising.

Low Priority Upgrades

Cosmetic glow effects and minor aesthetic upgrades rank lowest. Delay these until core performance upgrades max out. Premium visual effects do not affect race times or trick scores.

Cost Efficiency Analysis

Stamina Capacity offers the best Cash-to-performance ratio in early game. Speed Boost Level 2 becomes the best investment once stamina supports full race completion. Calculate your Cash income from farming methods before committing to expensive upgrades.

Endgame Upgrade Path

Max stamina, speed, and handling before pursuing Legendary part collection. Endgame players optimize loadouts per track —see Race Build and Advanced Walkthrough.
