Developed for the 2022 IFMAR World Championship with direct input and test information gathered by Infinity team drivers. Major spare parts and optional parts are the same as IF14-2.
The rear section has been moved forward by approximately 1.2mm from the original IF14-2. This change in wheelbase and weight balance allows for faster cornering speeds and improved drivability.
Newly designed PRS aluminum C-hub (minus 2deg caster angle) improves traction and corner speed.
The newly designed USP2 shock is 2mm shorter in overall length than the conventional USP shock. Plastic parts, pistons, and other parts are identical to those of the USP shocks, maintaining the commonality of spare parts.
New shock spring for use with the new USP2 shock is the newly developed SMJ Stealth Line Spring. The material and manufacturing process of the conventional SMJ Stealth Line springs have been revised to achieve a more smooth initial movement in the early stages of roll.
New aluminum rear wheel axles are 1.5g lighter per axle than the standard steel ones, contributing to optimized front-rear weight balance when PRS is used. These lighter axles also improve throttle response. Both the aluminum driveshafts and aluminum rear wheel axles are hard anodized to dramatically improve durability.
