Key Features of the F109 99T Spur

The 3Racing F109 64 Pitch Spur Gear 99T delivers steady power flow with a 99-tooth profile tailored to the F109 chassis. Its geometry supports even torque transfer and helps maintain predictable throttle response during competitive running. The gear is intended as a drop-in option for standard F109 setups.

Precision for Setup and Tuning

The 64 pitch format enables fine adjustments to gearing, so riders can tweak acceleration versus top speed without large jumps. The gear construction aims for consistent tooth engagement and long service between inspections, helping minimise setup time at the track.

Replacement and Upgrade Guidance

Use this spur when replacing worn components or when experimenting with gearing changes; always verify mesh and pinion compatibility to keep drivetrain efficiency optimal. The part is suited for drivers who want reliable, repeatable behaviour from their F109 drivetrain.

No chassis mods are normally required for the F109; ensure your pinion and shaft spacing match 64 pitch standards for a correct mesh.
Yes, changing to different tooth counts on the spur is a common tuning method to adjust acceleration and top speed; pair changes with pinion choices for best results.
After fitting, check mesh across several rotations, confirm no binding, and recheck fastener torque after a short run to ensure the gear seats correctly.
