Precision Spur Gear to Upgrade Your MP10

The Kyosho IFW639-58S lightweight spur gear is made for the Inferno MP10 range. This 58-tooth unit uses a 0.8 module pitch, which is finer than the common 1.0 module, producing smoother throttle response and cleaner power transfer on asphalt and carpet surfaces.

Fine-Tune Ratios for Track Use

This spur lets you adjust final drive to match specific track layouts. The refined tooth profile reduces lash and helps maintain predictable traction during acceleration and corner exits.

Required Clutch Bell Options

Fitting this spur requires separately sold lightweight one-piece clutch bells: No.97058LW-16 (0.8M/16T) or No.97058LW-17 (0.8M/17T). These components are necessary to match the 0.8 module pitch and achieve correct mesh.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which MP10 variants accept this spur gear?

This spur is intended for the Kyosho Inferno MP10 series; confirm your chassis clearance and pinion engagement before installation.

Do I need a special clutch or pinion for 0.8M?

Yes, use 0.8M compatible pinions or the recommended one-piece clutch bells No.97058LW-16 or No.97058LW-17 to match the spur tooth pitch.

Any setup checks after fitting?

Verify gear mesh and backlash, inspect slipper or clutch settings, then run a few laps to ensure there is no binding and that power delivery feels consistent.
