Upgrade Gear for Kyosho Inferno MP10

The Kyosho IFW639-60S Lightweight Spur Gear improves driveline refinement for MP10 cars. With a 0.8M module and 60 teeth, it delivers a finer mesh that helps smooth out power delivery and allows more accurate tuning.

How a 0.8 Module Affects Power Delivery

The 0.8 module profile creates narrower gear teeth than the 1.0 standard, which lowers shock during gear engagement and makes throttle inputs more predictable. This is beneficial when tailoring gear ratios for tight or slippery courses.

Fitment and Bell Recommendations

To use the Kyosho IFW639-60S correctly, pair it with matching 0.8M one-piece clutch bells. Recommended part numbers are No.97058LW-16 and No.97058LW-17, sold separately for correct fit and balance.
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.

Do I need to change the pinion when fitting this spur?

Not always. Check that the pinion tooth count and shaft clearance work with a 60T spur, and ensure the pinion uses a compatible 0.8M pitch for optimal mesh.

How often should I inspect the spur for wear?

Inspect teeth after several running sessions and after any heavy impacts; replace if you see rounding or chipped teeth to avoid drivetrain damage.

Any break-in recommendations for a new spur?

Run a few light-power laps to let the teeth seat, then check mesh and re-tighten mounts as needed before full-power runs.
