Upgrade Your MP10 Drivetrain

The Kyosho IFW639-58S is a lightweight 58-tooth spur crafted for Inferno MP10 models. The 0.8 module pitch provides a finer tooth spacing than 1.0M, yielding crisper transitions and reduced drivetrain noise on mixed-grip surfaces.

Ratio Tuning for Different Surfaces

This spur enables closer gearing steps to tune acceleration versus top speed. The refined tooth profile helps lower the chance of gear chatter and supports smoother power transfer when exiting turns.

Parts Needed for Proper Fitment

To install this spur you will need separately sold lightweight one-piece clutch bells: No.97058LW-16 (0.8M/16T) or No.97058LW-17 (0.8M/17T). These ensure compatible pitch and reliable meshing.
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.

Is this spur suitable for carpet or tarmac tracks?

Yes, the finer 0.8M pitch helps smooth power delivery on both carpet and tarmac; select pinion size to suit surface traction.

Which clutch bell should I buy with it?

Choose either No.97058LW-16 or No.97058LW-17 depending on your pinion tooth count; both are 0.8M one-piece lightweight bells designed to match this spur.

Any tips for getting mesh right?

Set a small clearance between pinion and spur, run a marker check, then tighten and recheck after a brief run. Proper backlash prevents binding and reduces wear.
