Kyosho IFW639-59S Lightweight 59T Spur Gear 0.8M for MP10  [KY-IFW639-59S]

Performance tuning for the Inferno MP10 with Kyosho IFW639-59S

Made for the Kyosho Inferno MP10 family, the IFW639-59S lightweight 59-tooth spur gear is a targeted upgrade for racers aiming to sharpen on-track response. The 0.8 module pitch and refined tooth geometry help deliver smoother acceleration and more consistent power transfer.

What the 59T delivers

The finer 0.8 module pitch on the IFW639-59S yields a closer tooth engagement than a 1.0 module, letting you adjust gear ratios with greater precision to suit specific surfaces or race formats. That finer mesh can reduce noise and improve throttle control under load.

Installation and clutch bell pairing

For best results install the spur with compatible clutch bells, such as the separately sold No.97058LW-16 or No.97058LW-17 one-piece lightweight clutch bells. Correct mesh and secure mounting are essential to get the intended performance improvements.
