YOKOMO MASTER SPEED1.0 (MS1.0) by RACEOPT

2.0mm chassis: Increases the compatibility of the car.

Motor compatible with larger spur gears (up to MAX 110)

Newly designed one-piece top deck.

Two flexible holes on both the front and rear sections of the top deck.

Option to install a bearing (3x6x2.5) in the rear section for enhanced forward traction and corner exit speed.

Original Yokomo top deck remains compatible.

Among the same gear ratio, using a larger spur gear with a smaller pinion gear has several advantages:

Better Gear Mesh: More teeth engagement increases durability and reduces wear.

More Torque: Provides better acceleration off the line.

Cooler Motor: Less rotating mass on the motor shaft reduces stress and heat.

This kit is used by Kenrick and Sean in AOC KOREA, taken TQ A1 and A4 in boosted class.
