Mini-Z Sensored Brushless Chassis MR-04EVO2 (W-MM/5600KV) by Kyosho 32894  [KY-32894]

Kyosho MR-04EVO2: sensored brushless Mini-Z chassis with strengthened front geometry

Chassis evolution and engineering intent

Kyosho's MR-04EVO2 refines Mini-Z packaging while improving mechanical stability. The platform carries forward MR-03 layout principles but incorporates a sensored brushless motor and a lower battery mount to shift mass downward. The front suspension has been reworked using a knuckle with integrated kingpin and an updated lower arm to improve camber control and to make steering inputs more consistent.

Mechanical characteristics and component choices

The drivetrain incorporates seven 3mm inner-diameter ball bearings to cut rotational losses. A ball differential is included to soften left-right rotational disparity during cornering and to permit controlled slip. Aluminium parts are finished in a silver clear anodise. The factory motor supplied is the KYOSHO SPEED HOUSE XSPEED 56 rated at 5600KV and the kit includes spare pinion options to tune gearing.

Chassis geometry and adjustability

Front tread adjustments are possible through swapping the lower and upper plates and by changing the steering tie rod, and the chassis supports multiple wheelbase settings for different Mini-Z bodies. Caster and trail revisions aim to give steadier steering behavior. Front springs of different stiffnesses are available separately for handling adjustments.

Who this kit suits

This chassis set is intended for enthusiasts who prioritise robust mechanical packaging and precise component selection. The MR-04EVO2 Mini-Z platform is best for those who plan to build and fine-tune a compact sensored brushless model rather than buy an RTR car.

With a sensored brushless motor and targeted suspension improvements, the Kyosho MR-04EVO2 tightens Mini-Z handling and offers a durable, tuneable platform for serious builders.
