MR-04EVO2 by Kyosho (32895): refined front geometry and sensored drive
Intent and core changes
The MR-04EVO2 refines the Mini-Z package with specific mechanical revisions rather than a wholesale redesign. The update centres on a sensored MM2 brushless motor system, a lower battery location to drop the centre of gravity, and reworked front suspension geometry designed to improve steering predictability while keeping the Mini-Z footprint.
Front-end design and handling benefits
The chassis features a kingpin-integrated knuckle and an enhanced upper arm to maintain camber through cornering phases. Re-tuned caster and trail provide a linear steering response, and the fitted higher-rigidity front arm helps the chassis remain composed under load. 3 mm inner-diameter ball bearings reduce rotational resistance at essential pivots, and anodised aluminium parts increase stiffness where needed.
Drivetrain, electronics and compatibility
The set is supplied with a KYOSHO SPEED HOUSE XSPEED 41 motor (KV4100) mounted on an MM2 mount; a ball differential is included to smooth rear-wheel slip during tight turns. The control unit supports modern high-speed communications for current receivers and allows RPM tuning through the I.C.S. Setting Manager. A gyro is not supplied, so owners can fit their chosen stabiliser.
Adjustability and fitment notes
Front tread is adjustable via different lower and upper plates and by moving the steering tie rod between narrow and wide positions. Wheelbase can be changed to suit different bodies, and optional front springs are available for alternate rates. These features prioritise handling consistency and flexible body fitment.
Who should buy this chassis?
The MR-04EVO2 chassis set is aimed at Mini-Z enthusiasts, tuners, and collectors who want a modern sensored brushless foundation with improved front geometry for steadier steering and enhanced tuning potential.
