Tamiya 95550 TRF-Racer Jr. Black Special SP - MS Chassis Mini 4WD Kit (Limited Black)  [95550]

Overview of the TRF-Racer Jr. Black Special SP

The Tamiya 95550 TRF-Racer Jr. Black Special SP is a striking limited-colour addition to Mini 4WD lineups. As a black variation of the 18613, it brings a clean look while keeping the core race-oriented design intact. Built on the MS Chassis, it balances display appeal with practical track performance.

MS Chassis basics and balance

The MS Chassis uses a three-piece nose, center and tail layout for simplified assembly. Its layout centers the double-shaft motor and battery locations, which helps achieve even weight distribution and steady handling when pushed at speed.

Body and race-oriented details

The TRF-Racer Jr. uses a lightweight polycarbonate body that helps lower the centre of gravity and resist impacts. Small-diameter wheels fitted with slick, super hard tires and the stock 3.5:1 gear ratio provide quick acceleration and efficient top-end performance on smooth tracks.

Upgrade potential and tuning

Enthusiasts can fit a variety of Grade-Up Parts to refine handling, reduce friction or add visual flair. The kit is suited to both simple bolt-on tweaks and more involved tuning for competitive Mini 4WD events or display stands.
