About this product
Experience authentic Le Mans racing heritage in miniature form with this meticulously crafted Kyosho Mini-Z electric RC car. This ready to run model features the iconic Mazda 787B No.55, the legendary 1991 Le Mans winner, complete with a high-quality painted finish and expertly applied decals that capture the spirit of one of motorsport’s greatest achievements. Designed for both newcomers to the radio controlled car hobby and experienced enthusiasts, this 1/28 scale RC car delivers thrilling performance straight out of the box.

The MR-04 chassis boasts several performance enhancements that set it apart from previous generations. Updated front knuckles with integrated kingpins reduce scrub by 1.5mm on each side, whilst premium three-millimetre inner diameter ball bearings minimise rotational resistance for smoother operation. At the rear, a coil spring damper system maintains stability across varied terrain, whilst the revised caster angle sharpens steering response through tight corners. This ready to run RC car comes complete with the Syncro KT-531P 2.4GHz transmitter and is fully compatible with the entire Mini-Z Racer series body range, offering extensive customisation possibilities for RC hobby enthusiasts.
