The 'Mech is built on a lightweight Endo Steel chassis which supports a Vlar 300 XL engine. The Toyama has a top speed of 64.8 km/h, making it capable of keeping pace with most heavy 'Mechs. The Toyama has an impressive twelve tons of Durallex Heavy armor. To dissipate heat, the Toyama carries fourteen double heat sinks. The 'Mech also carries a Garret/Guardian Interface Guardian ECM Suite to protect the 'Mech from advanced enemy electronic warfare systems. [Source: sarna]
