RPM Losi Promoto MX Crash Structure (White) t-maxx #45 Steel is black finishThe RPM Crash Structure (Radiator) for the Losi Promoto is here to solve those pesky breakage issues. They strengthened the most common stock breakage point by adding mock louvers the full length of the "radiator". These louvers are actually strengthening ribs that look like angled fins used to deflect rocks from hitting the radiator on full sized dirt bikes. By adding that extra scale touch, RPM increased the strength of their version significantly.
