The XLCH ("Competition Hot") variant was particularly aimed at riders seeking raw performance and stripped-down aesthetics. By 1970, the Ironhead engine, named for its cast-iron cylinder heads, had firmly established itself as a cornerstone of the Sportster range. The XLCH embodied a rugged and aggressive design, coupled with performance capabilities that appealed to riders looking for a versatile and customizable machine.
