Built with a clamp mount for direct installation and a sealed M8 plug for weather resistance, the 300X is engineered as a durable replacement or upgrade for worn stock throttles. It supports a broad voltage range (12v–72v) and is compatible with common hall‑effect controllers that accept a three‑wire signal.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the 300X fit different handlebars and sides?\u003c\/h3\u003e\n\u003cp\u003eThe 300X clamps directly to 7\/8\" (22mm) handlebars and can be installed on either left or right side without modification.
