This INJORA 180 Pro 48T motor and transmission is a solid upgrade over stock. Install was simple, the fit was clean, and the low-end torque boost is immediately noticeable. Throttle feel is smoother and the rig climbs with way more control and confidence. It’s not a high-speed setup — this is built for torque and trail performance, not racing. If you’re chasing max RPMs, go lower-turn or brushless. But for crawling and scale driving, it’s a great value and a big performance jump. Pros: • Strong low-end torque • Smooth throttle response • Easy install, good fitment • Great upgrade for trail/crawler rigs Cons: • Not for speed builds (torque-focused) Bottom line: Perfect upgrade if you want more grunt and control. Would buy again.
