WORD Racing is pleased to be an Authorized dealer of the X125 & X100AC Engines & Parts. If you're in search of the best quality TaG engine on the market, or if you're looking for a smooth TaG engine, with a powerful wide powerband, this is the engine to have.

Why is this engine so appealing? For one it features a balance shaft that reduces vibration, improves driveability and ultimate durability. Other features include 40x25x7 Main Bearing (with a roller bearing upgrade available) and 20mm Crankpin. Our creativity has led to the one-piece exhaust system, a simplified wiring harness and removal of unnecessary parts from the package. What truly makes this engine unique is the option to convert from 100cc air-cooled into a 125cc air-cooled or even water-cooled as all three engines will utilize the same bottom end. 

Bringing together decades of engine building experience and innovation, the design process of the air-cooled X125 variant was a fun challenge for Valiante. "We have a lot of history with air-cooled engines. Incorporating our accumulated expertise has led us to design an amazing air-cooled engine package." 

The new X100 complete engine package retails for $2695 USD and includes everything EXCEPT battery or motor mount
