"More for Less"

The TaG Engines have indisputably dominated the North American karting scene for the past decade. And why wouldn't they? The ease of a push button, long rebuild intervals, and are consumer friendly. In Europe, the modern, user friendly and high performing KF engines have monopolized the market. Well, what if we had the best of both worlds?  The X125T engine line is a reconfigured KF engine built for the North American racer. The complicated wiring system, expensive ignition, relay and electronic box have all been removed.

Introducing the X125T-MX, bringing TaG racing to the next level.  This next-gen TaG engine allows for more power, less vibration, Internal water pump, built-in hour meter (reader required), one-piece pipe and a 15500 rev limiter with 30hp.  It will be available in a junior or a senior configuration, with restriction at the manifold.  The ever-popular Tillotson HL334A/HL334AB (23mm) carburetor will be used for Senior while the Tillotson 27mm will be used for Heavy/Masters (and the Tryton 27mm allowed regionally).  See homologation pdf below for more technical information. The accessories included are radiator, radiator cover, radiator mounting brackets, dampeners, airbox (with boot and clamp), wiring harness, pipe and battery box (with fixing hardware).

***TAG USA and IKF approved to race nationally in TAG USA and IKF sanctioned events.  Regional Series around the country running the X125T engine include:
