ATC70 TRX70 CNC Billet Thumb Throttle for Aftermarket Motor Kits

Don’t compromise the classic trike feel with a twist throttle — this is the thumb throttle your mini-quad or trike deserves. Built from precision CNC billet and finished in sleek black anodize, it’s engineered to match the style and performance of Bart Moto Co.-approved builds.

Why riders love it:

• Classic Thumb Action — Smooth, natural thumb-control that feels right on vintage-inspired trike setups.
• Precision CNC Machined — Tight tolerances, zero slop, and a quality feel you can trust on every ride.
• Smooth as Butter Operation — Internal spring and multiple adjustment points for perfect throttle feel every time.
• Aftermarket-Ready Fitment — Verified to work with Nibbi PE19–PE30 carburetors and confirmed compatible on 125cc–212cc 4V engine swap kits.
• Water & Dirt Resistant — Sealed design with a gasket between the cable mechanism and outer assembly — keeps grit where it belongs (off your throttle).
• Perfect Pairing — Complements our YX140 motor kits and stands up to big-bore 212cc trike builds with equal confidence.
