The wait is over. The legendary green machine finally gets its SmartCarb! The all-new 34mm unibody SC3 is now available for the Kawasaki KDX200 and KDX220R.

Designed specifically for the KDX, this new kit is a direct, plug-and-play fit with zero modifications required. Unique features include:

🟢 Large capacity floatbowl (the fuel you need when you need it)
🟢 High-flow 3.8mm needle seat (quicker fill rate and response)
🟢 Bigger internal vent passages (faster fuel pick-up)
🟢 59mm extension ring adapter (fits exactly like the stock carb)
🟢 40° throttle cable guide (accepts stock throttle cables)

The KDX200/220 is arguably the best bike ever made. SmartCarb makes it even better. Get Equipped.

Mean & Green

Performance doesn’t have to come at the expense of efficiency. In fact they go hand in hand. No other carburetor atomizes fuel as finely as the SmartCarb does with its single metering rod fuel circuit. Finer atomization leads to more complete combustion - making more power while using less fuel.

Stay mean, green, but never lean. Get Equipped! 🍀

The only corners we cut we do with a 5-axis CNC, and that ethos is true for our anodizing as well. No compromises allowed. The best carburetor made today deserves the best anodize. 36, 38, and 40mm SC3 model SmartCarbs are now available in the following 7 premium hues👇

🔵 Blue Magnum
🔴 Cherry Red
⚫️ Obsidian Black
🟢 Mean Green
🟡 Midas Touch Gold

The Best, Even Better

All-New SC3 SmartCarbs, On Sale now through 12/7🔥

SmartCarb redefines carburetion in ways no other fuel system can and the SC3 raises the bar even higher in a slimmed down, radically simplified design. Everything you need, nothing you don’t.

Patented, single circuit fueling combined with integrated venting deliver ultra-fine fuel atomization and mixture control - maximizing power, torque, and throttle response from idle to WOT. Complete tool-free adjustability lets you tune track or trail-side in seconds, from the seat! Once dialed the SmartCarb doesn’t care how high you ride or how cold it gets or how far you go - it compensates automatically for air density changes while boosting fuel economy by 25-30%!

SmartCarbs are proudly and precisely made in the USA and are available for 65-500+cc 2-strokes and more. Get Equipped! 👇
