This SC2 model SmartCarb replaces the stock Keihin PWK or Mikuni TMX in KTM 250 SX dirt bikes, offering superior 21st century carburetor performance, efficiency, and ease of use.
Choose the 36mm size if you spend more time at low revs riding trail, woods, singletrack, enduro, or tight/technical conditions where the bottom end or low speed is a priority. Choose the 38mm size if you spend most of your time in the upper throttle range, riding motocross, GNCC, supermoto, desert, or if you are snowbiking.
Every SmartCarb ships pre-adjusted specifically for the bike for which it is ordered. Please provide information in the forms below about any engine/exhaust modifications, how you ride (riding style), and what fuel selection and oil premix ratio you use.

With the ease of tuning, EFI feel and power increase I can say without hesitation that this is the best purchase I have ever made for my bike.
I have a 2022 KTM 250 SX and I was using a Lectron carb but I was looking for an alternative with external adjustment as it can be time consuming to tune the Lectron when trying for the perfect setting for a particular track e.g richer when riding deep sand vs hard park.
The ease of external adjustment was really the only benefit I thought I would get, but I was amazed by the power increase I got and how it really does feel like I have EFI.

This carburetor is an absolute beast. I don’t regret paying the premium price at all. My 1999 KTM 250 was fouling a plug every 4 hours and had a low end bog. It was leaking and drinking gas like an olympic athlete drinks water. With the SC2 the throttle response is crisp, 2.5 gallons lasted me a whole 4 hours of riding, and I was easily able to hit the powerband with no delays. On top of that, installation was only 10 minutes. This is the best mod I’ve added to my bike and helps such an old bike run like a modern one! Pick one up if you can ?
