The 2027 Kawasaki KX327 and KX327X are Kawasaki's first all-new two-stroke over 250cc in more than two decades; a 327cc fuel-injected single dropped into a championship chassis derived from the KX450F. It ditches the carburetor for EFI, adds electric start, a hydraulic clutch, dual engine maps, and smartphone tuning, with the KX327X getting a six-speed gearbox and bigger tank for cross-country. They land late 2026 at $9,099 and $9,699. After years of the industry slowly walking away from two-strokes, a major manufacturer building a fuel-injected one is a big deal.
So what do we anticipate for tuning and performance gains?
Short answer: we're genuinely excited, and not just as engineers.
The gains we expect to find on the fuel-injected KX will likely mirror what we already proved out on the Austrian fuel-injected two-strokes — the KTM/Husqvarna TPI and TBI bikes. Those injection systems came with their own quirks and performance oddities, and a Power Commander cleaned them up beautifully. We ran a Power Commander on a KTM 250 TPI in-house and it sorted out a long list of little fueling gremlins that those early injection systems were known for. Really fine, really dialed adjustments.
So when the 327 hits our shop, expect us to come out of the gate with a piggyback solution first, and we'll keep you posted on flash capability down the road. More competition in the fuel-injected two-stroke space is good for everyone, and with hard enduro growing the way it is, a dialed-in two-stroke that sings is exactly what a lot of riders want.
We'll share dyno numbers and tuning notes the moment we have a bike to put on the rollers. Follow along so you don't miss the development updates.
