Great choice for a 250F
The Good
Fantastic motor that is easy to use. Motor mods over the 2022 are a noticeable improvement. Ergonomics are very neutral, easy to move around on. Great chassis feel, doesn't beat you up. Nice light clutch pull and feel (ARC levers used). No complaints on suspension (170 pound Vet B/C rider).
The Bad
Muffler far too raspy and loud. Grease chassis (like most manufacturers these days). Air filter swap is a little more tricky than previous generation, but manageable.
Overall Review:

Overall a very balanced easy to ride 250F.  Suspension set up for riders weight and ability are really the only thing it needs for the average rider.

• Kawasaki Launch Control Mode (KLCM) with push-button activation electronically manages engine output in first and second gear to minimize wheel spin when moving off; normal ignition mapping immediately resumes and full power is restored once rider shifts into third gear
• Comes standard with three different four-pin couplers, allowing riders to select pre-programmed fuel injection and ignition mapping to suit their riding style or track conditions (standard, hard or soft terrain settings)
• New valve pitch: 1.5mm narrower pitch for the intake valves and increased clearance at the valve seats to deliver increased cylinder-filling efficiency and improved combustion for improved peak performance
• New intake valves: reduced by 1mm for increased cylinder head and valve seat reliability as well as to accommodate the tighter valve pitch
• New redesigned crown on the 14.1:1 bridged-box piston
• New increased engine performance
• New straighter intake duct with short, tapered intake funnel
• New repositioned upstream injector for increased cylinder-filling efficiency
• New 100mm longer exhaust header pipe offers increased low-mid torque
• New racer-friendly gearing: first gear lengthened to make it easier to use in a greater number of situations; second gear also fine-tuned to offer a smooth transition from first to third gear
• New advanced ignition timing
• New fine-tuned suspension
• New tires with a wider 110/90-19" rear tire
• New lighter and wider footpeg design
• New lighter suspension bolts
• Cooling: liquid
• Engine: DOHC, single piston, finger-follower valve actuation
• Frame: aluminum perimeter; forged, extruded, and cast parts
• Available separately: KX FI Calibration Kit (Handheld) provides access to the fully programmable ECU; this eliminates the need for a trackside laptop and gives riders the ability to create custom maps for precise adjustment of fuel and ignition settings; device can store up to seven preset maps and is PC-compatible
