2020 Kawasaki KX250 Baseline/Start Up Settings

We had a chance to shake down the new Kawasaki KX250 some more and went to a few tracks with three different riders to find a baseline setting for all you new KX owners to try. These settings were agreed upon by all testers that weighed from 150-190 pounds and varying from Novice-Pro.

Suspension: The new KYB suspension is a step in the right direction for Kawasaki in 2020, but we felt it was slightly unbalanced coming from the showroom floor. The fork held up well on de-cel, but the shock rode low in the stroke at times under acceleration. All riders agreed that they could use a better balance/ride attitude around the track. Try this setting in order to get the KX250 to hold up in the rear more under acceleration while trying to keep comfort on de-cel. 


Fork:

Compression: 12 clicks out

Rebound: 9 out

Height: 5mm 


Shock:

L/S Compression: 5 clicks out

H/S Compression: 1-1/4 turns out

Rebound: 15 out

Sag: 103-104mm

Engine/Coupler: We tried all the couplers and while most agreed the stock green coupler gave the most overall useable power around the track, the riders who had cornering technique issues or slower entrance speeds, liked the white (lean) coupler better for low end recovery and rpm response. The white coupler will fall of earlier on top end and not have quite as much over-rev as the green coupler so just know you will lose some of the KX250’s superb top end pulling power. The black coupler will be good for extreme hard pack or loose conditions. The rear of the Kawasaki will hook up better as well as make the chassis feel more planted on throttle. The black coupler will also be friendlier to riders that are new to 250F’s and will not have as much rpm response to scare them off.

ECU: We used Kawasaki’s Calibration Tool to tweak the fuel and ignition timing in order to try and get some of the 2019 KX250’s bottom end/torque back. The 2020 did lose a small amount of low end, but we were in the market to get some of that back for 2020. The map you see below will get you some of that torque back when exiting corners while maintaining the excellent mid-top end power that the 2020 comes with. Use the stock green coupler with this ECU setting…

Rider Triangle: The test riders we used ranged from 5’8 to 6’0 tall and all used the stock bar mount/footpeg position. If you’re 6’1 and above going to the forward hole with the mount back is a good way to get some added/room comfort when sitting. If you like the 7/8 sized Renthal handlebar, but find it too tall for your liking, go with a 983 Renthal 7/8 bar as that bend will be slightly lower and flatter.

Gearing: 13/50 gearing is just fine for the Intermediate to Pro level rider with either the green or white coupler. If you’re a heavier rider that is lazier in corners you can try a 13/51 gearing to help you get back into the meat of the power sooner. We suggest using the green coupler with our preferred ECU setting with the 13/51 gearing however. This will ensure that mid-top end pulling power doesn’t fall off too soon.
