2020 Kawasaki KX250 First Look Preview

The Kawasaki KX250 is no slouch. Since 2004, the bike has won more than 160 motocross/supercross wins and 17 AMA titles. Kawasaki has totally revised the new KX250 for more power and sharper handling.

Following are the fast facts about the 2020 Kawasaki KX250.

2020 Kawasaki KX250 First Look 1. This is the most powerful KX250 engine to date, thanks to a revised design that includes a bridged-box piston and a valvetrain created by Kawasaki’s World Superbike engineers.

The 249cc four-stroke engine has a new bore and stroke of 78 x 52.2mm. The wider bore allows for larger intake and exhaust valves for higher rpm performance and a higher rev limit.

2. The 2020 KX250’s revised engine is highlighted by the following updates:

  • New finger-follower valve actuation (as used on the KX450)
  • New larger-diameter intake and exhaust valves
  • New larger-bore high-performance piston
  • New low-friction crankshaft pin plain bearings
  • New stronger cam chain and relocated cam chain tensioner
  • New shorter intake funnel
  • New larger throttle body
  • New shorter exhaust system design

4. The KX250 returns with launch control.

The push-button activation retards the ignition timing in first and second gear, allowing the most power to be utilized for a quick start. Once the bike shifts into third gear, the original ignition mapping resumes, and the KX returns to full power.

5. The 2020 KX250 returns with a slim aluminum perimeter frame, which was updated with new lower front engine mounts.

These lower mounts have changed from a through bolt to a stud bolt, increasing frame rigidity so the bike can absorb bumps better.

  • New KYB shock unit complements front fork
  • New Uni-Trak rear suspension link
  • New stiffer front and rear spring rates

7. Petal front discs return, but the braking system of the 2020 KX250 was slightly massaged for more powerful stopping.

The Kawasaki features:

  • New revised front brake pad material
  • New larger-diameter 250mm rear disc
  • New rear brake master cylinder
