Suzuki Releases Technical Information for All-New 2019 RM-Z250
Detailed technical information now available for the completely upgraded RM-Z250

Brea, CA (September 10, 2018) – Suzuki Motor of America (SMAI) is proud to release technical details for the all-new 2019 RM-Z250 motocrosser. The RM-Z250?s features and preliminary specifications are available on the SuzukiCycles.com website.
Redesigned for 2019, the updated RM-Z250 now mirrors the cutting-edge styling of the championship-caliber RM-Z450. An upgraded engine and list of chassis changes that achieve superior performance, were developed so the RM-Z250 remains the best handling 250 on the track.
The 2019 RM-Z250 features a new cylinder head that contributes to better throttle response and power, and a new dual injector EFI system that increases performance through the entire rev-range. Exceptional handling from a new, lighter aluminum frame and swingarm contribute to the RM-Z250’s advancement as well as a new KYB-supplied suspension that includes a new coil-spring fork. Race-ready Dunlop MX33 tires and improved braking performance increases stopping power and feel with a larger front brake rotor to help keep the rider in control.

Back in the pits, tuning the new EFI system for maximum performance is easy thanks to Suzuki?s proven fuel-coupler system.
