Segment: Enduro/Offroad
Production years: 2010, 2011
The 2011 model year RM-Z250 introduces a lot of tweaks destined to make the bike more reliable and offer a more rewarding riding experience. The bike does not sport major changes, but the bevy of upgrades are indeed making it different from the previous model. The intake and exhaust timing has been revised for a better engine feeling, while the exhaust pipe was updated to meet AMA noise regulations (94 dB). The ECU settings were obviously updated accordingly, and the radiator hose routing was improved for better cooling.
Starting and shifting has been improved, with a focus on the redesigned kick starter lever and the 3rd and 4th gear. The wiring harness routing and the fuel line cap are also on the upgrades list.
