SUZUKIRM-Z450 2010 - 2011

　　Since the quarter-liter RM-Z was updated for 2011, its bigger sibling, the RM-Z450 could not be left as it was. Suzuki introduced the same upgrades for the bigger off-road machine, and it is now compliant with the stricter AMA noise regulations (94 dB). The intake and exhaust timing have been revised, as well as the exhaust pipe, to provide the improved power and a better feel of the engine.

　　The ECU settings have been updated too, and riders can easily select between two mapping using the corresponding couplers. The compression ratio has been increased from 12.2:1 up to 12.5:1 for higher output.
