These YZ250 clamps reduce the offset 3mm for improved handling, flex like stock and even have the YZF's factory rubber mounting system. Riders on these models must add our 1 1/8" over-sized rubber mounted bar mounts (YZ-BBM00-CA), firm or soft poly cones (CR-PC000-KT or CR-PC00Y-KT) and hardware (MX-10125-KT). The OEM bar mounts will not fit. These clamps are compatible with the old '05-'09 and new '10-'23 front fender. Its also possible to add a Showa steering dampener (2005-23 YZ250) with these clamps. 22mm Offset recommended for Supercross (SX); Arenacross (AX); Motocross (MX); Enduro (EN); Supermoto (SM); trail riding (TR). This set is designed to improve handling (quicken steering) and place more weight on the front wheel (stock offset 25mm). Made from 2024 aluminum (same alloy the factory teams use) the set saves 7oz over stock. Included in kit: Top clamp; Bottom clamp, pressed in stem, lower bearing and pinch bolts. Usually compatible with aftermarket stabilizers, call the manufacturer to confirm.
