The multi-model friction listing emphasizes modern CB900 reference 22201-MAS-E00 and six pieces for that application. Its CB450SC line instead names 22201-302-000, 22202-ML4-610, 22202-ML4-611 and 22202-MV8-920 with one used. Preserve that distinction and the exact Honda stack sequence when ordering and assembling the parts.
Spring guidance calls for free-length measurement plus friction, steel, basket and hub inspection. Steel guidance adds warpage, blue heat spots and scoring. Weak springs can contribute to clutch problems, but the four-spring package does not establish that the retained plates are serviceable or identify a numerical stack limit.
Use the CB450SC line: one piece in the 22201-302-000 / 22202-ML4-610 / 22202-ML4-611 / 22202-MV8-920 reference group. The title’s 22201-MAS-E00 and six-piece requirement concern the modern CB900F. Keep that one-position item distinct from the six main friction plates.
Check all steels for blue heat spots, scoring and distortion, then measure warpage against the proper Honda limit. Preserve the specified sequence and Plate B position. The separate listings identify six main steels and one Plate B, but inspection determines which retained pieces can remain.
Measure spring free length and inspect friction plates, steel plates, basket fingers and hub. The package contains the complete four-spring set, but weak springs are only one possible cause of slip or uneven engagement. Use the findings to decide whether plate purchases are also needed.
