welcome to AZ Jason, nicely written first post... you'll do well around here!
yeah, it's a cable clutch & they're a pretty common thing to have fail. especially if it's never been replaced & a new clutch fitted more so if it's heavy duty. so i'd definitely be having a look at the cable, the other area that has shown the odd clutch problem is the pedal box assembly where the clutch pedal pivots or the clutch pedal bending from a stuffed clutch cable, clutch poorly adjusted etc
not sure if the one that suzistore list is non gen or not... but i'd be hunting down a genuine suzuki one.
