Gold Anodised Forks
Cosmetic and effective, marking the SE out at a glance. Kawasaki understood that buyers paying more want it to be visible.
Built in Small Numbers
The SE has never been produced in the volumes the standard RS manages, which keeps used values firm and examples hard to find.
The Reed Assembly
A moulded housing holding one reed per port, bolted to the cylinder head cover and fed by a hose from the airbox. It is the half that physically admits the air.
A Cracked Reed's Signature
Soot inside the airbox and an element discoloured well before its interval. It is almost always found while chasing something entirely unrelated.
The Hose Port Stays Open
Removing the housing leaves an opening at the airbox unless that end is closed too, and unfiltered air into an intake is worse than the system ever was.
An Older Head, Careful Threads
On a machine past a decade the threads have been undisturbed for a long time. Working slowly and cleanly is worth the extra few minutes it costs.
Two Fasteners, Usually
The housing is held by a small number of bolts into the head, and the cover uses the same ones in the same positions. Nothing is fabricated.
Careful Threads
On an older machine the fasteners have been undisturbed for years. Working slowly is worth the extra minutes it costs.
Brembo Behind a Retro Front End
The SE carries genuinely modern braking behind 1970s styling, which is the whole trick of the model. Underneath the appearance it is a current Kawasaki with all the hardware that implies.
Built in Small Numbers
The SE has never been produced in the volumes the standard RS manages, which keeps used values firm and makes good examples genuinely hard to find.
