Oil-cooled GSX-R750/1100 Rear Master 69600-17C01 Early 750 also RK J-L 1100K-N set saves you 870 yen!

Suzuki genuine rear master 69600-17C01is used on various models.
For now, let me narrow the discussion to oil-cooled models only

The piston and cup set used for rear master overhaul is listed below
● Oil-cooled GSX-R early~69600-16820 Same
● Oil-cooled GSX-R later (17-inch type) 69600-04810 Same
◎ 1200 series 69600-04820 Set
[ Early 69600-16820 ]→ Later 69600-04810-000 Piston/cup set part numbers unified
They’re the same. But if you order separately for the 1100 and request the 1200 series…

“You save 870 yen and ordering becomes easier with just one part number.”

Then arrange O-rings and rods together and it’s perfect (*´ω`*).
*Since it’s a 1200 part number, the 1200 works with this too

Subtly, the return port gets clogged → lock. Be careful (*´ω`*)
