30 was exhaust alone Stock = 39 lb my Titanium system is 9 lb with carbon can .
LSL top clamp was 4 lb
Shori battery was 8 lb
Emissions was 2 lb
Rotors all 3 was 3 lb
Reflectors / tool kit factory was 3 lb
grab bar is 2 lb 5 oz
Misc Ti hardware 1.5 lb
Sprockets 2 lb
Belly wing/bracket 2 lb
Buel pegs , and ultra light passenger pegs 1 lb
I could maybe trim 2 to 3 more lb , but not wort it as rear fender keeps bike cleaner in the bad weather riding.
More Titanium , but saving money for wheels / rear shock .
59 pounds , and know I'm forgetting something .
Weight I added back = Cruise control Rostra 2 lb , Axle slider / stator cover 1.5 lb , Radar / GPS 1.5 lb , MRA wind screen .5 lb
So basically my bird is 54 lb lighter than the stock weight of 589 wet , when I add Racks , and Givi V35 bags its only 30 lb lighter . By time I pack for a tour ride its the same 589 or maybe heavier 600 to 615 wet .
However it flat smokes a C14 or my old FJR1300 that both are near 700 lb wet then pack them for a trip .
Both have far less HP than even a stock Hayabusa . Quite happy with the end results , but do miss a center stand .
