My (quasi) street legal Husky FX 350 with tail bag, bar bag and about 3 g of fuel (5 g ) tank. weighs 250 lbs. I expect the 500 exc would be a bit heavier as it is designed as an enduro rather than a race bike. For comparison, my DR 650 with tank bag, tail bag and 3 g of gas weighs 385 lbs. (5 g plastic tank and titanium muffler). My 2012 R1200GS with tank bag, trunk box and 4 g gas weighs 567 lbs.
