Yep, welcome. :-)
Ahhhhh; the "enduro" discussion! In the really old days.....1970's, Enduro was used to describe a bike with offroad aspirations/capability....used more in Europe than North America. by 1980, "Enduro" meant an offroad, non street legal dirt bike meant for enduro competition....all the big players made them, Kawasaki KDX, Yamaha IT, Honda XR, Suzuki PE, etc. My literature for my 2000 KLR refers to it as a Dual Purpose bike and the KDX as an Enduro.....I like these descriptors as they seem accurate to me - not alot "sporty" about a KLR! LOL.
....of course these days you can buy a street legal Dual Sport bike that is fully capable of racing any offroad course in the world, namely the KTM 500EXC.
Adventure bikes: all the big twins; KTM's 950/990/1190, BMW F800GS and F1200GS, Yamaha Tenere, Triumph 800XC, etc.
Dual Purpose bikes: KLR's, DR650, XRL's, KTM 690, F650GS, etc.
Dual Sport Bikes: KTM 500EXC, Yamaha WRR, and similar street legal bikes
Enduro: not many dedicated enduro bikes left; mostly KTM XCW series bikes, CRF X's
MX: CRF R's, KXF's, KTM's SX series, etc.
