The BMW R1200GS Adventure starts at $18350. The R1200RT starts at $17350. Doesn't make much sense to me but Triumph has long had price at its advantage so I think they will get the Trophy below the cost of a [similarly-optioned] R1200RT.
The Concours 14 is $16k and the FJR1300 is a bit below that. The Triumph may be similarly priced.
