I've since added new chain & sprockets (+2 in back), did a Renthal handlebar conversion, swapped out the footpegs for the lower ones from the SV650N, and added heated grips plus hand guards. The spring project will be to work on the brakes and maybe suspension a bit. It's sort of a modern-day UJM in that regard, a basic platform to modify as you like.
I still miss my '01 SV650S. The 1K's extra power is nice but given a choice I'd narrowly
choose the lighter weight and balance of the smaller bike.
