First things first: the pre-sale process. Will has been terrific and very kind, guiding me thru the buying choices.
I went for a Stage4 w/ 2x 59mm velocity stacks and decat w/ESE (plus SAS/canister removal) for my 1290GT. My fear was that all the increase would be in the hi end of the revs range. But at the first ride after installing the whole kit, holy cow, the results were awesome, jaw dropping… Let aside the roaring sound, it's unbelievable how the bike gained personality, increased in reactiveness, and surprisingly the torque seems kicking in even at lower rpm. Man, the final result is way off the chain: if I were told that that's would the deal I wouldn't believe it. A true game changer, totally rad. Endless kudos to the Rottweiler team!
