I have the first engine listed in a considerably hopped up RRR. (Still pretty new) Just installed a K-Factory amoung several other options 4 weeks ago.
I just bought a second RRR with the EXACT SAME
option items as the first. Not a single thing different!
. All settings are the same, except this one has the Speed Tuned Motor.
As soon as I complete my comparison test, I will post it.
