Still puts a smile on my face.
I had a Speed4. Great bike but I had to remap it via TuneECU.My experience with these bikes is pretty limited but from what I have read they share almost everything with the TT600 physically but what a remade fuel curve to smooth out those dips in TQ. Ive only got about 100 miles on it this season (still regular snow in MN until May) and besides a little rocky right off idle when cold I have found it to be very smooth and pull incredibly hard from 5k on up. This bike does have a PowerComander installed so that may be playing some roll as well.
