Howdy Ridaz? Par728 from the tdot. Just started riding last year and first bike was a street750 and now the cbr650f. You just gotta love the torque-ness of the street750 but overall the 650f takes the icing on the cake! Its just hands down the best ridability between the two. The sound? Oh so good! Music to my ears! Right now its just stock the 650f but i put an extra horn and LED bulbs and purchased kn air filter, led relay, battery indicator which i havent installed yet. Maybe for long terms if the dough would permit would be the arrow racing full exhaust (out of all it has the most gains +5hp) Not much to see for engine internals. Wanted a carbon wheels but again none available. Hoping to chat with all y’all soon! Let’s ride!!!!
