Did you always have the 18" Pegs? If they went on w/the Brembos, I would look at the weight increase at each corner vs. what was on before. Don't forget each kg of unsprung weight equals 4 kg sprung weight.

Irrelevant for a top-speed run. Top speed is HP vs drag. Weight plays pretty much no factor other than how many miles you'd need to hit top speed.

To the OP, if your new tires have fewer revs/mile then you've now got slightly taller gearing which may give you a reduced top speed if you're now hitting the aero-drag "wall" at a slightly lower HP.
