It's funny, I have exactly the same bikes as you (plus a Ducati SFV4S...) and probably the same problems! My Challenger accelerator goes wrong all the time, the anti-skid doesn't work, the swingarm makes a weird noise, etc.
As for the rear tire for the Rocket, Bridgestone released the Exedra G852 (with a slightly higher profile) which seems suitable for the Rocket. On the other hand, at the front, they only have the "old" Exedra Max...not sure that this one goes well with the G852!
