Best affixes for Street Racing bikes all around?


Location? My Bedroom.
Hi guys, so I noticed I'm not getting very good times with Street Racing bikes. I mean even with the Suzuki GSR-R1000R 2018 (The blue Suzuki bike, one of the best ones I think) I can't win much at Hard or Ace. (Yes I'm that slow with SR Bikes.)

Is there any affixes that'll help me win when driving on two-wheels in that mode, please? I'd rather know what are some of the good builds, but others are also welcome.

Thanks in advance, I really appreciate!
