Good to hear you didn't tumble down the hill with that big ninja. Sounds like you're getting very acquainted with the hypersport. I loved the size, comfort, stability, and brute power of mine for many years. And I agree with the quieter exhaust of the stock system. I grew tired of the loud, droning, megaphone on mine year after year. Thoroughly enjoying the stealthy tone of my GT so I dont alert every LEO in a 3 mile radius what my throttle hand is doing.
If I were you bro, I'd claim it, get it fixed, and add a Veestrom to the stable for those more adventurous rides. Having a 2nd, flickable, bike option in the garage is awesome.
