First up, I'm 34, clean riding/licence record, and the cheapest I can get insurance is through Insure My Ride/Swann, and it's $1100-1200. I'm rating 1, and it's still stupid expensive. Insurance changes based on where you live, and other various things they like to use to rip you off.
Second, Suzuki are releasing engine casings but when I contacted them they dont' have a release date. I hate the knobby sliders too, and usually dig into the road and cause more damage to the bike. I'll probably be getting R&G or something from Brisbane Motocycles.
