two things Tenny
1) Read the other article I posted. I think the bike is worth spending money on. Even if the total outlay was the same i'd buy the suzuki over the triumph and the duke or a ktm (Honda cam close though). Simplicity and light weight are virtues
2) Depending on how much you weigh — ideally between 75 and 90 kilos, you might get away with just the compression adjuster up front and a basic Touratech or progressive shock in back. I'd buy the Touratech if you're doing a lot of two up because of the preload adjustment.
But either way, the total cost outlet would be about 1600 (you could install the shock yourself, it's not too hard.
if you weigh more or less than that amount then you might need to do the front cartridge or the Racetech thing, which will add money.
Good luck and say hello to John for me.
