Mark,thats the beauty of the Hagon shocks.You can get them to fit you.If your bike is a comfortable height now,then stock length is fine.Longer ones will give you more leg room [a little,anyway] but make the steering quicker,ala,Thruxton. Shorter gets you the other way,and if you leave the fork height alone,will slow the steering a bit. I believe the stock Hagon spring is a 110lb,which is IMO ok for 2up riding or aggressive solo work but ,again,IMO,too stiff for everyday riding if you weigh under 200lbs.[I have -30mm shocks/100lb springs] I use 110lb springs in summer when my wife might want to go for a ride. BC or Dave Quinn can get anything Hagon offers but you`ll have to wait probably for custom length/spring weight. Fork springs are easier,Hagon or Ikon [and others] just drop in,but ask for a fork oil change. The Hagons were good,but I switched to Ikon and have been quite happy with them. You can`t go wrong in any case.. No experience with aluminum sprockets.

Just a note,Mark, I have Nitro`s not classics.Sorry if this skews your results.
