just to enlighten you a bit more rick they are normally made out of tube steel to strengthen up your front suspension, there couldn't have been much pressure on them otherwise they would have shattered, someone done a dodgie bros on them.
Two speeds... flat out and stop

Yeah, did not even cut the ends straight. Will check the spring lengths. Maybe they are a bit weak and need replaced. On the other hand maybe the guy had to raise the front end a bit after he changed the tanks. Cause if Fat Bob tanks are typical, these have got to be Obese Bob tanks. I reckon I could cross the Nullabor on one fill.

G'day Rick, I'm with Pygmy on the possibility of the PVC breaking. If you want something to replace it I have various diameters of steel tube you could use ( as I have on my own bike ) . I'm probably only 10 mins from you so could drop something off to you today or you could pick up if you wanted to. Cheers

On top pre-loads the spring, on the bottom shortens the travel a bit. Have never heard of it breaking.
Don't let your luggage define your travels.
