Hi Vojko,Thanks to both of you. Upgrade would be too expensive.
Do you have any link where I can buy camel tank which mounts on the rear?
At one time I was wondering if I should change. Once I saw what the seat height was going to be I decided not to make the change. Instead I fitted a Camel Tank, 6.5L and I did the Hyperpro suspension upgrade. Its a totally different bike now.
