Your seat don't seems to be so high.
Near my house, anybody sell a high seat for the Ten. (100 €. Not really espensive when Touratech sell this kind of parts 370 € ...).

But yesterday, I tried to put some bath towel on my seat to adjust the size and "emulate" a high seat. I think it is really to high for me.

Off the road is excellent selling good quality bits for the tenere but at a price. You can't go wrong with them

Yes I still have ordered to OTR. It is a good seller.
