You might have to do some experimenting with different seats. Some people believe memory foam is a better alternative to gel - I don't really have an opinion there.
One seat I had before that was deffo more comfy simply had more padding in. Unfortunately that also made it taller, and pushed the seat height up too high for me - so I sold that seat to another member on this forum. Cannot remember who the customiser was now though.
If seat height is an issue, then one way (haven't yet tried this) is to have more seat padding as above, then fit lowering links to lower the whole bike. My previous Tiger was lowered, and didn't seem to affect handling at all.
