I'm 6'2" and 300 lbs here. Changing the stock seat was the first on my list. I had Mean City Cycle rebuild mine 1" higher and 2" back. That made a difference for me.

I've not changed from the stock bars but risers is on my list in the future; though I find the stock position to be quite comfortable after I rode for a month. I'm only adjusting to see if it improves the ride any - not to solve a problem.

I have the Kury mini floorboards and love them over the pegs. It gives me more foot positions and I didn't notice any ground clearance difference.

I have the Ergo2s and they work great. I have long legs and didn't need the forward extension the Ergo3s give - so I was able to save some $$ there.
