The stock SMT seat should bolt right on, no mods necessary. The SMT seat is more comfortable for long hauls, but remember it is dished out, so you will sit lower in the bike, and you loose the bit of orange on the SMR seat that matches the frame. (probably already know that) The seat is actually cheap compared to other parts for this bike. (I'm still trying to swallow 200+ for a tank bag!) I plan on getting one (SMT seat) myself for longer stints. The only reason I don't have one yet I think is because its so easy to ride this bike standing up which helps a lot when your putting in a long day. I have my suspension set on the hardest sport settings, but I still wish it was stiffer. Of course the roads in Southern California are probably quite smooth compared to yours.
