Resist all temptation to upgrade a bike until you've kept it a year as you'll probably want to change it anyway.
Save yer pennies for a year or two then go for either a 1000DS or a 749s.
Smart though the 620s undoubtedly is to look at, one day you'll find yourself playing catch up and scare yourself sh - sh - sh - witless.
If you like your bikes with a Sporting appearance then you'll eventually be looking for a bike that looks as nice as yours but, no disrespect cos I got on very nicely with a 750ss, has a bit more in the "oomph" dept
When you've had the use of the OE michelins

then get some Bridgestones - 010 front and 020 rear- you WILL feel a difference

Congrats on the new bike, take it easy on the road for a couple of thou til you get used to the totally different power delivery on a v-twin
