675 '09 v '10 Street Triple

Hi Guys,

Just after a quick bit of advice. I'm scouring local dealers for a good Street Triple and have so far test ridden a 2010 version, but am looking at some 2009 ones as well which seem to be ~£500 cheaper for the same mileage. I understand that there was no major upgrade between the two years but the dash seems different and I was told the horsepower is about 7 down on the 09 version?

What are the main differences, should I expect it to ride any differently? I'm a pretty inexperienced rider and won't be riding it hard anywhere so anything subtle I guess I'm not likely to pick up on?

Also whilst I'm at it - what is considered high mileage for one of these? The examples i'm looking at seem to be around the 8k - 10k mile mark. Is this about right?
