Pulled the trigger on a 2007 TE 610 with 3.000km (2.000 miles). Just ordered a LV complete exhaust system and may will try a JD jet kit as it's a carbed model. So far just changed rear tire as it came with a DS tire. Will check cam chain tensioner when it's around 6.000 miles. So far loving the bike in some 4x4 roads and light trails, but found the suspension to be on the stiff side.
I'm 5'6" tall and 165 lbs w/o gear, but the bike height isn't an issue as I've ridden enduro bikes since when I was a kid.
