I'm thinking about a new bike. I'm on a dr650 . Being a big boy 6"4 and 300lbs I need more comfort when commuting to work 70 miles round trip. Also need to be able to ride around the desert with the kids . What's some of thing too look out for when looking at these bikes? What's considered high mileage ? I've looked at nada guide for pricing putting them between 3-6k . Am I making a good choice on the 950 or 990? I know they are pretty much the same bike other than the 990 being injected . Am I missing any other dirffrences between the two? Any help or input you could give is aprecated .
