Well I did it. After much debating with this decision,I decieded to trade in my 09 650 for a 09 400. I bought my 650 just last fall and I must say it was trouble free and more power than someone like me really needs. Why ? I'm a bit of a worry wart and just could not get past the things I had read about the cvt "potencial" problems. That put aside, The 650 is a real Cadilac when it comes to bikes . Anyone that likes get up an go will have to agree, it's a rocket. Comfort is great and had no problems riding for hours very relaxed. Gas milage could have been a bit better but maybe I had a little to do with it as I have a strong right hand twist. A problem I did have is moving it around in a dirt driveway where I live, was a bear. Now for some ,this is no big deal, but i'm 165lbs after dieting and 64 years old so it's a big deal for me. I took the 650 with 13k miles back to the dealer I bought it from ,explained my problem and what I had in mind. The dealer did an even swap for the 09 400 with 2k miles. Yes I lost some by NADA prices but was happy with the deal just the same. Now, the 400 does not have the same power as the 650 but still plenty for someone like me. I find I can easily move it around in the yard as the weight is much more manageable. Comfort is about the same. Gas milage is a little better. One of the things I was really interested in finding out was hiway use. First short trip from central Maine down to Portland Me, about 90 miles of interstate at 75-80mph indicated on the speedo, Was great. I'm used to traveling hiways so feel I can say the bike seemed very stable even passing big trucks. I planning a trip in 3 weeks out to West Point NY about 400 miles and most of it is interstate. I know several have made much longer trips than this ,so I have no worries that the bike will do very well. Any ,this is my take on the 400 at this point and will plan to follow this up after my trip. Ernie.
