Bought my 2013 used last June with 5,000 miles on it. It now has 26,000 miles on it and the only issue it has had is it uses 1 qt of oil every 4,000 miles since I bought it.
My XC replaced a 6 month old 5,000 mile fat underpowered crappy clutch of a pig 05 GS1200 which I hated, except the neat red lit instrument cluster.
The engine and trans are a jewel and are just like a little brother of my old 97' Bandit 1200S that I owned for 16 years and 85,000 + miles. The GS1200 was more like a giant KLR650 which I had owned one for 2 months and had hated too. I guess 30 years of sportbikes has tainted me on engine feel and performance.
My first choice was the BMW 800 per the test reports, but I got gun shy that it might have some of the hated characteristics of the GS1200. Plus people want ridiculous prices for used ones and more warranty/quality issues that I wanted to deal with.
I mainly ride it to work, 150 miles round trip every day if it's dry, all year round. 50 mpg no matter how I ride it.
I do all of my own maintenance. The chain and sprockets are still like new as they get lubed every other day.
It had new TKCs on it when I bought it that lasted 14,000 miles. Now it has Shinko 700s with 7,000 miles on them with 50% tread remaining.
The Shinkos are noisier, but they cause way less (almost perfect smoothness) of the dreaded front end hop the front suspensions are known for.
The only mod being pondered is RACE TECHing the suspension which I did to my Bandit and 01 DRZ400S (which I still have).
