I believe the engines in the R and CR are the same with standard 146hp. The gearing on the CR is lower though. Later ones had issues with the stators but all should have been sorted now. The clutch slave cylinders tended to leak at about 3000 miles but once fixed are fine. Oberon seems the replacement of choice.
Some of the revisions to the 2010 models include; standard flat bars, water pump bearing, front brake piston seals, extra rear wheel bearing, modified cam chain guides, sight window for oil level checks ( apparently a pain on earlier models) LED rear light, battery charging lead pre installed etc etc. But most importantly you can get a white one! It all makes it worth trying for a 2010 model but they are pretty thin on the ground. As a riding experience any one of the 1125s will not disappoint though.
Good luck with quest
