I purchased this wonderful bike on September, 2006 and continuously using the same since then. It is one of my pride and still it is a traffic head turner. Except some minor problems like regular front shocker oil leak, cool starting problem and hind mudguard touching the tire and making noise in double carry, I did not find any major problem.
Though I must say that Royal Enfield after sell service is not so good, but you can get a number of road side service man who can satisfy you and your bike. Price of spare parts are a little bit high, which is very much expected and mileage is around 40kmph, which is again very reasonable. I have made a number of long trips (More than 200-300 kms at a stretch) double carry on this bike and had no major problem en rout.
This bike is a class apart and makes a completely different segment of its own.
