Q. Which is the best among RC 390, Classic 350 and Himalayan?

In what terms are you asking?All three are bikes meant for totally different purpose.RC390 is best when racing is a factor to consider. It is not a city bike and certainly does not feel comfortable when riding in traffic conditions. Its best at its job and that is track performance. Classic 350, is best suited to easy riders and is mostly preferred by riders who tend to go for tour aswell. Its old school design is appealing and has its own charm. It certainly cannot be compared with any other motorcycle regarding the performance figures. If you love the classic, then you buy the classic. So it is as easy it can be to decide. If you want to look for performance check other charts.Himalayan is an off road bike, it doesn't mean it can't be ridden on roads! But it is not designed for city riding. So if you are mostly going to ride in the city and off-road is not your kind. Then do not buy this. But if your city roads gives you an off-road experience, then you might consider this bike as the suspension does a great duty.

Mileage and Daily Commuting: RE Classic 350 (Noise from the head is irritating and not that expected level of satisfaction)Offroad Sports and Commuting: RE Himalayan (A good commuter and adventure driving)Track Racing and Highway Rides: KTM RC 390 (Not preferred for city rides)

Classic 350 is what I suggest better.. as it cost is less than all.and also good power although there is vibration but it is good.or u can buy Himalayan it's also good. But I will not suggest RC as good for long tours
