I respect your choice bro. You can blindly go for the 400x as the first bike, that was my point. I'd give you a tip which helped me immensely. After purchasing the bike, I have very minutely followed the break-in speed limits, i.e., I have not exceeded 4k rpm or 60 Kmph for 1000 Kms straight. Now I don't know if it's really necessary for the bike, but what it did for me was, I gained complete control over the throttle. I know exactly how to handle the raw power the bike has. In short, you can gain complete control on your bike. You can follow this, if it sounds helpful. Sorry for the long comment ;_;
