I have been a owner of this bike and yes I agree this bike so powerful and has a great pick up. There were so many issues I faced in this bike this had to be in service center for almost 3 months once. First time when it had a problem they had to replace engine top and its piston too.
And there few other problem in it. I took my bike for a long ride to bangalore and I almost crossed 200kms and all of a sudden the bike got seized and when checked with a mechanic nearby they have already told that engine is seized and you need to take to service center.
So then I had to put into a tempo and take it to service center. Fortunately with engine warranty they replaced engine itself but think if some other vehicle had hit me when engine failed. They have to improvise their engine quality.
