1. The pillion seat is good - Even better than that of Duke (softer, bigger). However, it has a very low frictional coefficient

- This means that the rear of pillion rider will not always stay with the seat. The pillion needs to holds to you tightly always if he/she doesn't want to slide away from the bike (during acceleration) or crush you towards the front (during braking). The perspective might change based on who's sitting as the pillion - But, for all practical purposes, it is a single seater
2. The mid-range is fantastic. The redline is at 10.5K RPM - This is pretty good, unless you compare to the 13K redline of Ninja 300. The advantage of RC390 is that you can accelerate from anywhere in the rev-range at any gears. You are never found wanting for power. However, since this is unlike other track focussed bikes which give most of the power in the top of the rev-range, I don't know how experienced track riders will feel in the track with this bike
3. Engine gets smoother over time - The engine is initially terrible coarse. It does get refined as time passes. However, do not expect Honda / Kawasaki / Suzuki / Yamaha levels of refinement EVER. I have the Duke - It has become smoother now, and I really hope the RC becomes refined with time too.
4. Lights (The twin projector lamps) are very good - Much much better than Dukes. There are three settings- One position to switch DRLs ON, and another to turn on the lights - The normal lighting turns on one of the projectors, and in high beam, both the lamps are on. Pretty cool! (and functional)
5. I'll say it again - Metzelers are good. Try pushing yourself over the corners more than you have done earlier and you'll be surprised. (If you are not surprised, and you fall down, don't hold me for what I said)
6. Corners AND straight lines are fun - However, since the bike is light, you will feel the crosswinds shaking up the bike at higher speeds on a highway- I am quite heavy and make up for it. I don't know how bad it will be for a rider with a light frame
7. Bike is very light - A big relief for me since I sold my mammoth-heavy GT650N and got this. Early onset of heart-attack has been prevented because of RC390 (for me)
8. The main seat is
H A R D. Prepare mentally for this.
9. The riding position is extremely committed. If you have a big belly, please reduce. (Note to self) - Again, if this is your only bike, you can't go in this one to pick your groceries.
10. A new rider will put all his/her weight on the wrist and will experience acute wrist pain. However, fear not. With practice you can definitely overcome this. This happened with my R15 too. Within a week, one can find their comfortable position
11. A lot of space to adjust - In Dukes, there is just one riding position, esp for the taller riders. In this even taller ones can adjust, move and really enjoy the rides
12. Remember to look up (esp because of the riding position!)
13. 6th Gear is
TALL - You'll find yourself manically shifting till 5th gear, and once you hit 6th it is calm after the war. 6th is ideal for cruising (but why?

) - So, avoid the 6th gear and keep the pot boiling. 6th gear is where you'll find Satori* (when you don't want to find it). The sudden change in behavior once you hit the 6th gear is very evident
Summary
RC390 is a fantastic bike - It offers fantastic performance at a very affordable price. It is not without flaws. If you can look through the flaws, you'll absolutely enjoy the experience.
All said, nothing (in this price) comes close to plastering a stupid grin on your face like RC390 - Your weekends will be an absolute blast with the RC390.
That said, if I go back in time, will I pick it up? I am not sure - I already have the Duke 390, and I would probably pick up the N300 because of its build quality, refinement, twin cylinders and high-revving nature, bigger fuel tank (and hence range). Because, I am no Rossi. I am planning to hit the tracks more often with RC390 - Nov 28th in Chennai (Orange Track Day) and also plan to go to Kari Race Track (Apex Racing Academy) in December. However, shaving a second or even 10 seconds from a lap time is not my primary objective. I just want to have fun - While KTM RC 390 offers a lot of it, given my priorities, I'd have probably done well to pick up a green N300. (Since I already have a mad mad Duke 390)
I hope I may change my mind in near future as I spend more time with it
If I find time, I'll do a proper N300 vs RC390 and a Duke 390 vs RC390 (both in my garage) comparo in near future.
