That's good if they can provide you the bike within a week.
Now regarding choosing which bike I would say both the bikes are different.
Let me try putting some points which differentiate both the bike:
With r15 v2 you get more power in terms of PS and Torque.
Better handling and performance.
Braking system is just amazing and gives you immense confidence on road.
R15v2 has more sporty look as compared to FZs and it looks like R1
You get disc brakes on both front and rear tire
R15v2 is lighter than the FZs
FZs is better suited for 2 people as compared to r15
Is priced lower than the r15 but then it losses quite a few things as well
I guess the FE of FZs would be 1-3 Kms higher than the r15
I would say if you have budget than don't think of anything else and just go for it buddy and trust me you will always be happy with your decision.
Even i was looking for a P220 and my budget was around 80-90K earlier. But after taking the TD of r15 we didn't think much and went ahead with it. It was that good for us. And i guess i did make a good choice. Our bike is reaching almost 3000 kms and so far not even a single niggle (touchwood) and everytime my brother takes the bike for a spin, there are 100 heads turned into the direction our R15 v2 zipss. BTW
: did you take TD of both the bike?
If yes than what was your initial impression about them.
