Surprise over Yamaha sz-x on Second service

After the First service my bike look smooth and gave extra 3 km millage. I gave the bike for second service on 8th jan 2011 . I expect more than 50 km millage after second service. Even if we get this 50 km millage then this is excellent bike in its segment. I was surprise when i took the bike from second service. i saw another SZ bike with some difference. when en-quired about it they told that it is SZ-R which comes with DISC brake. I was shocked that i waited for this, but unfortunately it come late for me to buy. SZ-R looks great. But My Bike also great.
