I got a new Honda 100 in September, 2010.
I also had lots of questions in my mind while making a decision between Yamaha Junoon, Honda 100, and Suzuki Sprinter. I came here and searched different threads and finally opted for Honda 100.
A brilliant bike! Very comfortable, smooth, powerful.
I am out of running period already and have attained 90+ km/hr while doing "double sawaari". The engine was very smooth and quiet during this. Awesome na?
Well, brother, it does not have any washing issue as a brother above reported in Yamaha Junoon. It starts on first kick, Alhamdu Lillah, even if you see that the plug cap has water over it. There are no electrical issues after a wash.
I have so far achieved a mileage of 57-58 km/liter.
Moreover, Honda 100 gives a good feeling and extra comfort to tall guys as its height is greater than other conventional bikes available in our market.
So far, the only thing that bothers me about Honda 100 is that it troubles in starting in cold weather, I have to start it with choke when the engine is cold. Besides that, I don't see any troubles with this bike so far.
My suggestion: Go for Honda 100.
If you have any more questions for me, I'll be glad to give as much information to you as I have about this bike.
