well the Honda is the most reliable bike on the market to me, but if your after speed go for the 140
The kawasaki would beat it easy but the Honda would have better power
the yz 125 100% better than both best mx bike ever built
Honda xr/crf 100 would be better.
I would go with the Honda all of the way. One because the Honda is more expensive but you totally get what you payed for also it is so much more reliable than the Kawasaki. if you don't ride a 2 stroke for a while it will have lots of problems getting started. There GO HONDA!!!

A kawasaki Kx 100 will go top speed at about 68-70 Miles per hour it is a 30 hp machine, and is loads of fun. I own one. :) I suggest you buy one. It' is a great starter bike!
it wood be a Kawasaki kx 65 in not experience but if he does a 85 cc
it could cause some back pressure issues and blow up the bike...
Depending on how it is geared around 70 mph.
100 cc bike has better mileage than 150 cc bike due to its engine power big engine consumes more fuel than the smaller one.
I think Honda shadow 1300 is much better than 100.
