Honda CD70 is not a good option for u....
As you will be covering 60Km/day and you are quite healthy too so i guess you should be looking at 100cc class not 70cc.
A 100cc will give you more pickup, power and comfortness while not sacrificing the fuel average too much...
-Yamaha Junoon is a very stylish, powerful and comfortable bike ... but its not from Yamaha anymore... so i will not suggest you to spend 80K on a DYL bike....
-Then there is Honda CD100 which should be good for u as it is comfortable, 100cc and still quite fuel efficient. I don't know about exact fuel average but it is much better than Yamaha Junoon from what i have heard.
-There is a Suzuki Sprinter 110cc also ... you might wanna look at that......
