[What Bike]: Karizma ZMR but with better milleage

Hi guys

I am new to this forum and specifically joined XBHP to ask about this query.

I am a previous owner of Unicorn Dazzler and am currently using (my brother's) Karizma ZMR (2011). He'll be coming back to Mumbai soon (1st of Nov,2014) and I need a new bike soon.

Here are the requirements:

1. Daily commute of about 40km (bothway): Mumbai to Navi Mumbai and back
2. About 1/3 in city and and 2/3 in Highway
3. Last 0.5km stretch of road on both ends is terrible
4. Comfort is top priority. Don't want to break my back (weigh above 90kgs)
5. Should be strong/durable. The roads are absolutely messed up . Want a bike that can handle a sudden bump on 40-50km/hr speeds
6. Should have decent mileage (don't want to spend more than Rs100/day on petrol)
7. Should have THAT road confidence (ZMR is amazingly stable compared to my previous Dazzler)
8. Budget: about 1 lakh at a stretch

I have heard bad reviews about the new ZMR. A user told me it has lost its road grip, fairings rattle etc.
How about a second hand ZMR (on other note what mileage should be expected from an 3-4 year old ZMR). The fairings/plastics rattle a lot on the current ZMR ( but my brother's ZMR has seen a lot of bad days)

What about pulsar 200ns? What would be the comfort and the mileage better than ZMR. Would it last more than 2 years? Does the 6th gear help in increasing mileage (if I say do 60-70 in 6th gear) What about the perceived maintenance of Bajaj bikes?

What about Suzuki GS150 with the sixth gear. Looks are "commuter" bikes, but will it perform better in terms of comfort, top speed and mileage

Yamaha FZ V2/FI ? How is the new fuel injection variant? Is comfort/suspension good enough for long journeys?

Other bikes ? RTR? Second hand Thunderbird ? Any other suggestions please?

PS: Absolutely hate to lose my brother's ZMR, absolutely love it. Are there better bikes than ZMR that suite my needs?
