Hi Shiva and other users I am looking to buy a new used

Hi Shiva and other users,

I am looking to buy a new/used bike. I have earlier owned Passion and now have 2003 model Activa. The reason I want to change is in Activa I feel sharp jerks while going over humps and pot holes, which hurts my back. Also I don't find it nicely balanced in wet conditions.

My priorities in preference order are:
1. Good suspension. As the roads in bangalore are bad and have a lot of humps I want a bike which takes absorbs the humps more
2. Good acceleration. I like to have a bike which has good initial acceleration. Top speed is not a critieria
3. Stability. It should be stable under sudden braking.

Considering this I am looking at FZ16, new P220, used R15 and used old FI P220. May be I can consider Unicorn too but I find it dated in terms of looks. You can also suggest me any other bike.

I know FZ16, R15 and Unicorn have mono-suspension. mono-suspension better in terms of absorbing pot holes and humps than dual suspension? I have test driven R15 and new P220. But have not driven FZ16. I found P220 also good at absorbing potholes. Does P220 retain same conditions after few years of usage. I read that mono-suspensions life is better. Is old FI P220 good one?

I know its a long one, but thanks for being patient and answering :).
