Q. I'm traveling daily 100 to 120km so which bike is comfortable and not give back pain in between Honda Unicorn 160 or SP 125?

I used to travel around 100 km daily in unicorn 150 and never felt any sitting position issue or back pain. The sitting position was much better than other bikes of this range. This was some 12 to 13 years ago. But I believe not much changed in sitting posture or seats since then. Later I got a new high and somewhat straight handle, similar to cruiser bikes. With the new handle, apart from other trips, I travelled 200 km in one stretch and 200 km return on the same day and I felt even better than it was before.
