No. These motors
need to be revved up. They aren't designed like cars and are built to tighter specifications. I'm not encouraging anybody to redline all the time but I personally keep my revs higher up.
Say if for example my redline was at 12,000rpm, I would rev it up anywhere between 8-10K before shifting. In the city with absolutely no highway riding, my friend on his CBR600 F4i would go only as far as 3rd only and when absolutely necessary. His motor is at 48,000km.
I redline the living shit out of my Vespa. In fact, to the point where it's at WOT before I even shift. Did this on 3 Vespas. One where I tore the motor apart. It was so clean and healthy.
In the end, do whatever you're comfortable with. You are the master of your own domain.
