My new Honda is as good as silent in the city and probably as unobtrusive in the countryside; very quiet coasting through villages, very civilised at speed.
My Fazer 1000 with its after-market end can minus baffle (to help the exhaust gasses to flow more efficiently of course), was not quiet.
I've detected no difference whatsoever in the behavior of other road users. Not during extensive filtering on my daily commute into London, or anywhere else for that matter.
I no longer feel like a selfish prick, I'm not attracting the attention of her majesty's fuzz and I'm sure my neighbours are happier too.
Now I'm used to riding big bikes (including the mighty ZZR 1400) and aware of what electric bikes are capable of, I view loud pipes with some derision. Of course they can sound wonderful, but in reality it's a lot of noise about nothing.
Being able to out drag just about every ICE bike on the road from the lights whilst starting from 0 rpm in silence and then only making a modest whine that gets drowned out by wind noise? Now that's effortless and cool.
Happy riding Noob and of you can find some advanced training, go for it. You'll get even note out of your riding, your family will have something to feel a little at ease about and it could well save you from danger. It's the best thing I've done and can't recommend it enough. Even if you've been riding for decades, you'll learn something invaluable!
