Isn't the 180 parallel twin boring (sound and feeling) ?

From an outsider perspective, I love the Ninja 400 for what it is : light, flickable and you can pin it down safely.

But the engine is still a 180 parallel twin and I'd like to know how ninja 400/500 owner feel about it. Do you think the rest of the bike make it up for it or do you think it suits the bike perfectly ?
