Whilst looking to see if thundercat brake levers would fit on a FZS600 I wondered why it's widely stated that the Fazer (95bhp) is based on a detuned thundercat (89BHP) engine.
How is it detuned if it has more power than the thundercat ? (I understand the thundercat probably has more low end and maybe through the rev range due to the ram-air doo dah ?)
It looks like the Thundercat has 87.7 bhp @ 11,250RPM whilst the Fazer has 95 bhp @ 11,500RPM. The Thundercat is allegedly 223kg and the Fazer 189kg. Surely the weight makes up for some of the lack of power ?
Don't get me wrong, I'm sure that the seating position and front forks and fairing make the Thundercat a quicker bike, I'm just wondering how the engine is 'detuned', it sounds like an insult since at certain times (??) it will be more powerful than it's brethren.
I know Punk likes the Thundercat and that is enough for me to safely believe that it is a cracking bike, this is not supposed to be a criticism of either bike, just a question.
I wonder if anyone can point me to a dyno from a stock Thundercat and a stock FZS as that may shed some light on it for me.

Opinions are like A**holes, Everyone has one. Some people seem to have more than one though which is a bit odd.
