I would agree, i think a std zed has more than enough power for a spirited road drive and overtakes, but guessing a lot of people just look at straight line acceleration as per the original post. Still would like the extra 100 per ton though, nicer to have more under your right foot if needed
Whilst i was into bikes i mainly had sports bikes, but i did own a Ducati Monster 900 for a year, on normal roads your mates would leave you for dead, but when it came to b roads, there was nothing in it as they just couldnt use the power.
