cylinders 70cc

which is the best cylinder that provides good accelerations and good top speed and moreover runs good with the factory cranks and carbureators ,variator.also its good to refer which one is better than the other and which has the best metal(well maded ) So lets see what cylinder we have
1)stage6 sport pro mk2 70cc
2)stage6 street race 70cc
3)airsal kits sport or racing
4)malossi 70cc
which one of them is the best .Can you tell me your opinions?i want a cylinder for a daily drive with good acceleration and top speed

I think judging by all the reading I have been doing that they all tick different boxes,stage 6 pro mk2 for speed,airsal for price,malossi for daily driving you will get less more miles from it, I would go for the malossi if you don't want to be messed about changing rings every few thousand but that's my opinion

NRG2002 thank you so much about your opinion .Yes thats true, malossi is reliable also i propably buy stage6 pro replica so thats why im thinking about stage6 sport pro .Do you know any other cylinder kit that is good and provides good top speed ?Im thinking of buying malossi or stage6 sport pro mk2 .Thank you again.Greetings

Well after a lot of reading on these forums and others Trophy Top performance 70cc kit doesn't seem a bad one either

well yes but its a bit expensive than the others but it seems fine .Thanks in advance
