since i so free calculate.. might as well calculate the theory persona max speed

FD = 4.052
4th gear = 0.976
5th gear = 0.804
max power at 6500 rpm (according to spec)
Tire circumference = 1.932 meter
4th gear 6500 rpm
----------------------
6500 / 0.976 (4th) = 6660 rpm at 4th gear
6600 / 4.052 (FD) = 1643.6 rpm at FD
1643.6 x 1.932 = 3175.42 meter per minute
convert to hours = 3175.42 x 60 = 190525 meter / hour @ 190.5 km/h ..
5th gear
---------
6500 / 0.804 (5th) = 8084.58 rpm at 5th gear
8084.58 / 4.052 (FD) = 1995.2 rpm at FD
1995.2 x 1.932 = 3854.74 meter per minute
convert to hours = 3854.42 x 60 = 231284 meter / hour @ 231 km/h ...
(well, i doubt 112bhp got enough juice to push this speed thou)
Seems like Inspira gears also give similar top speed with stock rim and tire at 6500rpm...
