well its top speed may be 90+
but i just attained 85km/h due to safety measure i never cross it 85km/h
in fact just once i did it
air filter its self has no problem
but to fix it in its box accurately is a problem
with improper fitting u can feel missing during the ride
more fuel consumption and less speed
every time i got tuned the bike i face this problem
after 2,3 attempts mechanic fit it accurately
