Naked bike design for comfort since the seating position diff than fairing bike. But when wanna compare wind resisting, fairing bike win on it since the air flow pass by the fairing. As therefore naked bike, the wind resitant was high coz it was a naked.

The air flow of a design affect the speed of the bike. As for performance parts for fz, only camshaft, rod bearing, gear clutch r diff than 135LC.

The parts easy to get since it was design from the 135LC to go till 150cc with fuel injection.
