I want some advises on somethings:
How to keep engine cool as it is air cooled
I like to drive fast so what mods can i do for more acceleration and top speed
Lighting options
Other gears
I don't think aeros are really all that important on bikes that don't really get up to very high speeds.
Looking through your rear wheel, I can see that you're in a part of the world where girls aren't allowed to ride bikes the normal way - only side-saddle (that guard contraption over the rear sprocket). Maybe that's why they only have small bikes in these parts of the world? A girl wouldn't last 5 seconds on the back of a literbike if she wasn't sitting properly :lol
You are overthinking this. By a lot. And I said 100mph, which would be 160kph, and even then it makes little difference, especially on already naked bikes.
What do you guys recommend for aerodynamics on my '89 Honda NX 125? It tops out around 55mph, but I really think I could get it closer to 120mph with proper aero.
