I know that the f2's have a steel frame, so I was wondering is the swing arm also steel. and if so could I get one off of an F3. and are those aluminum?

 

anyone know if the f3 swing arm is lighter than an f2?

 

I know that a magnet sticks to an F2 swingarm, so it is somekind of steel alloy, I do not know about an F3, but with an F3 swingarm you would use a wider rim and tire so any weight gain may be negated if it is not signifigant...

 

no I was more conserned about polishing reasons not weight purposes. The steel polishes but no quiet like aluminum

 

either swingarm will polish nicely! aluminum or steel its all in how much time you put into it..
