I have a 95TA with a Spec 4, I would like to step up to a street twin but cannot decide between an aluminum flywheel or a steel flywheel.

Does a ST clutch kit with a aluminum flywheel weigh less than a spec 4 clutch kit with a lightened spec flywheel?

 

my fidanza alum flywheel is touchy to drive in traffic...granted it's mated to a spec 4.

it spins up nice and fast though.

basically...drag race stick with steel
autoX or road race...alum

 

I have the ST with the aluminum flywheel. I believe this setup weights the same as the stock setup (the extra weight of the second clutch disk and intermediate plate are offset by the lighter flywheel).

 

like OBE said, its probably a good idea to go with the aluminum because the street twin is by nature alot heavier, the aluminum flywheel may offset it and give you more of a stock feel

 

I have the ST with the aluminum. As said above that is pretty much my opinion. Leaving without enough gas the motor likes to "lope" like a cam until it grabs all the way...just a different feeling i guess. Revs up quick...traffic isant that bad. Overkill for my car but overall i like it.

 

Has anyone actually weighed any of the setups to get a better idea of the weight differences, seems the aluminum flywheeled ST setup would weigh about the same as a spec 4 with a lightned spec steel flywheel. Due to the ST have the extra disc and floater plate like OBE1 mentioned.... anyone actually know the weights?
