looking at progressive springs for my street twin. any body tried them yet, if so what fork oil you using.and are they any improvement
I have TEC progressive springs on my Street Twin. I'm not convinced they are worthwhile. If I was to do it again I'd buy better quality linear, and that's on the advice of a builder of race bikes and specials who knows his stuff.
I don't think Hagons are that much more expensive. I would go with the proven brand if choosing again.
Yes linear springs generally better. Maybe try a suspension specialist. Not sure Hagon are actually very good ! From what I have read about their shocks
