February 27, 20188 yr My SY has the white progressive spring. Wondering if anyone has the later year bike with the yellow spring. Need an accurate wire thickness and number of coil wraps if possible. Wanting to find a straight rate spring for mine to try.
February 27, 20188 yr Author Wanted to add, if anyone has a SY250F or SR280; the measurement of the spring wire diameter on those may work also.
