I've found the progressive front springs for both bikes, I'd like to go to a heavier front spring than the progressive, but I can't find one. Anyone know of a MX bike spring that will fit if cut down or another brand that is stiffer than the progressives? Also, any rear springs that would support 240lbs out there? I've had the rear spring revalved but I can still bottom it out. That's what I'm looking for for the 250R. For the TriZ the same but for a 200lbs rider. Any help would be appreciated.
