I recently bought a pair of Hagon 2810 shocks, 240 mm. eye-to-eye, through Bella Corse Racing. The good: Hagon asked all the right questions before filling the order: rider weight with gear, bike weight, and conditions of use. I asked them to get as close as possible to a spring selection that would yield something in the neighborhood of 30 mm. of laden static sag on the middle preload setting, and indicated that I know how to shim to dial things in close.
They sent me springs with a rate of 20 kg/cm. These produced laden static sag of 12 mm. on the lightest preload setting--unacceptable. I phoned Michael Selman at Bellacorse and complained. He told me that Hagon would not exchange the springs and offered to buy lighter springs out of his own pocket. I couldn't let him do that, so he ordered a pair of 18 kg/cm springs and sold them to me at cost. He tried to excuse Hagon's screwup by talking about weight bias. I said "Nope, that won't flush. 400 lbs. wet, around 60% rear and 40% front, real close to stock distribution, and nothing in the specs Hagon was given that says otherwise. And no, my swingarm isn't sticking."
The 18 kg. springs produced 25 mm. of static laden sag, again on the lightest preload setting. I have nowhere to go on adjustment. Fortunately the combined rebound/compression damping adjustment works very well, and I'm getting an acceptable ride. Hagon should have sent springs with a rate of 16 kg/cm. Being off one step is somewhat understandable. Missing by two steps indicates that whoever filled this order was either inattentive or incompetent. Hagon offered no correction, and Michael Selman, although he meant well, was not well enough informed to make a valid recommendation on the replacement springs. Caveat emptor.
