The ultimate in torque cams, this cam offers substantial
increased in low end torque for engines up to 110 cubic
inches with compression ratios up to 10 to 1. The low end
torque increases are great for heavy bikes or for the person
who routinely shifts below 4500 rpm and wants the power
available to pass without downshifting. The cam still makes
peak power above 5000 rpm so people with lighter bikes will
enjoy the torque increases without feeling like the bike runs
out of air at higher engines speeds. These cams are used in
the ’07 and later street legal 1690 Stage II kits and the 110
Stage Kits. Compression releases may be required depending
on displacement and compression ratio. For race application This is from the Se parts catalog for the SE255 cams

Dang, I thought just about everybody knew why HD has certain motor and emissions parts that state "For Race Application Only". They do that for one legal reason. It allows them to make those parts non-EPA compliant "legally". They know they are use on street but it protects them. Been that way for years and years.

ok - so I have the SE 255s in a box in front of me (haven't installed yet) - bought at the dealership new (they had a "screaming" sale). The part number is 25638-07 and the date on the box is 10/13/09. I pulled the cams out of the box and the part number on the cam is: CVO-255. Hopefully this will put this topic to rest . . .

I believe the cams are the same. It appears the differences are in the tune provided with the "race only ' kits that Harley provides with or for these kits. The CVO bikes are delivered in a EPA friendly street tune and mechanical set-up while the stage 3 and 4 kits are not. At least that's my story and I'm sticking to it Let the flaming begin:
