TR9080 is the model number for an oem TTX from a 675R. They do not have the same valving, adjustments, or adjust range. The TR889 was the aftermarket model at the time I was doing my research in 2011 (model numbers may have/probably changed since then). I talked with the guys at Kyle Racing and Dave Moss about this a lot before I purchased my Ohlins shock. The oem TTX is made by Ohlins, it's just a different model and not the same "quality" as the off-the-shelf units. Granted, unless you're an AMA or higher level rider, you're not going to really feel the difference. The oem TTX shock is way better than the standard KYB shocks on the non-R models. But unless you're going to get a sweet deal on an oem TTX, spend the couple hundred more on the aftermarket model. Think of it this way when buying a used shock: A smart guy changes the oil and other fluids on a used car after purchase because you never know how it was treated or when it was serviced last. Same goes for a used shock, and you'll spend 200-400 having it serviced. So unless you're getting a killer deal on a used shock, the price of the shock + servicing will put you up to or near the price of a new aftermarket one that's better to begin with.
Antirich knows they aren't the same because he decided to delay selling his TR602 when he learned from various questions, research, and pictures in his for sale thread that the oem TTX is not the same quality as an aftermarket.
