2004 Dave Mirra Pro S351 Taiwan Aftermarket

As it turned out there’s not much information on the 2004 Dave Mirra Pro S351 Taiwan Aftermarket frame. However I do remember years back when I first started collecting the owner of this 2004 Dave Mirra Pro believed he had found a USA made frame. Just to clarify this was years before we all found out that the 2003 S351 Taiwan aftermarket frame (CIC serial number) wasn’t USA made either. 

For 2004 Haro released only one version of the S351 aftermarket frame which you can only buy it as a frame. Of course you can buy the 2004 Dave Mirra Pro as complete bike as well the only difference between those were the color. This aftermarket frame was only offered with a Euro bottom bracket.

What’s the difference?

There’s really no way to tell the difference between the 04 S351 Tai aftermarket frame and the Tai complete bike frame apart just by looking at them as they were both SG black. The only difference I’ve seen is the serial number on the Taiwan aftermarket frame has MIRRA stamped in the on one side of the bottom bracket and the serial number CIC on the opposite side. On the other hand, the Tai complete bike has a whole different serial number Mirra – H00XX. However, this serial number does not make it a USA made frame.

Don’t quote me on this, but I believe the bottom bracket are different. The only reason is I still haven’t found definitive information to say I’m completely sure. Unlike the 03 S351s it not as easy as looking at where the 990 mounts are placed.

Found a 2004 Dave Mirra Pro S351?

So how do you know you have, or found, an aftermarket 04 S351 frame? Firstly, it has a Haro aluminum badge (2003+ MP Taiwan aftermarket frames came with a badge.) Secondly, the dropouts don’t have any stamping or a H0XXXX serial number on the right dropout like the USA made frames. Their serial number is under the bottom bracket which starts with MIRRA. In addition, there are no 4130 CRMO stampings on the dropouts either. Moreover, another hint is the 2003 frames have weeping holes in the tubes. I’ll do a write up on all the USA made frame indicators a bit later.

In conclusion, I personally wouldn’t mind owning this frame just to add it to the collection. To sum it up, I wouldn’t call it a grail frame, but it is a nice piece of history.
