From the CNet review of the M410R:

We were modestly impressed with the Kyocera Finecam M410R's responsiveness but not as bowled over as we had hoped, given Kyocera's bold claims about its RTune technology. On power-up, the camera's display makes it appear ready to shoot in a quick 1 second or so, but we could not actually get a first shot off in less than 3.6 seconds. That's reasonably good for a megazoom model but not earth-shaking. We measured shutter delay with autofocus at 0.8 second, also good but not class-leading. Likewise, shot-to-shot time is about 2.5 seconds with image review off (4.6 seconds with review on), which is again acceptable but not notably impressive. With flash, the M410R's shot-to-shot time extends to 8.6 seconds. The nonflash shot-to-shot numbers are puzzling because, in continuous-shooting mode, the camera can indeed capture 3.3fps without pausing or slowing until your SD card is full. That is impressive.

Though we found the Finecam M410R's autofocus speed to be lackluster--thus, the decent-but-not-great shutter-delay time--the camera did do an unusually good job of follow-focusing moving subjects while maintaining 2fps in continuous shooting. The lens zooms relatively quietly and smoothly, but its zoom position is hard to control precisely, which can lead to framing frustrations.

The important part is in bold. Given this description, for action shots I would say the best approach would be to put it in whatever Kyocera calls subject-tracking AF and continuous shooting mode. You follow the rider down a jump with the shutter released pressed halfway (this keeps the AF tracking the subject) and as the rider starts to do something interesting hit it all the way for a burst of a few pictures.

Plus the ability to use a polarizing filter is also a big deal. This link explains in detail how they work with digital cameras. If you look at the sample images the various digital-domain tricks to get a polarizer effect work reasonably well, but the last image which is taken with an actual polarizer looks the best. For winter shots a polarizer is especially important.

Oh, and just in case ya don't know, a filter is just a piece of glass which screws in front of the lens. But of course, you need to have threads on the lens for the filter to attatch.
