Hi There

I shoot motorsport - bikes mainly with a K7, Sigma 70-200/2.8, 100-300/4 and a Sigma 1.4x TC.

K7 + 100-300/4

K7 + 100-300/4 + 1.4x TC

K7 + 70-200/2.8

I'm sure the FA300/2.8 also has great optics.
Forgot there was an FA one. I'd bet that the optics are more than up to it, but I'd have questions about AF compared to competitors.

It depends on condition and how close to the action you are but when I shoot Rally I find the DA 50-135 the perfect focal length and adequately fast.

Posts: 254 mentioned before, the gear would depend on how far are you from the action. I have track access to motocross and car racing and found that the Sigma 70-200 2.8 HSM works pretty good for me.
Here's a MX gallery

Nice shot Andres. The Sigma seems sharp enough.

I like to attend some racing meets & GPs. I'm also stuck with the Pentax version of the 18-250 and it is very soft @ 250mm. Out of hundreds of shots taken at the 2009 Phillip Island MotoGP I was only happy with a few shots from the DA18-250 and they are still quite soft.
I do not have the zoom. But you should only operate a consumer zoom at its extreme long lens when you do not have a choice. Back off to more manageable FL like 200mm and you can get better results with more aggressive cropping.

I'd say the best equipment for motor sports photography is going to vary a lot depending on the type of sports you are shooting. I've been shooting motor sports (mostly motor cycles) since last summer, but it has all been track stuff so that's really all I can comment on.

Obviously it all depends on the track, but I'd say you'd need a minimum of 300mm to avoid being limited to the few spots on the track where you can get close enough to the action without having a fence right in front of you. There's really no way you can have too much reach - even if you have a 500mm there'll always be that action you just can't get quite close enough to.

Having photo credentials so you can get on the other side of the fence obviously makes it a lot easier to get up and close, but it is not necessarily the only way to get 'professional' looking shots. Often there will be angles and perspectives you can only get by stepping back a bit (provided you have the reach though).

If you go to races you'll see that most likely you will be the only one shooting Pentax, and even though I love my Pentax I have to admit that I am often tempted to make the switch to Canon or Nikon - Pentax is just simply lacking in AF-C speed... I think the K-7 is a great improvement and does a decent enough job when there is plenty of light, but once it is overcast and/or early or late in the day you'll have problems.

Personally I use a K-7 with a Sigma 50-500mm. I was considering the 150-500mm because I was hoping the HSM would make the AF more responsive, but often I'll be too close for 150mm and I don't want to switch lenses too much out on a windy and dusty track.

Here are a couple of examples of my shots. I have many more on my website which you can find in my signature.
