2008 Kx450F or Yz450F?

[karl_1052]

With the maintenance schedule for those bikes, no thanks.

Cylinder head service every 15 hours?
crankshaft inspection at 15hrs?

You will be working on it more than riding it.

That's recommended for someone who can ride the bike to it's actual capability. About 80% of 450 motocrossers will never reach that, much less trail riding it.

And it's most likely valve checking every 15hrs in that "cylinder head service", once you have that all open you can just check and see if it's blowing up oil in there. It's good to check valves, but I know plenty who go awhile before any major adjustment. They go can anywhere from 30 to 50 hours. Hell my bike had 58 before the previous owner checked it and only 1 valve(out of 5) barely needing adjusting.

If you motard the bike that will require slightly more frequent checks as you'll be reaching much faster speeds and the motor can be spun up much higher in the RPMs than just sticking to dirt and using the retarded torque it makes.



I do recommend REGULAR air filter changes and depending on what oil you use, you can get away with the full 15hrs. ALSO since it's a brand new bike, please get one of these for it.

They make the WORLD of difference in logging when you need to service it. Have it installed before you even kick the bike over once to ride it.

My point is, that for trail riding a trail bike is so much better and easier to live with.

And I'm alright with that. I might not need a Ferrari to go get coffee, doesn't mean I still wouldn't like it.

Dude. We grew up in the countryside. We both have a ton of experience in dirt (mostly 2 strokes). You guys make it sound like he doesnt know what he's getting into. He asked for advice on 2 different bikes, not advice on how many CC's he should get.

I wouldnt buy anything less than a 450f for dirt either. And yes, I have ridden them on multiple occasions.

Ok that's great. Have fun with it, it's not my life so I don't care lol.

I just simply stated if you have 0 experience, it will be too much.

And he's stated, in this thread already, that he has more than zero experience. Much more.

We grew up in a town where its as easy to get around with a dirtbike as it is with a car. When city kids were riding bicycles, we were riding dirtbikes, quads, and sleds. Off road is nothing new to him or I. I dunno why thats so hard for you guys to understand. I dunno where you get this zero experience idea.

And after riding my friend Cliffords yz450f. i'd have to say its pretty docile compared to 250 and 500 2-strokes.
