Default 2-Stroke- 4Stroke Jump

     

What is the difference in riding going from a yz125 to a rmz250? How much different is it gonna be riding and jumping?

I use to have several pingers...when I moved to the 450F I noticed jumping was much more predictable because of the smooth powerband! You will like it!

i just switched from my 01 cr250 to my new 05 crf450 and for me i find it easier on jumps. More stable mainly. I would have to be carefull not to send the nose up on my 250, on my 450 i never even think about it. Also, if I am hitting a jump that is directly out of a corner and the bike is a bit leaned over when i take off....it seems to not kick out so bad. Just my observance as I have only been on my 450 for 4 rides now.

Well, I have to say, I am still on the edge either way. I am still looking at money more than anything. Because I do know that you will gain 2 things with a 4 stroke. First, Cornering is smoother and you will get out faster. Second, I followed Lawdog the other day over a jump that I can do, but it takes all my bike has to make it from the outside. I followed him on the inside line and he cleared it with ease, and I about ate it. I couldn't get the power up to where I needed to make the whole jump. It is a wide open 3rd gear jump, and I came up way short and sideways since I was hitting it from an angle. Now, you will loose two things with getting a 4 stroke. First, ease of working on, I don't think anyone will disagree that a 2 stroker is easy to get down and dirty with. Second, again back to price. I can buy 2 2 strokers for the same price as 1 4 stroker. So weigh your options, and be happy with which ever way you go.

Funny, I'm actually making the change from 4-strokes back to two...
Thumpers are fun bikes because they deliver their power in a predictable and smooth fashion. That won't take too much adjusting. You'll have to adjust your riding style somewhat to the increased compression braking of the 4-stroke engine; mainly for jumping. Throttle on all the way until you're off the jump. I had a hard time adjusting to the way my YZF turns (feels like a tank in tight turns), but that shouldn't be nearly as bad on your RMZ as on my '01 YZF. Don't forget to keep the oil fresh and the airfilter clean, as well as check the valve clearances periodically and you should be good to go. Have fun

The most important thing is this!!!! DO NOT LET OFF ON THE THROTTLE WHILE GOIG UP THE FACE OF A JUMP!!!!!!!!! you will endo because of the compression, so it is always important to give it a little gas going on the jump. It becomes a habit after about 5th time you jump and from there, you will feel very comfortable in the air.

I know what your saying about jumping because on my 125 i'm pinned on everything and all these other riders are just half throttle it seems like to me and there just so much easier to ride. And the price is the biggest problem but the guy is willing to trade straight up with me with his 2004 rmz250 and my 2002 yz125 because he can't figure out the jetting and can't get the jetting dialed in right and because it need new clutch plates soon so i'm getting it because thats a hell of a deal. And the bike has a complete FMF Factory 4 exhaust system, pro taper bars and thats it.
