2 stroke or 4 stroke

I think I am going to get a 250 dirtbike instead of the 450 but I wasn't sureif I should get a 250 2 stroke or 250 4 stroke I want to be able to get up sand dunes but I also want to be able to ride rough tracks. Would you get the 2 stroke or 4 stroke? I am 5'10 and weigh 125lbs if that matters.

 

Matters on where you live. Registration and ride times for 2smokes are heavily regulated in some states.... like CA.

You also need to check on restrictions for closed course competition use.

New 2smokes are classified this way and that alone can keep you from being able to ride on anything but a track.

2smokes are heavy maintenance vehicles to keep them in top shape, 4 stroke SOUNDS like a bigger maintenance item, in fact they are lower maintenance than a 2stroke...
(Guarantee others will dispute this)

 

I ride my yz450f in tight woods/single track. Its a bit much to handle tbh but much more tameable with a some modifications. Great on mx course though.

Havent ridden a 2 stroke to have a comparison

 

2 stroke is always the correct answer, but I'm partial to 2 strokes because that's pretty much all there was back when I was a kid and got into riding. They're lighter and more nimble (so less rider fatigue), and IMO just more fun to ride, and while you may have to rebuild the top end more frequently, the cost isn't going to put you in the poor house. The upside for 4 strokes are they run smoother, have a less violent powerband and less frequent maintenance, but on the down side they're heavier and and have a less violent powerband, and when you do have to rebuild the top end, be ready to fork over some serious cabbage.

I have three bikes currently, one 4 stroke and two 2 strokes and the 2 strokes are the ones that I enjoy riding the most. If you're concerned about a 250 being a bit underpowered (based on your weight, I don't think it will be a problem - a 250 will haul your 125 LB frame around with no issues), you could always get a 300 (KTM/Husky or Beta). I'm 5'9" 185 LBS and have a KTM 250 SX, which is awesome on the track, but not much good for anything else because the suspension is so stiff. My enduro/trail/desert bikes are a KTM 300 XC-W TPI and a KTM 350 XCF-W (w/ Rekluse clutch which is great for preventing low RPM flameouts) and both are a blast to ride, but the 300 is my absolute fave. If I could have only one bike, it would be the 300 smoker hands down.

 

4 strokes suck.

2 smoker all the way!!!!!!!!!!!!!!!

 

2 stroke all day.

Love the 2-strokes. The simplicity, the smell and the power delivery. Its all I've ever ridden. I had a 04 CR250 that I re-piped, re-geared and put a twist top Keihin carb on it to make it a woods bike in Western Washington State. I also have a CR500 garage queen, the only bike I still have.

The power delivery is different. The question you asked can only really be answered by you. Some like light switch power, other dont, some like engine braking...etc.

 

I've only ever owned 4-strokes, but i've ridden friends 2-strokes on the track and in the woods. the 2smokers are more appealing to me in theory, but the 4 strokes consistent power delivery has been better for my woods riding. You say you wanna ride sand dunes and track, so i vote 2 stroke all day. For a woods bike, 4 stroke hands down.

 

4 strokes are easier to ride in the woods but 2 strokes are far more capable. Count the number of 2t vs 4t at Erzberg, one of the most difficult extreme enduros there is, actually pick any enduro, 2ts far out number 4ts, often 5:1.

 

2 stroke is also lighter weight to throw around too.....just food for thought if that is an issue.

 

Personally, 450 4 stroke. I could ride my klr650 through some trails with ease Im sure a 450 wont be to bad. I am 6’ and 300lbs so it makes a diff, but Id go with the 450.

 

I vote either the 250 2 stroke, or 450 4 stroke
