I've been riding for a decade. I'm 30 yrs old, waiver between 210-230lbs. In Good shape. I ride an ATK605 and ride trails and desert mostly. But I want to get into riding motocross. Not competition but just for fun.

I dont need a 450.. I know that.. but should I go 125cc 2smoke? 250cc 2smoke? 250 4t? I want to be able to fix the bike if I need. I am decent with mechanics but not swimming in $. I want to have fun but dont need a new bike. I've been seeing mid 90s to early 2000s 2strokes that are in my budget.

Ide love some input. (Picture of my ATK605 for attention)

You need to say the budget you have, bro.

But if you are looking into the 2000-2005 bikes i would wager for 250 2-stroke. early 4-strokes were PIA. If you are looking into 90's bikes i would not look there at all if you don't have money for full proper restoration.

Long story short: If you are really fit dude with big cojones you should buy 250 2-stroke and have a blast.

'06 & up YZ250.

Yepp, for that budget a 250 2 stroke. Buy one, do a top end, check everything, buy ten air filters and have fun for the next 70 hours. If it hits to hard add a flywheel weight.

Get a 3 stroke!

Agree on a 2K budget I’d opt for a 250 2 stroke.

If you take money out of the equation I have found I prefer a 2 stroke for woods/off road riding, and a 4 stroke for MX. So in a perfect world I’d have both and one set up for each!

YZ250 sounds right up your alley.

2/14/2020 6:07 AM

If you weigh more than 210 pounds and have riding experience I would get a 450.

2/14/2020 6:17 AM

Another vote YZ250.

Tough to find for 2k but agree, yz 250 all day

For that budget a yz or rm two stroke, I would not even mess with buying any used four stroke that is older and that cheap unless you plan on going thru the entire bike and spending lot of money at some point.

I ride a YZ250 now, and I've had plenty of 2-stroke 250s as well as a few 450 thumpers. I love the YZ250. Most versatile bike I've had.

BUT....if you are coming off a Rotax powered big bore 4-stroke, the 2-stroke is going to feel extremely foreign to you. I'm not sure you will enjoy it like seasoned 2-stroke riders do.
So in terms of your comfort and confidence transitioning to MX from trail riding, I'd have to say the 250 4T might be the better choice.

The problem is that most 250 thumpers in your budget are going to be thrashed and engine repairs can be expensive. But if you are patient and keep your ear to the ground, you can still find some gems out there.

If you do get the 2-stroke, invest in a flywheel weight. It'll make the transition from the 605 a little easier.

Sounds like a pretty resounding point for a yz250 2smoke. I will keep you all updated on my pick.

|

2/14/2020 8:12 AM

Just make sure you have that 2k in hand and are ready to jump if an 05 or newer pops up. Most people think and 05ish bike is worth the same as a say,,,,, a 2015ish bike.

I'd go 04 or earlier or 06 or later. 05 was the first year aluminum frame but had non sss forks. The steel frames worked better with the old style forks. (IMO) 06 and up have the sss forks.

I hear you. Excuse my ignorance, but what will the flywheel weight do for me?

Those forks were still really good though. I took the set of 05 forks I had on my 98 and threw them on the 05 I bought from you because they were already setup for me by N2Dirt and they were just as good as the 06+ forks.

OP, even if you find an 05 and don't like the forks, I do see 06+ forks pop up for sale around the $300 mark.

Basically makes the power more 4 stroke like. Most guys love them. I've never ridden with them before, but I enjoy the power of a 250 smoker just the way it is.

Have you ever ridden a modern 2 stroke 250 motocross bike? Most younger people who have ridden 4 strokes there entire life don't like the 'abruptness' of a 2 stroke powerband.
I don't have a problem with it, but I've ridden 2 strokes all my life.

YZ250’s are the best. Versatile, easy to work on, unlimited parts availability. They’re just a good bike.

Good luck finding a used one in the 2k range. They tend to hold value, with most sellers looking for around 3k for even 05’s and 06’s with hundreds of hours. Certainly not as bad as used KTM’s, but still ridiculous.

It will made inertia to the crank. What that does is it makes the engine rev slower but makes it feel more torquey and tractable. It also makes it harder to stall.

In other words, it makes the bike easier to ride, especially for a rider coming from the 4 stroke world.

2k for a good YZ is gonna be tough, esp in Cali. Good luck though.

Don't pass up a good CR or RM 250.
The RM's have the hardest hitting power of the three, but their ability to carve a corner is excellent.
The 02+ CR250's have arguably the best chassis and have a milder feeling powerband with lots of top-end pull when you rev them. Not as snappy as the YZ or RM, but coming from a big thumper that might not be a bad thing.

Gonna throw in my vote for an early 2000's KTM 300. Very tractable power, doesn't hit like a 250, but plenty of sing. Adding a flywheel weight not needed. Most used ones are going to be ex-vet bikes, so they may not be as thrashed as a 250 mxer.

Won't be as sharp of a carver as a YZ or RM, but coming off that ATK you'll think it's a surgical scalpel.
