The RM250 is a two stroke, the RMZ250 is a fourstroke. Motocross used to be all about the two strokes, high whiny weed eater sounding motors, but now Suzuki, Honda, Yamaha, etc. are all making fourstrokes, deep "thumper" sounding motors that have a high performance compared to where the fourstrokes were back in the 90's and early, really sluggish and heavy, usually made for enduro or trail riding only. Anyways, a 250 twostroke is about equal to a 400-450 fourstroke. A 250 fourstroke is about equal to a 125 two stroke, so the fourstrokes have to be about twice as big to make about the same power. In Supercross, there are two levels, the 250cc and 125cc levels. 450 fourstrokes and 250 twostrokes race against eachother and 125 twostrokes and 250 fourstrokes race together. So, in your case, the RM250 is equal to a 450 fourstroke...much larger than a 250 fourstroke like the RMZ, but people are starting to get fourstrokes because they are in some cases easier to maintain, quieter, and don't pollute as much. So twostrokes are becoming cheaper because there is less market for them, but if you are serious about racing, fourstrokes are where it's at. Hope this helps.

As stated, the RMZ is the four stroke race bike and the RM is the two stroke one.
The RMZ is less powerful that the RM. The RMZ will require more maintenance to be kept up, be more expensive to rebuild, and will need rebuilding on much the same schedule, if not sooner than the two stroke.
Simply put, the four stroke has more moving parts, revs up higher, and because of this wears out on much the same schedule as a two stroke. Due of it's popularity with the "If Ricky/Bubba/Chad rides one then I have to ride one too" crowd, parts are at a premium.
If you put an aftermarket pipe on the thumper, and re-jet to match then it's not only MUCH louder than a two stroke (and noise is killing the sport my little cherubs) and is every bit as bad in the pollution department.
So. let's re-cap. Displacement for displacement, the four stroke is less powerful, requires more and more expensive maintenance, makes more noise, pollutes more and is more expensive initially.

If i were you i would go with the 250. You would like the 125 and get use to it but than your just going to want bigger. So yeah go with the 250 so you can grow into it and enjoy it for a long time.

the rm250 is a 2 stroke, the rmz a 4 stroke, the 2 stoke has twice the power and much cheaper to mantian, the rmz is made to race against rm125. it takes twice the cc of a 4 stroke to compete against a 2 stroke.
