What is the difference in yamaha's yz 250 and the ttr250?

 

yz is a two stroke mx bike

ttr250 is a four stroke trail bike

 

ok that makes since, i was wondering because i found a couple online that were both going for 1,800. which would you say would be the better bike?

 

the 2 stroke is definitly goin to be faster and the yz is going to have a different suspension than the ttr....basicly the ttr is set up for trails and the yz is set up for racing in their stock forms

 

2 strokes are very unreliable between fouling spark plugs and top end jobs. i would go with the 4 stroke. but that is just me.

 

top end rebuilds on a 2stroke are one of the easiest jobs on a bike you could have a new piston and rings put in in about 2 hours...as long as 2 stroke are treated with what they need they will last

About 30 horsepower.

The two stroke YZ is for racing, the four stroke TTR is for putting around camp on. The two stroke is easier starting, requires less maintenance (no valve adjustments), is much lighter, has much better handling and suspension, and is a lot more fun to ride. Basically there is no comparison between those two bikes; they are totally different.

 

but every body isnt mechanichly inclined to do a top end job. and no matter how good you take care of your two stroke and how good you mix your gas you are going to foul up spark plugs. and it all ways seems to happen when you are around a truck or a spark plug.

i meant to say are not around a truck or spark plug!
my bad

 

If a two stroke is jetted correctly it shouldn't foul spark plugs. We've owned a couple of TTRs, and four two stroke bikes in the last few years. My youngest son has a KTM 65 SX that is on its third rear tire and still has the original spark plug. My oldest son is on what must be his eigth rear tire at this point. He has raced two full desert seasons on his KTM 300 XC, which is about 2000 racing miles, and he is still on his original top end, and we have changed the plug one time just for preventative maintenance before one of the nationals he raced in. He has never had a DNF in two years of racing his two stroke. And the racing miles he has accumulated is really only half the actual miles if you include practice time. 4000 miles on the OEM top end isn't too bad, and his 300 (289cc) two stroke is still fast enough to beat my 530 (510cc) four stroke in a drag race.
