i am looking to buya 2stroker but have had alot of conflicting info from the people ive spoken to, "dont touch suzuki or kawasaki, they're made cheap" "cr250s are only good for motorcross, if u dont ride them in the powerband constantly u'l foul plugs". etc. can i have your opinions please, looks like im going to need more info. cheers. jimmy

thats the first time i have ever hear that if you dont ride in power band that it foul the plugs . who ever told this must be a right know all because i have got a kawasaki kdx and never had any prbs with itand think it just comes down to what you like at the end of the dae

"suzuki and kawasaki are made very cheaply" I wouldnt believe that for a minute, sounds liek someone with a preferance and they are only making up stories to get you to look away from the other options, But I do hear KTM are a good bike these days too, so dont drop them out the moto-x option

RMs and KXs both tend to have more little bits breaking than CRs/YZs, but they are still good bikes. The 2004-2008 RMs are very good, and the KXs aren't bad either. I own a 2007 KX250 and it's been fine.
It more comes down to how they've been looked after than the specific brand when looking at 2nd hand dirt bikes. A neglected motocross bike will be a money pit, so you've got to be a bit careful when buying one.
2003-2007 CRs have pretty weak motors (although they can be improved with some mods), but 2001/2002 were very very good.Really depends what year bikes you're looking at for any specific advice about different models.
Fouling plugs isn't to much of an issue unless your idling or at low revs for an extended amount of time. Depends what you're going to be doing with it.
Keep in mind that 250 2 strokes are very fast bikes, so if you have no experience with off road bikes they may not be the best option.

No bike will foul plugs unless jetted incorrectly. Yes 250s 2 strokes are fast Great all round bikes. I also agree about suzuki, also their bike technology in the two strokes was always a few years behind

Suzuki RGV 250 or RG500 engines {both road bikes} are still the cause of wet dreams for any true twostroke fan mate.

thanks guys, this is all good stuff. sorry i should've mentioned im looking at year 2000 onward and between $3000 and $4000. the bike will be for mostly river riding and trail rides, ive had an xr280 then an rmz250 and sometimes ride my mates klx450, so the power shouldnt be an issue, plus i prefer a bike to scare me. . whats the difference between mx 2 stroke and enduro 2 stroke! since ive never owned a 2 stroke i dont know much about them yet. cheers

i have been looking at gas gas and ktm as well, but havent heard alot about them except for that gas gas are cheap to fix.

heavier flywheel on enduro bikes generally. I think you get more torque for the trails

if your heading that way,have a look at a tm,very nice to ride.

For trail riding I'd go RM/YZ. From personal experience they seem to have the best suited engines for that sort of stuff (lots of low down power). KX and CRs like to be ridden hard all the time. That's just my opinion though.
The Euro bikes (KTM, GasGas, Husaberg, Husky etc) are very good woods bikes, and they still develop the 2 stroke engines unlike Japan. Not sure if you'd get a decent one for 3-4K though! I don't know what the older ones are like.
4K will get you a good 06ish RM250 which would be ideal. Yamahas seem to go for a bit more money, but there are still some good deals around if you keep an eye out.

i recently sold an 06 CR250 for $4k, new plastics / graphics, top and bottom rebuild about 30 hours ago, along with all new gearbox bearings, clutch basket, fibres, springs, fmf pipe & muffler, boyesen reeds, good tyres, fresh chain & sprockets.
yada yda yada mint-
it sat on trademe for a while with bugger all nibbles.there are deals to be got at the moment if you find a motivated seller, because nothing else is selling

heavier flywheel means less agressive powerband doesnt it! so for example a kdx vs kx have roughly the same amount of power but its dished out differently!does that sound right!
mrfxit,

yep thats right
Takes more time to spin up a heavier flywheel = slower revving instead of SNAP revving through out the rev range = more controllable revs Snap revving & light flywheel = fast with no load, but the more load you put on makes them gutless really fast because theres no flywheel momentium weight to keep the revs going for that little bit longer
Can also mean the engine is a little bit harder to slow down, so a light/heavy flywheel swings both ways in the end result. just depends on which is more desirable, fast revving or being able to maintain revs better.
Exact same for ANY engine

heavier flywheel means better traction and hill climbing ability.Enduro bikes usually get further up hills than mx bikes through smoother power delivery.

in my own personal experiance ask the seller to remove the expansion chamber so you can inspect the barrel for any scoring or marks on the piston this could be the difference between buying a lemon or bike that you can actually ride and not have trouble with.

well thats a new one. cheers

It's a hassle, but well worth it. Offer $10 to pull it off but a refund if you DO buy it.

l agree the kawasaki kdx is a dame good bike

To add to the comments above about flywheel weights, you will find a heavier flywheel is also a godsend when you are doing a balancing act across a log bridge or down a rocky creekbed or similar. An mx bike will stall very very eisily, where an enduro will not. At the other end of the scale, a farm bike, will scale mountains at idle.
Stalling, when tyhere is no hope of getting a foot on the ground is never a good thing.
