2 stroke vs 4 stroke engine lifespan

And here we go again folks

AHAHAH so true...the battle will never stop... people just dont get that its a preference.. if you can be bothered with a 2t then go for.. I LOVE THE FUCKORS ITS WHY I OWN 2 OF EM... soon to be ONE!! but if your not familiar with shiz and just wanna play get a lumpy 4 batt. IMO no hate to 4t owners... i love 4t's aswell its why i OWN 3

got a '06 KTM 450 EXC, got it at 80 hours and just coming up to 300 hours. ridden pretty easy on trail rides.

up till now only regular maintenance; oil, air filters and valve adjustments every 30-50 hours which i do myself.

last adjustment the intake valves had no adjustment left which is a known thing on this model.

i pick it up tomorrow and i'll be $2k poorer. and thats with me buying the valves and piston off ebay and them doing a few other little bits.

sounds a lot but $2k for 4.5 years and 220 hours worth of fun is probably a pretty good investment.

but gotta admit i was thinking about a 2 stroke or a reliable jap 450 when they quoted $2k just coz the intake valves were gone.

450exc's are fuckn work horses... i love those bikes!! should have never sold my 525. Sigh! but now i own a cr500 so fuck you! ahahah jk jk

Two ticks mate :-)

You're wearing that picture out mate. Unlike the bikes in it.

This man speaks the truth!

Give it up, Crasher - haven't you twigged that Stylo doesn't actually own any bikes at all and is only trolling?
The guy's a spankcarrot apartment-dwelling eedjit who's found a bunch of pictures of some vmx 2ts.

On to the subject in hand - do I get the feeling that 4ts are getting higher in compression and performance and 2ts have followed suit?
I'm way behind the curve but when I get off my ancient 2-wheel sofa and get on my mate's CRF450 it feels like it's gonna blow at any moment.

To me the elephant in the room is the gradual change from a 250 being a gutless starter bike to a 250 being a respectable dirt weapon (2t or 4t) - I reckon it was the MX crowd wringing every last drop out of the cc's available that did it.
Keeping in mind that F1 cars are, so I hear, about 2.5litres- the new KTM MX bikes being 150cc size isn't that surprising.


Everything is being pushed to it's limits,2t and4t, as an earlier poster said, it's getting to be purely a matter of personal taste these days.


I've got an old fat thumper and I would LOVE a 2t as well.
Also I'm teaching a skinny runt how to ride and I'd like a trials-type 2t small bike for her



Oh fuck it, I just want a double garage full of bikes

by this post i do not think you have really followed motocross for a while, 250cc racing was the preimer class from the mid to late 80's on, the 450's only came in as four strokes were allowed a higher limit to race in this class from the late 90's, again the 125's was seen as the feeder class and thier limit was 250cc for the four strokes,

the four strokes rev a shit load higher than the 2 stroke machines they replaced,

250cc trail bikes are still learners bikes, as they have always been, we do not really have the big bore 4 stroke dirtbikes anymore (TT500, XR600 etc) due to the fact that 450cc bikes put out way more horsepower than most people can use now,
(I know there are a few euro exceptions, but these are getting smaller as well)

My 2011 ktm 350 blew up last sunday, fucked cams, cam bridge, head, piston and cylinder $4100, and yep im going back to a 2T...

Fark, that's not good reading...

I've had a few issues with mine, currently doesn't like shifting from 1st to 2nd, but I put that down to the monkey dealer mechanic who had the gearbox apart in the last recall. Being an early production bike, I was expecting a few teething problems but while I think KTM know how to put an engine together, I'm far more concerned about the work done under factory recall.
