WR450 F or CRF450 X

"I am a total novice when it comes to trail riding so would be interested in your opinions".

I think this sort of answers your question. If I was a total novice then there would be no way that I'd have a 450. If you buy from a dealer that cares then they should explain this to you.

The WR is a fantastic machine and is well recommended and well proven. You won't be disadvantaged for trail riding having a 250. At the end of the day it does come down to the rider.

Happy shopping.

Yes 450 4t enduro machines. 40-45 hp is the realm of the 250 2t MXer. I'd guess mid 30s for the 200 2t enduro bike.

05 cr250 was rated to be 64hp

Like hell it was. AFAIK the only 250 2t MXer to ever put out a stock 50hp was the 2003 KTM SX. It was nearly unrideable and they detuned it the following year.

Many who rode the old CR250 motor (mechanical PV) preferred it to the newer case reed electric PV model. Newer isn't always better.

was rated at 59hp not 64 close but not quite. proberly obtainable though with a few bolt ons.

Anyway get the wr250, you could have a go on a demo first.

That still doesn't sound right.

Its funny, I've ridden both versions of the CR and the Electric version I find much better. Its got heaps more bottom end. The only odd thing I find is that the PV can sometimes pulsate.

On a side note I found that the 02-04 version very different to the 05-06 version. From what I read on the net the 05 onwards version was the one that everyone has issues with in terms of twichy jetting etc. In saying that the only real engine difference I can tell is that the 05 onwards ones are single ring on the piston.

And in real power tests, there was a write up in DRD about a year or so back and they did a dyno on a 06 CR250 with heavier flywheel, FMF expansion chamber and from memory it put out 65hp. I'll see if I can find the article.

I give up. Quite clearly you all have 65hp CR250s. All my ones have obviously been duds.

LOL here is a review of the 05 MXers with dyno figures

You may get 65 with full on engine mods but it would be a monster.

i think we are all arguing the same arguement.

i referred to the 65hp ive seen on a uk site, which wouldve been measured at the flywheel - claimed / rated 65hp

actual dyno results will always be significantly lower, so if its doing 65 at the flywhel it probably only is doing 45 at the wheel

What he's saying is, BUY RED... You won't be dissappointed

haha, and that!

also another added bonus of the CRF-X is how upgradable it is, simply swap to CRf-R parts.

but red is good

Maybe. You must have got the ones that Suzuki Hijack and fuck with to try and make Honda look bad! LOL!!!!!!

In my opinion i think going to a 450 would be a mistake. Holding on to a 450 is like holding on to a CBR1000RR and you have to do it for a 60km loop with you son following. (If he is following 450 throw alot of dirt even if you try to be nice to it) I ride a CRF450 and around our track i think id be maybe 1 second quicker per lap on a 450 then the 250 but i could spend all day on a 250 and not feel tired but the 450 will have me beat in about 30-40min. Until you can hold a 250f at full throttle out of every corner i don't think you need a 450.

Also they are higher maintance expect the best chain money can buy to last no more then 35-40 hours

No way you lose 20 HP through a bikes drive train, the losses are far less than that of a car. If they are making 45 at the wheel then they are probably only making around 50 at the flywheel. I have ridden multiple CR250's also and there is no way any of them had near 65 HP.
