I've built and ridden a few XRR's and now I'm finishing up a buildup of a CRF450X, so I am marginally able to answer your question.

The XRR is more of a dual sport friendly ride. It has relatively conservative geometry, a torquey motor that John Deer could be embarrassed by, and durability that would make an anvil jealous.

The CRF is a crisper handling, much more hard edged machine. Handles great, the spring rates much better from the factory for bigger riders, but the valving is sort of wonky for me. For a 450, it pulls hard.

The drawback for both is a 5 speed box. If either had a six speed, I'd be all over it.

I can say a lot more about them, but if your offroad bias is way on the dirt side, the CRF is a really fun machine. It won't carry much, and will never last as long as an XR, but is about 20lbs lighter, is plenty fast (but nowhere near the torque), and is also easy to work on. If you prefer loping along and ignoring shifts and such, the XRR is hard to ignore. I loved my XR650R's.

So, I'm trying my hand on the CRF, and we'll see how it does. Thus far, I like it - I miss the XRR, but the dirt manners on the CRF are where I'm looking these days anyway.

Thanks for the input. I think Ill stay with the XRR for now, I hear too many people say they miss theirs or wish they had kept it. I do love the low end power/torque and ability to be able to ride the bike all day in many different terrains. Maybe I should just look for a 250 off road bike to compliment it instead of replacing it.

the expansion tank from back of 250 X is about 400 ml
so it's not enough as an reserve fuel tank

try to buy a bigger fuel tank with a bigger reserve quantity


what about mousse ?
do you use it ?
is it hard to install ???
is far better that tubes???

it will be great to mount it on my bike....no flat tire worry no more.......

the CRF 450 X is about 113 kg empty
the XR 650 R is about 120 kg or more

the XR feels a little bit heavier but the seat height is lower

anyway I love my CRF 450 X...much more than a XR 650 R wich is also a great bike

waw

I am very surprised,I knew that the italians from HM (kind of Honda Italy) are doing some XR 650 R with electric starter, but I did not know that they are making alot of CRF 450/250 (X or R model) versions with dual sport kit on them.
I will give you the links:

http://www.hondaitalia.com/moto/default.html

http://www.hmmoto.it/ita/default.asp

check out the range of 450 X/R and 250 X/R in enduro tab

there is also a version of 490 X '07 or 500 X '08

I AM SURPRISED AND CONFUSED

I HOPE MY BIKE IS NOT MADE IN ITALY (and I'm pretty sure it isn't)

of course the price is pretty big.....around 10.000 euro

If you do the air box and/or exhaust you will have to rejet. I love my 06 450X! It ran for 13 hours non stop during the Baja 500. My motor is stock,(at the moment), but I'm running a ProCircuit T4 exhaust and my airbox is opened up. If you are not running a hotter cam, like the one in the R model, you won't see any benefit to the pink wire mod. Check out crfsonly.com for all the info you need.

Take all the emission crap off it.
I put my CRF 450R muffler(way lighter) on my X and jetted it up as well it gives it a bit more power.I also cut the pink wire but i'm not sure if it helped ,it gives a few extra revs up top.
Stock here in Australia they come with a suspension imbalance as the front is way too soft on compression and the rebound is way fast as well.
I think a quart is equal to 850mm of oil as well.

Mihai,

Hello! The CRF450X is very popular in the USA,... but mostly for Motorcross Racers, Desert Riders & Weekend Trail Riders. Dual Sporters (like on this website) tend to buy bikes that are already street legal with lights & horn(Yes,... big suprise,... Lazy Americans )

~You cannot title the bike for street use in some states if it was titled offroad only (North Carolina for Example),... Even if you have lights & horn!!!

People who own CRF450X's probably spend more time riding then posting pics & threads. You have a great machine. Enjoy it!

L8r,

thanks for the advice, now in Romania is winter...I cannot ride it anymore, I like it alot and I can hardly wait for springtime.

actually I will manage to register it without any modifications (maybe a mirror and a stoplight)

I ride it on trails most of the time, I do not use it for racing, it's too tall for woods...where the KTM is the best.

I think it's a good bike for desert racing and suitable for me.

diggin up an old thread.
I've got a crf450 (2000) in the garage and i'm wondering if anyone knows where i could get a used part exhaust.
Mine's custom but makes WAY too much noise.

or if anyone has one lying around
