thinking of getting a wr450f

112 posts in this topic

Hi,

First new thread so please be tolerant if I made this in the wrong section

I currently have a '06 yz250 but I don't like the maintainence and I cant seem to get my balance on it, probably having something to do with that I feel to tall for the bike ( I'm around 6ft 2)

And I was thinking of changing to a 2015 wr450. Now I mainly ride at mx tracks ( not competitively) and do a little bit of enduro here and there. Now the things I will probably need to change are the exhaust , for performance, and do something for the suspension ( I'm around 115kg with gear ) any ideas as far as what to do for suspension, I've never looked into it before.

So what else would I have to change to make it more of a mx bike? I would want to remove the battery and all the lights ( will a stock yz450f front race plate fit in place of the light?) but I can't find any information on how to easily remove it all.

I pretty much want to end up with a mx bike with an enduro engine.

Any thoughts and advice is appreciated

Thanks,

Mc

Are talking YZ250 or 250F?

 

Not sure what you mean by ' I don't like the maintenece' ; mixing oil maybe?

 

What do you mean ' an mx bike with an enduro engine'?   Do you mean softer power?  Wider gears ratios? (you do not want that for mx).

 

If you are going to pull off the battery and lights, why not buy a YZ to begin with. Is it the estart?

 

Your questions are very confusing.

It's not the e-start, he wants to pull the battery.

Why not start out with a YZ450 and mellow it out with a heavier flywheel and some mapping changes?

Many threads on this topic and it seems to be either an expensive or never-ending project. At 115kg you defnitely need much heavier springs to achieve proper sag and balanced handling.

 

I have a YZ250 two and four stroke and a WR450. I could not even come close to making the 450 a hybrid bike that you speak of without spending a ton of money and still dealing with its short comings specifically weight.

 

Not to hijack your own thread but have you considered a KTM offering?

Sounds like you ride the YZ250 2 stroke? But I'm sorry to say if your coming off that and like MX you should be looking at the YZ450. I love the WR but its not a track bike. WR stands for wide ratio trans. Not good for the track. There is to much to do to get it to be fun on the track. The last thing you want to have is a bike that your fighting with the whole time. Not sure about down under but here in the states most enduro racers are on YZ's if there on a Yamaha 's.

Its very easy to lop 20+ pounds off a WR450F by removing the starter, battery, kickstand and a bunch of other stuff that Yamaha has plastered onto it.  I started a post on this very thread.  Unfortunately a bunch of idiots messed it up, so I stopped posting in it. 

 

As far as suspension goes, the forks are standard SSS.   So do to them what you would do to any Yamaha SSS fork.

 

In the rear, the 2012+ WR shock has a 10mm shorter shock shaft, a smaller comp adjuster piston and the linkage is tuned for trail riding, not MX.   I bought a used YZ shock and linkage on eBay for $160 and rebuilt and revalved the shock myself.   I have a thread for that in the suspension forum.  

 

I also installed an 08 YZ exhaust cam.

 

These mods dramatically improve the WR.  Stock its a good play bike.  Its an awesome base to start building a focused bike because its got all the right pieces (engine, frame, suspension) and Yamaha parts are very readily available and bolt right on for the most part.  I'd go for it.   Unless you want a YZ specifically, you won't be sorry.

So, now your mods would make the WR into a good MX bike as well.

You are hopelessly clueless. :facepalm:

YZ250F frame + Yamaha suspension + older YZ450F engine = good all round bike.  With some mods, turn it into anything you want.  SM, DS, woods, desert and hobby MX bike.  

 

OP already stated that he doesn't want a YZ.  A modded WR is the next best thing.  Drop 20+ pounds, tune the engine and tweak the suspension.  Its not that difficult.

 

I've never seen so many people so opposed to moding something in all my life.   A stock bike is a starting point, nothing more.  If you want to ride a stock bike, great.   But I can't help but notice that the only place you and some others on this forum are riding your stock bike is on roads.   Ironically, the WR450F was never designed to be a DS bike.  In stock form its a heavy trail bike.   If you like that, great.  But some of us want to use WRs for other uses and we mod them.  Get over it.  Or at the very least, stop criticizing people who actually do something with their bike.

You have a reading comprehension issue (amongst others).  He did not state that he does not want a YZ450.

 

I have no problem with modding bikes.  You really don't seem to be able to pull yourself away from your specific bike and take a look at this objectively.  It would really seem to make more sense to start off with the MX platform bike and make the adjustments to it, personnel diffences aside, wouldn't you agree.  I am not saying it can't be done, but again, objectively, it seems like it would make more sense. :thumbsup:

You have got to be kidding, that is the funniest statement I have read on here in a long time.  I am sorry, I was trying to be civil but you are a complete &%$#@!.  Have you seen the videos of my riding?  I &%$#@!ing guarantee you I ride more technical trails then you.  By a looooooong shot :facepalm:  :facepalm:

Which is why I ended my advice to him with

 

Unless you want a YZ specifically, you won't be sorry.

 

Some people want a wide range transmission and a tamer engine.  They don't want a YZ.  A WR suits them better.  If that is the case, my advice applies.

 

I spoke about my bike because it has most of the stuff he is going to need to do.  Weight reduction, suspension and maybe engine mods.  Are there any other examples on this forum that he could use as a guide ?

But that wide range transmission will not give the OP the best solution on an MX track.  The lighter flywheel will tame the engine and a gearing change can address the trany.  Some simple changes to a good MX platform bike. :thumbsup:

Yesterday, Tuesday, November 4th.  Several inches of snow in the area on the weekend that has since fully melted in the sun exposed areas and ran into the valleys or not melted at all in the trees.  25 miles of ice, mud, snow and melted snow on tight un maintained single track with several long climbs and more slippery , snotty logs than I care to remember.  5,000 feet of elevation gain/loss.

 

When the ground freezes I'll swap on the studded tires and tackle it again.

:thumbsup:   I would like to see the technical trails you talk about though.  Single track isn't technical in and of itself.  They are just the best trails to ride :ride:

So ?  OP understands a WR has a Wide Ratio transmission.  Doesn't sound like he is racing.  Maybe he wants it for some other reason.  Lets not forget that a prominent magazine did a (really poor) attempt at turning a WR into an MX bike.  Its not optimal, of course, but it can be done and ... it might be fun !

Agreed, it can be done.  We are just approaching it from a different angle :thumbsup:

Sorry, but that is childs play compared to riding where there is zero traction.   Ever ride on ice ?  Ever ride in snow that covers the logs so you don't see them before you hit them ?  How about climbs where you turn every 20 feet and can't see the terrain around the turn or you have to slow to 1 MPH to get through the trees that are 1" wider than your bars ?

 

You wouldn't criticize my 12/51 gearing if you rode with me.

BTW, my WR rocked on that ride.  I was amazed at the traction it had.  That KTM 200XC was slipping all over the place.  My WR was hooking up really well.  Not sure if it was the YZ linkage or the shock revalve or the knobby knifed IRC M5B, but it worked.

 

I'm the only one in our group left riding a 4T.  The other guys are beginning to see why I ride one.  Its telling when I'm at the top of the hill waiting and they are revving and clutching trying to make it up.

      does anyone know if a 1997 Yamaha WR250z is legal on your L's/LAMS?
    • By owainyz03
      Hey folks,
      I'm delighted to be back in the YZ 2 stroke forum after a bit of an absence. I used to own a 03 YZ 125 which always regret selling. I currently own a 2011 yz 250f and owned a 03 rm 125 until recently when I sold it to a friend. Only a few weeks later I got the 2 stroke itch and began looking for a 06+ YZ 125, after being blown away by the SSS suspension on the 250f. A few came and went that I missed out on but finally one popped up. Advertised as a 2007 yz 125 (vin checks as a 06) priced at  2500 Euro. The usual BS advertised was on the ad "good tires only one ride, chain and sprockets good etc " Arrived down and found the chain and sprockets absolutely shot, tires were worn, Leaky fork seals(looked like new oil?) rear fender broken few bits and pieces. Talked him down to 2200 euro and was happy enough with that. Picked it up on friday on my way home from college and started ripping it apart. And that's where things go down hill 
      Found the air filter in a shocking state (see pics) which caused a major groan.... still at least its a 2 stroke. From looking in the exhaust and intake ports I could still see crosshatching very clearly, unfortunately I didn't have time to rip the cylinder off yet. Counter shaft seal appears to be weeping so that will get replaced, also isn't there an issue with 06 shift stopper or something? It does have unbreakable levers which is one of the few plus's
      All of the bearings will be inspected and replaced if necessary, new top end most likely, new bars, grips, tires, fork seals, chain and sprockets, air filter, restyle plastics more than likely and whatever else I uncover 
      Keep in mind this will be a slow build as I'm in college 5 days a week.
      Now some pics
