All 2st I think I need a WR300

I've always been a 125 guy, and I love my CR150, but it's getting harder and harder to run up front. We have open classes, skill based, and I'm topped out and racing against mostly 450's. I ran 3rd and 4th on the weekend, battled both races with a 350 KTM, and he pulled me out of every turn.He got me in moto 1, I got him in 2.
While flagging between motos, I watched another class similar to mine, also with a guy running a YZ144 against predominantly big bikes. He was working that thing for all it was worth, and doing well, but the 4 stroke guys, running at the same speed looked like they were out for a Sunday ride.

Which brings me to this article http://motocrossactionmag.com/bike-tests/we-build-a-full-race-husqvarna-wr300-motocross-bike

I'd read it a few years ago, and I'm starting to think this is what I need. I wonder if my aggressive riding style would work with a bike this size? I only wish they were easier to come by around here.

Think the ultimate rever / bore size is 250 its got more grunt and same size frame as 125's normally.
How about just droping a bigger motor in your frame.

And if your going big bore go macio all the power you will ever need and more!

To me the 300 was a low end monster and the 250 more of a revver.....

Thats what im saying.

So maybe I need a WR250 converted to MX. There's a super clean one for sale around here, but he wants huge money for it.

No keep an eye out for a cr250 thats already mx.
That is if you still wanted husky but those are old bikes whats your budget?

I also own a WR250- and thats such a difference- its got so much more power than the 125, but still likes to be reved to the moon (depending which exhaust has been fitted)! My brothers 300 is more a bike to cruise - not to rush at an MX race.

I came to the same conclusion with my 125/165s
The 300 can be ridden hard in the open stuff and is great there - so I think on an mx track it would be great - especially on jumps . Just takes more effort to stay on the pipe
You can run in higher gears and short change and be running similar pace to smaller bike.
It takes more holding on to but I have got used to mine . Suspension set up is also important .

250 or 300 you wouldn't go wrong

I went to a deep sandy Mx track close by and even 250 2t were getting smashed by the 450s . 125s no chance .

It's not likely I'll ever find a CR250 here, so I'd have to settle for a WR, and mod it from there. Hopefully prices come down on them around here.

In the meantime I'll keep working on the 150 trying to make it a little faster.

165 kit will make it a little bit faster

Check this one out, I think it is a really good deal:

So true.

Sir; currently riding a 125wr and a 250wr and a 300wr. The 125 is fun, The 250 is solid and will always get the job done. the 300 is gold. same as cash. torque is godlike. fear no jumpface- have a good FBF suspended CR 250 I am not using currently if you are man enough...

Not sure the 165 is best mx motor. Might be wrong but everytime I have rode my wr165 on track it just does not rev like 144 it close but just not suit for mx like my 2012 ktm 250 sx is. That the solution for mx. Also like my sons 2010 yz125 better on track than my wr165 but for single track off road wr 165 hard to beat.

I owned a WR165 and the more I rode it, the less I liked it. I don't think the problem is 165. I think the problem is WR.

Sounds expensive...

But its the beastie you want cr250 proper sorted suspension, gettit pm him lol

A 250 SX is the only orange bike I've ever ridden that I liked, the linkage rear and snappy engine made it better than the 300 which flattens out on top (I strongly dislike PDS). My wr250 with a Lectron and 2cs pipe would be up to the task but still no match for a 450 in sugar sand... a cr ignition would help. As of now it is valved for the woods it blows through the travel and I bottomed it so hard I was afraid of breaking it or me if I kept riding it on mx tracks. Although I've never ridden one I would think a wr300 with a high compression race head, a little porting, a cr ignition, PC pipe and KYB cc forks would be the ticket for you.

My 02 they put on the 50 mm full Lammy A kit suspension.... it was saweet

For reference, in Oct, 2014 I paid $3500us for 2012 wr300 with @ 10 hours, Rekluse EXP2, EE rad braces and some bar risers.
