Putting my ego aside,stepping down

Kudos on considering something other than a 450. Do it.

I get a kick out of the fat vet macho men who dismiss the thought of riding anything but a built 450.  It's hilarious.

pshh

my mom didn't raise no bitch

I’m typing this in a cervical collar after breaking my C6. I just got my first 450 and I’m pretty fast but the power is just different. When you crack the throttle on a 450 there is zero delay. My YZ250 and MC350 would have enough of a differential between throttle and launch to provide some margin. The RMZ450 so sharp and pointed that it feels like you’re defying physics the way it moves. I know that sounds maybe dramatic but I’ve never experienced anything like it in the dirt. 

I would do anything for an RMZ325. 

I rode a 25 KX250f the week before breaking it back to back with the 450. Maybe some people are different but that bike truly did not have enough power. I was laughing while riding it. I do so closely resonate with your story and share the same feelings.

Does anyone know the best way to add some mellow back to a 450? Bigger countershaft sprocket? I haven’t even removed my backfire screen and have the bike tuned down mellow😂

I'm 63, and usually ride a Yz125.

When Yamaha had a demo day, I tried the 250 2 stroke, and the 450.

The 450 was more rideable to me.  I'm sure I could get used to it, but the 250 2 stroke scared the crap out of me!  It was simply explosive, where the 450 was super fast but controllable.

If you're trying to tame it down a bit, give a 125 a good chance.  They're incredibly fun, and plenty fast, for me anyway.

That said, I may give a 250F a try for my next bike.

What brand are you leaning toward?

Try out a Stark Varg before you buy anything. Fully customizable power. Don’t forget to get a referral before you buy. You will thank me later. 

Your yz125 modded is Real quick & strong. I agree a 2st 250 can be a violent burst upsetting the chassis hitting deep holes etc.  You get away with swamps on a 125 a 250 will punish you. I stopped riding 250 2-st because of my back you sit more .  91 cr250 has a great feel handling & the motor is amazing. If your into old bikes that’s a good one.  250f,s are too hvy the op has injuries not a good bike unless he gets healed up .   

The 250 2t needs a flywheel weight to smooth it out.

As I have got older, I am thinking of a 250F also. I rode my friends YZ250 2-stroke and it's a blast, but wears me out quickly. I've dropped 44 lbs, but still a bit over 200 lbs (still losing weight though) and think a 250F would pull me now just fine. I love a 450 in the right place, but they are a handful. This is coming from a former CR500 and KX500 rider.

I,m the opposite reg wt 172 down to 148-150.  Fight with insurance for a month to get injections. I did pt on my own a ton of stretching , epson salt baths hot& cold , speed sit-ups at 7pm . I pig out before bed & still lost wt. super busy doing stuff too. I think it sped my metabolism up.  I,m eating like a horse I only got up to 155.   The lt wt Really made a difference on the bike the little riding I did. Same gate drop 30,50+ I think I ran down & passed most of the 30+ guys on new 250f& 450 on a clay track. 50+ is real fast.    And I skipped practice I didn’t even look at the track. Haha .  I,m sticking with a 125 

THIS!
