CRF250R Must Do Mods?

I think Im going to go pick up a 16 CRF250R new this weekend. I was considering the KTM350SX, or even the 17 CRF450, but for 3 grand more, I cant justify it for what I will use it for. Mostly play riding at my home track, and occasional practice days.

Any suggestions on what to do first? I know they are slow but otherwise great bikes.
Im planning:
Full FMF 4.1 single and side panel swap
Stage 2 Hotcam
Remove Screen
Replace chain (Gold DID or Renthal)
Hour meter


What suspension work does it need to feel decent for a 195lb rider? Intermediate, vet mx, 36 yrs old. Respring shock? What can you do with the forks being air forks? Im not familiar with them.

Im going to sell my 14 150sx after riding it a few more months along side the Honda.

2018 crf250 is all new, like the 450 this year. Just something to think about.

Personally you don't need anything done to it. I have a friend racing supercross on a STOCK 250 with a pipe and suspension. And he is qualifying into the night show

If you are going to be spending ~$1,200 just to make it go faster why don't you just buy a leftover 2016 450?

If it's just play riding and practice days, a stock 250F will be plenty fast.

I saw Don from Rocket riding a CRF250, yesterday. That bike was a ROCKET. Literally.

I'd have him do whatever it is you want done.

Like I said...it WAS A ROCKET. He was roosting me on my 450.

This curmudgeon thinks you need three things to make that bike go.

1. Gas in the tank
2. Air in the tires.
3. Oil in the engine.

Really. Just ride the snot out of that thing. When it is time to modify it, you'll know what it needs or does not need.

Haha. Thanks guys. Pipe is because I want it. Some things you just want even if they don't make total sense. Ride time is key. Maybe I won't get the cam. Well see.

I can't wait that long til the 2018. I'll sell this one in a couple years max anyway. I'm in no shape to ride a 450 hard. Truth. A 250f is fun on my practice track. It's slower speed and a ltitle too tight.

Should fit this honda well maybe.

For what you are doing with it , I would do the pipe and suspension. Maybe a remap at some point but no reason to map it to run on high dollar race fuel for play riding and practice days. The 2016 stock is plenty fast for most.

What do you guys with experience think I need for suspension. I'm sure I'll need a shock spring for a 195 intermediate, what about shock revalve or leave it? How about the forks? I know it's just pressure changes but what about a revalve?

Not sure who I should sent it to, someone local in michigan is always.a plus too if it turns out good.

First thing to do is get a heavier Spring in the shock. Don't need to anything else with your suspension except set it up for you.
For just having fun and practice days, that's about all you need, seriously.
If you feel like spending money, radiator braces.
If you want to play with power, get a remap, or buy the software so you can play around with it.
If that hasn't satisfied you, get a new exhaust system (power gains in comparison to price aren't great).

Any reason it has to be a Honda? When you say must do, do you mean want to do?

I have a brand new Yoshimura Carbon/ Titanium system for that bike, if you're interested. The box hasn't even been opened yet. I'll sell it for 1/2 of retail pricing. I'm pretty sure it will work way better than the single FMF, but I have nothing to back it up, besides freinds who bought the Yosh systems when they wanted the best pipes.

Let me know, if you're interested, Shaun

Suspension, I'm biased but factory connection. Remove the judder spring from the clutch.an engine breather kit from Tokyo mods and a skid plate.

Take that piece of shit fork off and get something with a spring on it.

That damn front wheel won't track in choppy ruts better than my pw50 with oem (revalved) suspension..

I have this with that FMF single. I swear it's just as fast as my 13 crf450r. Bike absolutely rips. 80hrs. No problems and Completely reliable.

Takes 3k to make that old Honda to get Husky/KTM level. If you are not racing Limited 250 just go and get 350f. That will last way longer and have more power.

Put on a pipe, remove filter screen and map it with a GET ecu. Get your suspension done and you will be fine.

Exactly what are you going to use the bike for? If racing MX what class? I would break it in 1st then see what you think needs changing for you..

These are some great ideas, although Im not sure what the ECU mapping does to a stock ish motor. I know you could need some adjustments for a drastic camshaft or something, but shouldnt the ECM add more or less fuel where needed to some extent? I would think a pipe and stage 2 cam would be the limit, but I would have hoped the stock calibration could account for this.
What are you getting with an ECU then?
