Swap it! If nothing else it would be a fun experiment. You can enjoy your 250 two ways.
pump gas low octane is all you need.
i will admit to using pump gas 93 octane but my stock head 300 doesn't need it.
i've used 87 with no issues.
but i also don't think E10 is a problem. it's the E15 and above that's the issue.
Action shot from Sundays enduro. I'll post more if I find them.
Decent form on this. Head is over the bars. elbows could be out more. Legs gripping the bike good.
Solid rear rotor as opposed to a wave rotor? I though that was going backwards!
KC - You make the bike look small!!
My rotors were replaced. Strange brake caliper move gone. I fixed it...and cleaned my garage doing it. Long story...
It's a mini bike
I'm about to pull the trigger on either a 300 XC-W or a 250 XC-W tpi. My Brother has recently moved to Grand Junction/ Fruita, CO, so I've got a good excuse to be in dirt bike mecca a few weeks a year, but just wanted thoughts on one vs the other. I haven't owned a 2-stroke since my old KX-100 when I was growing up, but the NEEEED is strong at this point.
I've read all the reviews, watched everything on youtube, etc. And yes I realize this is the 300 Thread, but was hoping for a little real world input. Any would be much appreciated!
It feels so tall and lanky to me.
Especially after giving the kids a ride on the PW50... ride the kids on the 300 and it feels like we're up in a tower or something.
What kind of input are you looking for? You've already read all the reviews and seen all the vids by your own admission. You clearly already know the power advantages of the 300, and the user-friendliness advantages of the EFI. Are there any specific questions you have not already answered by those?
Or should we just do an "I'd do this, he'd do that" kinda debate?
Is your brother in on this plan??
I guess I'm kind of wondering thoughts on buying the (likely) last year of the carbureted bike or would you wait for the TPI version? Or conversely, would you potentially shy away from a first year TPI bike with potential "nuances" to be worked out over then next few years?
Also some of reviews talk about pretty short fuel range/mpg comparatively to the carb'd 300's, like potentially half the MPG average of a well-jetted 300 or 250. I'm not buying it to be a dual sport, but don't hate the idea of the ability to get 60 mpg running around the mountains all day if that's what's on the cards.
I understand that the power difference will be negligible for someone likely to not be riding the bike at its full capability....
Power difference will be very noticeable when not riding it full out because the low end torque on the 300 is where the biggest power advantage lies.
EFI will be more efficient, fueling only as necessary, and thus able afford better gas mileage. Nobody is getting 60 miles per gallon however (unless turned off for long downhill stretches half the time). The best I've gotten on my 300 is 36 miles per gallon. I don't know of anyone getting any better (w/carb) who has actually measured the precise fuel consumption at the pump nozzle. Theoretically, an EFI equipped 300 should be able to beat that. Theoretically, a 250 should be able to beat a 300.
Whether a person prefers carbs or EFI, or whether they would buy first out technology or wait for possible Kinks to be worked out, those are all personal decisions. There's the obviously well known pros and cons to these options, as well as superstitions. And there's always a level of "you roll your dice and take your chances".
Me, I'd pick the EFI equipped 300. If I needed an interim bike, I'd pic some old used inexpensive bike to tie me over.
I find that I can be in the wrong gear (1 gear too high) and the 300 will still pull me out of a spot. I don't really recall that being true with my old 250. I've always been worried about new things on a dirt bike. I worried about disc brakes wearing out too fast. About liquid cooling being too vulnerable. those problems never materialized. so FI should not be a problem based on my former fears. If you have been on 4 strokes for a long time (I was) I think you will like the 300 better. Easier to use power delivery. (I've pulled the grey wire and use the yellow PV spring)
I just feather the clutch a little when I'm in the wrong gear on the two fitty. That being said, I think a carbed 300 vs tpi 250 is all personal preference. You really can't go wrong either way.
Na, they work good in the gnar. No need for a guard and they last forever.

Interesting. I have one on my spare wheelset. I just figured it would heat up faster than a rotor with holes in it
The 300 when available here in the USA will really be second year of production. Most all current production is going to Europe. Dirt Bike Channel on Utube has the most comprehensive series of comparisons EFI vs Carb for the 250’s that I have found. You probably have seen them. Longtime readers of this forum and owners will admit that the carb versions need work to run acceptably, especially at different altitudes. If you don’t enjoy screwing around with Mikuni, Smartcab, Keihin, etc devices much you probably will really like the EFI bikes and the better economy, crisper throttle response, and end to premix hassles. Ten years of development work has gone into this. What we don’t know is what the upfront increased price will be for the 300 models. I would buy the EFI bike if I purchase another. For me the harder choice would be 250 vs 300.
I've been battling brake fade for the past couple rides..
So far I've changed fluid, put on new pads because the old ones were getting a little thin, and adjusted the brake pedal so it's lower and has more play.
I've got a reservoir extender, and banjo joint extender on there way to help resolve this issue. If that doesn't work I'm going with the solid rear rotor.
More mass -> longer to heat up and longer to cool down.
All bikes came with solid rotors until the improved (?) ones came out, and of course everybody then wanted the new designs. Aftermarket companies rejoiced!
