Best race gas for stock 250F?

None

None if it's stock wasted cash just keep fresh pump gas. If stored in a plastic can after about a month it will start to drop off on octane rating. 

If you want better than regular pump gas say ethanol free. Usually still sold at farm Co op's. Usually runs about a $1 more per gallon. 

If you where to run any kind of race gas go with the 100/101 octane stuff sold at the pump. Usually runs around $10 a gal here. I run this in my 2 strokes to keep them from pinging. 

It does not add power 

I agree with what these guys are saying from my own searching. Run ethanol free 93.

I noticed great throttle response and more bottom end on my '21 KX250 by switching to VP T4 (all I use now) which is pump replacement fuel. Great stuff, I can afford it...

Correct answer 

You can, you just have to look for it. There are specialty stations that sell this stuff.

Something with oxygen if you want more power out of a stock engine. That’s the only horsepower in a can 

You must be real fast if you need more than a stock 250F.

Difference in laptimes?? Bone stock bike?

From what I read, here and other places, most suggest saving the difference in gas from T4 over pump for a stock bike. The consensus was there was little if no difference for the average rider. Last year when I looked at T4 it was $113 for 5 gallons at my local VP station. Not saying I can't swing that for gas, but why would I for the minimal gains most claimed you will see on a stock bike compared to pump gas.

These comments are always funny, I get them a lot. “You don’t need race gas or a modded engine”

go race a desert race against 450s and try to pull taller gearing with a stock 250

VP Racing has some fuel called C12 that will get your bike smelling right.  

I don't have lap times to go by, only "feel". I'm a weekend warrior. You think if a slow, older C class dude would notice the difference, everyone would. T4 is 100 octane, non-ethenol, and "oxygenated". So not quite an exact pump replacement as we don't have any non-ethenol fuel above 90 octane around me. 

In my opinion, and from the majority of peope I've talked to...the dudes saying it won't make a difference and swear by 93 pump gas have never tried a VP fuel.  I'm not doubting you haven't, but that's the general consensus. Even the other day at the track some dude was telling me pump gas is all I need, yet he had never tried a VP fuel ever "waste of money!". So IDK...just my opinion and what I've seen around here in northern Indiana. Most of the guys using any sort of VP fuel don't go back to pump...again just my small view of the moto community up here. 

VP T4 would be a safe bet. Renegade has a T4 equivalent and is cheaper. I wish I had a Renegade dealer near me, but I'm here purchasing VP in IL. 

They will.ship, if ya get a few friends.  Split the costs. Also. Ets  dragon ti lube will also.

I run vp110, there is a station in my town that sells it for $10 a gallon, I run it in my mini mod pitbikes and 250f. You definitely don't need it but I can also leave gas in pitbike carbs no problem and it feels nice to run good gas. If you wanna run some I would say vp110, T4, and I thick C12 are all good options. 

That's kind of his thing, some sad dude that just has to jab pointlessly.

If money is no issue, Pro 6 will produce the most power. But we're talking $40+ a gallon. Otherwise, T4 is likely your best bet for a stock, non mapped bike. 

You don't even ride dirt bikes so step off your pedestal. 

Even better... Just delete your account. 

You guys are having a real circle jerk, huh?

Never said your not fast Bro, just asking. I got nothing to prove and my riding speaks for me.

I think your posting speakes for you and it says "Im a dick" 

A BIG dick calling a little dick a dick, isn't that special.

Klotz has one similar T4. Free shipping on orders over $150.  Took 2 days for 2 pails to get to my house.  Cant say it will help in a stock 250, I use it in a modded 450 quad.

That is a bit higher octane than the T4. Looks to be a great option for 250F's with HC pistons.

VP T4. I find my 250 revs a bit freer and builds RPM slightly faster. Nothing huge not noticeable. I think the extra cost is not just power, but reliability, you’re basically ensuring you get clean fuel. I always go to a Sunoco that is frequented by wealthy folks and get 93, as I know they refill it regularly. I grab T4 as the budget allows. 

I run Renegade HR93 or HRP97 in my mildly modded 250F. I feel like it's a good middle ground between running race gas (which I think would be a waste) or running pump or ethanol-free pump - plus octane booster. The bike runs good, no gunk build up and the fuel lasts a while. 

Shut the fuck down   

Go show him what's up, tough guy
