I'm going to find out tomorrow.

 

It should! when i did the 450R swinger conversion I used a G-Force axle with the stock nut and from what I gather they all use the same nut, 450R, 250R, 400ex

 

Mine worked

 

Got a 400EX G Force axle in my daughter 250R & using the stock Honda axle nut.
The change over to the 400 axle, you'll notice the sprocket is out of line by about 3/16 of an inch to the carrier. Its not enough to cause any major problems other than the inside of the chain will rub the plastic chain guide on the swingarm. I just took the guide off & clearanced the back side of the guide so it would be more to the inside & the chain not touching now.
Other than that, you'll need 400EX, 300EX or 250X hear hubs, because the splines are different from a 250R axle.
For 180.00 bucks to the door, that new TROME AXLE IS A LOOKING GUDE on dat ol 250R.

I would save my money and buy something a little better in quality IMHO. G-Force axles will not last under hard riding. Watch eBay, I picked up a RPM Dominator for under 300$ that is straight as an arrow and I would say a 9/10. That Lonestar axle nut will cost almost as much as the G-Force axle But, if you do go that route, it will work. I have a Lonestar anti fade on my dominator.

 

I don't know...the G-Force do pretty good. I've been using them for years. Ran one on every sport quad I've owned and never had an issue. Now does that meant they don't break or bend...no but heck for the price you really can't go wrong.

 

Its life time replacement if it bends just like the others on the market.
