Weight difference?
« on: February 25, 2012, 04:00:16 AM »
Does anyone happen to know what the weight difference is between a kx250 motor and a kx250f motor is? My suspension guy was hoping i could find out as it apparently has a bit to do with how were going to set it up

Looks like about 7 pounds, don't think that's enough to worry about on suspension mods.

Have you ever feel how much a 2t 250 crank weight, compared to a 4t 250?
And than the lighter clutch. Still it's special.

R&D $$$$  :-D
The money has been in 4T.
If the manufactures were to spend a little of that for 2T development it would be a different world...
I think the average rider would be shocked at how little 2T's have actually changed in the last 15-20 years.

CR250f X with electric start is 59 lbs, CR250f R is 53 lbs.  CR250R engine is 51 lbs.  I doubt the KX 250f is 7 lbs lighter than the 2T.

Well, I weighed the 04 KX 250F motor I was getting ready to put in a bike.  You don't have to believe me I guess, but that is what the scale said.  It was complete too, except for the items noted.

what it really comes down to is the 250f performs like a 125 2t, and the weight difference there

Sorry, I wasn't trying to diminish your contribution just pointing out a discrepancy.  Perhaps the kick starter, carb, and oil level account for the approximate difference.  A quart of oil itself is almost 2 lbs.

Yes this included oil ,kicker and plug no carb,it might be a tad lighter than the twoey but it does not last as long.Over a 3 year period of racing its cost a lot more on parts the 250f has over the kx250 06.Everthing being equal.I m talking about engine components ,the 06 twoey has been virtually bulletproof.
