Only interested in the 2011 KX250f because I got a deal on it, if I want it new.
I like the features (forks, adjustments, FI) Have you plugged in a laptop or computer and made adjustments using the plug behind the front number plate? Noticeable differences between settings? How do you think the electronics will hold up over time?
All of the front line MX bikes have nearly identical features. All of them are using EFI, with the exception of the yamaha
the EFI tuning maps are not that distinguishable, a really good rider will notice the difference between maps, but most won't they'll tell you how much a difference it makes but if you made blind changes, most riders would not know the difference.
the custom tune feature will just have most that choose to use it making the bike worse than it was and more difficult to ride.
All of the FI bikes have this capability with different add on or OEM tools
The data acquisition feature of the ECU is cool however, and if you understand the information it returns, its a brilliant tool.
the new fork is a good step forward, its about time external preload was available on an MX bike
(just don't tell anyone on this site that there is only a spring in one fork, they'll tell you that you're crazy and that the bike will not function properly)
Can you rank the motor out of all the bikes. I hear its strong and smooth from low-mid-high because of the FI. True?
it has one of the best 250 motors available, but, this also makes it more of a handful to ride, honestly, to tell the difference between any of these bikes, you really have to be a professional knit picker and REALLY search for flaws.
Would use on track. Have land (100 acres) and currently in the works of designing my own track on about 2.5 acres with expansion to add another acre which I have set aside. Mid june / start of July should be done. The rest of the area and surrounding area there are trails which I could ride as a secondary purpose as well.
I'm not telling you any more unless I get an invite to ride(who's designing the track? what level MX experience do they have/do you have?)
