    kdx 250, kx 250 difference's ??

    what is the difference's between the kdx 250 and the kx 250 models other than a lighting coil?? will a light coil from a kdx fit a kx?? are the motors and suspension interchangeable? same power? anyone ride both? and which did you prefer and what type riding?? what would be best for open desert? riding at night would be a plus. TIA!

    sorry for the double post,but new to site and didnt see the kdx only section till after i posted it in the cr,rm,kx section

    The KDX 250 motor is basically an 88 KX motor with a heavier flywheel weight and milder porting. It has more low end power than the KX. There some parts that are interchangable, and with a little work it can be turned into a great bike.

    i was wondering the same-thing (parts interchangeability)
    especaily the rear shock, and swing-arm. does the kx have stronger rear shock/ spring? & will it fit kdx?

    It's a completely different, much cheaper rear shock. The KDX also has a shorter swingarm than the KX, part of the reason it's so wheelie happy. The swingarms don't interchange without some work.

    Hey what about the biggest difference... The Trannys are totally different!!! The KDX 250 is a wide ratio...

    I bought a KX planning to ride only woods. I assumed it would be a more durable bike than a KDX (plus I got a killer deal on one). According to Spanky 250 I guess I could be right. But recently I've been wondering about the gearing. Speedy is saying what I think I wish I had.

    I'm getting ready to have it rebuilt by Eric. Due to flow through crank seals, I had zero low end, and steep trails were impossible. Eric's gonna put more low end in it, but should I think about changing the sprockets to lower the gearing? Or, would my top gear be too low (due to the close ratio)?

    Plus, will a lighting coil from a KDX fit my KX if I want to shine at night?

    BTW Spank, thanks for all your help last fall!!!

    Almost forgot!

    Is the air box any different i.e. letting you go through deaper water? I'm about two wheels shy of being just like everyone else I ride with.

    The KDX 250 has alot of bottom and mid range, no top end whatsoever. It has a heavy flywheel too. Which is the main reason for that.
