Dr Taylor...new dirt bike fork.

[cowpoos]

New kxf250 fork...spring in one leg....damping in the other

KX250F now features a unique 47mm Showa fork that separates spring and damping functions between the right and left fork legs. According to Kawasaki, the new fork is lighter, adjusts more simply and effectively (including a spring preload adjustment on the right fork cap) and offers a significant 25% reduction in stiction.

So my question is....a number of years ago we had higspeed and low speed damping between forks [Whitepower cartridges]and now with spring and damping in different forks...obviously with no springs in a fork you will get less debris in the oil....but what about the axle twist/deflection...especially in dirt bikes...on the front end?

The proof will be in the pudding! Its also likely a lot cheaper to build..........

i think one of the most exciting parts of these forks is the outside preload adjuster, i think that will be of real benifit,

True...Bloody handy!!

Got to agree with that, various aftermarket MX forks have had that over the years and twin chamber forks shelved that feature rather smartly. But it also amazes me how many riders never touch the adjusters or when they do they often get it badly wrong. But for reading the manuals which are in fact very helpful!

Come on Mr Taylor , a real man dont need to read the damn manual. We just figure it out as we go.

If you do both then even better!

But seriously its amazing how many people are afraid to touch the adjusters.

Or how many can't keep both sides the same. Heard of yet another case tonight, mate bought a used bike with 1 rebound adjuster seized closed, the other in a useless position; the compression adjusters were dissimilar too.

On the asymmetrical forks; weren't Marzocchi forks in the past set up this way? Or was that just rebound damping in one leg and compression in the other?

Pretty sure lots of mountainbike forks have asymmetrical configurations. Err, I think mine is just like this, spring in one side & damping in the other. Which begs the question: are motorcycle fork designers getting ideas from the mtb world? I would expect mtb's to have much higher volume and a higher degree of innovation in production.

My forks go up and down. What more do I need?. Actually the WP fork and shock manuals that came with my KTM525 have made it so much easier to set up. I have a good compromise now for both road and off road situations as this is my Adv steed.

The forks on My old Katoom were like that (marzocchi) comp in 1 reb in the other
