No linkage eh?

Recommended Posts

I noticed that Ktms have no linkage. For those of you that have rode on a yammie or a Honda with linkage....can you tell any difference? Does the bike handle differently? Does having no linkage give you more travel on the rear shock?

having no linkage makes your bike lighter and simpler to maintain. it probably is a slightly different feel but i haven't ridden many japanese bikes with really dialed suspension, so i'm not sure i could tell. ktm achieves the same sort of progressive action with the valving and stuff. not sure what the travel is on on japanese bikes, but ktm's are over 13" in back, tho they do require a little more sag than linkage bikes, so it probably ends up being about the same.

by looking at the results of enduros and mx races, it seems clear that a non-linkage shock can perform just as well.

The KTMs don't have as much of a rising leverage ratio curve as the linkage bikes. The the leverage ratio curve is something like 11% on the `05 bikes, whereas I think it may be 18% - 20% on a CRF.

KTM used to ship with progressive rate springs to compensate, but they've caved in to the wishes of MX magazine writers who have said that the KTMs should be switched to straight rate springs. I disagree with them.

KTM doesn't actually compensate for the lack of linkage (a spring rate thing) through valving (a damping thing), but the valving does have a fairly progressive damping curve thought the use of two valving stacks that helps prevent bottoming out on high speed hits.

Hi,

I ride both---KTM (no linkage!) and a Yamaha (linkage!)!

Compared to the Yamaha the KTM suspension hooks up a little better on acceleration bumps but is more nervous on braking bumps.

You have to set up the sag different on the KTM, but otherwise there is no big difference!

....just to mention, I prefer the straight spring over the progressive spring on the KTM, because it gives me a much better feedback from the suspension!!

      Looking for something a little lighter and faster to supplement my xr650l and I think this bike might fit the bill. I'm hoping there are some owners here who can give me some insight into the typical experience with this bike. The question I'm most concerned about is how many hours these engines last before needing a rebuild with normal trail riding? Also, how do they handle in technical terrain? How about on the road? 
       
      The machine I'm looking at has about 75 hours and 1,500 miles on it, all stock other than a lectron carb, and comes with some dualsport lighting not installed. The current owner's asking price seems pretty high at $4500, but he seems to be a communicative, eager seller, which is practically unheard of in Upstate NY where the vast majority of dirtbikes on Craigslist are owned (or "owned") by rednecks trying to flip them. I'm willing to pay a little more than market value for this reason.
       
      Thanks for any input!

      Hi all,
      I got a set of the Axis passenger pegs to fit my 14' 500 exc. The bike does have the alloy sub-frame, but I'm curious if anyone has used this set up with success without destroying the sub-frame or their wife/gf? 
       
      Short trips like errands and rides out to the coast for hiking. 10-15 miles on the longer rides, and likely 0 miles on the highway, as she is not super stoked about riding. But our job kinda doesn't allow multiple vehicles. Yachties. Also shopping a sumo set up at the moment too. 
       
      Thanks folks!!

      Recently,I took a trip out to Colorado for some R&R on a family vacation. I brought my riding gear and had planned on renting a bike, but I was too late and at least what I looked at, there was no availability for my timeline. Bummer, since I'd not ridden the rockies in over 4 years, something pretty special when you live in flatlanderville (Florida)! 
      But, behind the scenes, a couple of TT'ers were at work! Through TT, we recently hired a fine, young gentleman to head up our advertising sales team,( @Freemotion ) and he pulled some strings with a local who had a well equipped  KTM 450XC-W that is his back-up machine. His new love is a 2019 KTM 300 TPI and it was gorgeous!
      So, a HUGE thanks to @Freemotion for greasing the skids in getting me a skoot and to @G 9.5 for generously lending out his bike to basically a stranger. The weather was great, so was the company, and the riding was epic as far as I'm concerned. I'm still a bit humbled by the generosity, so I wanted to share a story that I bet isn't as uncommon among the riding community as one might imagine.
      Dirt bike people rock! 🤘

      Hello TT peeps. I currently have an 11' Ktm 450 exc which i am converting to sumo. Still on the fence about getting cush drive rims or standard rims. Not too much info on what cush drive does for wheelies. I know its smoother on the tranny and chain but will it make much of a difference with slower wheelies/stunting? I had a DRZ with standard rims and slower wheelies were very choppy and almost impossible to control smoothly. Any advice/tips/help will be much appreciated. 
      Also.... will 5" rims be pushing it for chain rub? Should i just stick with 4.25"?

      Hi, I was wandering if anybody has recently bought or sold a 2014 or 2015 500 exc?  I'm trying to get an idea as to what they worth presently.  Thanks for any help.
