Tubliss system
« on: August 02, 2014, 08:29:27 pm »
Tubliss tire system.

This is 1 of the best mods I've made. It's reliable ( I have given the bike **** over some shocking terrain) for over a year. I've had zero problems. The bike handles IMHO, noticeably better. Corners, trax, etc.

For an explanation of why, see here.

I've been considering this set up, but Tubliss says "for offroad use only".  Have you used yours on road?  At speed? 

Thanks!

Yes I have, about as fast as the bike will go, but I don't use it for long slab rides. I only use the bike as a big enduro machine - 95%dirt - not dressed up for adv riding as many ppl do. I only ever run full knobbies on it not dual sport rubber.

To date I've gone thru a few rear tires since I started using the tubliss...no flats, problems at all. I'd swear I can notice the weight difference in the way the bike handles. As far as I know, none of the alternatives to tubes are for road use? Could be wrong so let me know if I am!

I was told by a KTM dealer that the Tubliss might not work with the stock rear wheel because of its width.  Tubeless list their 18" unit for rims which are 1.85" ~ 2.15".  21" unit is for rims 1.65".  KTM shows stock rims to be 18" x2.50" and 21" x 1.85".  Are you running stock rims?  I'm looking to try these with Heidenau K60 Scout 50/50 tires or Mitas MT 07 Dakar 50/50 tires.  If you can beat them up off roading and on the street, they should hold up for a long adv ride or commuting on the street.  Also what tire pressure are you running when on the street?

Thanks

I got a reply from Tubliss yesterday.  They said their current offerings won't work for the stock wheels on the 690 enduro.  But they are working on systems for the bigger/wider rims.  They expect to have them available sometime next year.

 I got a flat last year when I aired down for a trail ride & spun the stem off after getting stuck in the mud. So thats what has me looking into a bead lock. I've been looking at Motion Pro lit Loc's or the Tubliss system.
Nut up or shut up!

As hard as a tire change is stock with trail side tools I'd be inclined to go tubliss.  I put a rim lock on my KLR.  It made tire changes more difficult but doable.

In my opinion the 690 would be no fun in the wild with a rim lock.  I suppose if you were just pulling a tube patch and replace you might be ok.

Just a thought.

The Motion Pro Lit locks are too narrow for our fatty rims!  :-(  I ended up with their regular rimlocks and about 14lbs of wheels weights :-)    ok, maybe not that much, but seemed close!
And for those wheel weights, I cannot praise these enough http://r.ebay.com/CXNk5x    Pricey, but worth it.  Reusable!

Funny they say that. I use stock rims and flog the bike something awful. Tubliss have held up just fine. I'll change the front tire very soon to check for wear and tear in it but I used to crack rims all the time, and after 3 flats in 1 week I decided to try tubliss.
I know of a few guys running on the stock rear rim who also use the system with no hassles.

Wow.  You either like to race around construction sites or you really race your 690 like a borrowed horse. :o  What kind of flats were you getting?  Pinch flats, blowouts, or punctures?

Pinch. Lots of rocks around here. I also **** 2 rims in 1 week. It was after that I stopped running my tires at 14 psi. They now sit just shy of 20 psi. No flats or dinged rims anymore. I also think the bike rides far better because the tires don't roll sideways on the rims which can happen with the bigger bikes.

And yeah, I do like to give it some off road  ;D

Guymcfly, so just so I'm clear, you're running 20psi with the Tubliss system as well? When my tires wear out, I'm going to switch to Tubliss and have read people running from 3-10psi, but not as high as 20psi with the system. Seems to make sense, just checking. Thanks.

Yes, the tubliss system needs to be kept at 100-110psi to keep the tire seated in the bead. The tire itself (you use a 2nd valve for this) can be run way down, at 3 psi if you want.
Because of the many large and small rocks I get to deal with, I keep my tires inflated to around 20 psi.

I've also mentioned using the bigger bikes (anything over 125kg, the weight of a fully loaded exc with long range gas tank), and I've always noticed that tires start to roll sideways on the rims during fast cornering, if the tire pressure is run to low.
It was something I noticed a lot on the 690 when I got it. Basically, theis stops the front tire biting properly and makes for a skating effect which a lot of people feel is the bike pushing into a corner. It's really not that; although to much rear sag does cause pushing...it's more to do with a lot of the tread of the tire failing to be the contact patch with the ground as its pushed well off to the wrong side of the rim. You then get a lot more sidewall making contact with the ground than you should have, so your very effectively running a semi slick tire.
I was a little reticent about voicing this until I read the 2010 690r review by Chilly White. He mentioned exactly the same thing, and the vast change in handling when he inflated the tires more than usual, so I feel a lot better about saying it.
Btw, his review is well worth reading.
