Before any of the complainers/bitchers/that bike sucks/D-bags/dimwits/trolls etc check in with the latest round of ridiculous negativity they insist on bringing to this thread…
Wow, just did a tire change and got my first look at Starks new lightweight inner tube. These things are insane! So trick!

Did you get a patch kit for those with the bike?
I can only assume they require something quite specific to do a repair. The Schwalbe Aerothan and other ultra light weight 'plasticy' Bicycle / MTB tubes have their own, dedicated repair kits.
Do any other bikes come with patch kits?
I'd assume the factory dealer service recommendation for all OEMs would be tube replacement with an OEM style tube in a puncture, not patches. From Honda's CRF450r owner's manual:
Is that inner tube really "trick" ?
Or just cheap ?
If it doesn't tear or puncture any worse than a rubber tube, then it is.
At least It lasted longer than the tyre
I thought mousses were "trick" , but that tube must help with saving weight.
I would say for sure not "cheap" based on the cost of other tubes of this style versus their rubberized equivalent.
Try to save that much weight with Titanium and then you might see a good reason to have them
How much lighter are they than a standard tube?
They claim 4lb? but that sounds impossible
It is a question directed to Bryan. I'm interested in if they have provided repair solutions, or, if it's a 'throw away'.
I am in No Way Anti Varg, nor these type of tubes.
They ( and light tyres) are a very effective way of saving weight - and one of the most important, easily felt weight savings.
I've used such tubes on my Enduro and DH bicycles. I prefer them over tubeless set ups in my area. It's sidewall tear and 'burp' city in my incredibly rocky riding. Well, those or HD 21" or 23" MC tubes, but they are quite the stretch on 27.5" and 29"s .
But, the 'plasticy/' tubes do require very different repairs. Yes, in a perfect world, you replace a tube, instead of patching it. But, it's rare that I don't have patched tubes in either my MC or MTB. I'm not one for throwing things away when they can be Safely repaired.
To those asking if they are Trick - certainly they are. The ones I've used are incredibly light, and, more resistant to punctures than std tubes.
But, they Are pricey.
For Mog - 4lbs weight saving over a normal Butyl ( or 'whatever rubber') tube. Yes, easily. Even, perhaps, the thin OEM KTM type, I reckon. And cripes, have you weighed ( well, I'm sure you have) a Truly Heavy Duty Tube? With my MCs, it's either an Ultra Heavy Duty Tube, or a Bib Mousse to get through a days ride in my area. You do what you can / use what you have to, to get a full days ride in, with minimal drama.
I compared the Stark rear tube with a used IRC rear tube i had laying around. The results were surprising. 10x lighter.
Stark tube weighed 156grams (leaning against wall slightly reduced wright to 152)
The IRC tube i had weighed a wopping 1455 grams!
Thats a weight savings of 2.86 pounds just in the rear tube alone!!!!! And its rotating mass. Yuge
Everything else is listed their site with prices but could not find inner tubes?
Im not sure if they are available for sale yet of if they are even planning on selling them separately. But think about the instant 5 lbs of rotating mass you could drop off all your bikes. Incredible.
I can understand the asking about a patch kit since the tubes are not available to buy if you get a flat right now. So the only options would be patching or replacing with a different style tube. If they do not plan on making them available for purchase separately from buying a full bike, they should offer or recommend a way of repairing them. Or if Stark is not making the tubes themselves, maybe whoever makes them for Stark will start selling them.
It would surprise me if they do not make them available for purchase after more Vargs have shipped. A spare tube is one of the basic extras I used to keep in my trailer . Even if it will never pinch, you still could get a nail or some other puncture . I bet that people would buy these for their gas bikes too. That's a lot of rotating weight saved.
I wonder what putting a regular HD tube into a Varg would do. If an endo would be quicker to recover from with the extra spinning weight? It is a good amount more/less.
Day 3 video is up! First day at Perris Raceway with my Varg!
Did you notice the writing on the inner tube?
Pit Row
It looks like my next set of inner tubes will comes with a free cell phone and a spare bike.
or you could just buy the wheels...

They offer everything but the tube 🤷♂️
Roczen said the Varg was fast and handled like a 125
Thinking big picture ….. having 2 wheels that are each 5 lb lighter would affect lots of things like handling, suspension and horsepower. Those are HUGE advancements!
BTW, those tubes have to be quite strong having survived 3 ride days and a tire change
Exactly what I was thinking, I wonder if factory teams have already been using light tubes or similar things like this. Maybe Michael Lindsey (ML512) can shed some light on this. I've been lucky enough to pick up a Dunlop Factory/Spec Tire and the regular tire we buy, and there was a big weight difference IMO. One of the main reasons we switched to Pirellis is that they were a lot lighter in comparison to Dunlop and performed better in certain conditions.
This is one of the biggest improvements I've seen on a dirt bike in a long time and glad Stark is pushing the future.
Anyone know where you can get those tubes. I would like to loose 5 lbs of rotating mass.
I think the electrics can already recover from an endo better than a bike with a transmission because they can get the wheel spinning so much faster. The momentum you can store in the rear wheel is a function of speed and inertia, so you can trade one for another, but the unsprung mass has lots of other downsides.
Here's the mtb. version of the tubes.

The race teams use a very typical rubber tube, nothing special. Dunlop has their own tubes, I have some, they're pretty standard on weight. Pirelli is in the same boat.
It's amazing more companies don't use stuff that crosses over , eg the aer fork is basically a Mtb design , and the stark inner tube looks like a Mtb type innovation, honda etc don't seem to be able to do anything outside the box ,the only thing is the reverse head from Yamaha and that tooka long time to get the riders to be comfy
