- Tubeless rim conversion using 3M Marine Sealant #5200 on Moto Guzzi V7 Racer III rims. $25 for the sealant and $6 for the valve stems. Super easy to do and now I can simply plug my tires if I get a flat - no more tubes to worry about.

Great video. One detail I would change is to use the 3M 4200, not the 5200. I work with this stuff daily on boats and the 5200 is an epoxy grade, permanent bonding adhesive that literally pulls layers of fiberglass off with it when you try to remove it, so I assume it would be absolutely insane if not impossible to remove from the wheel should you ever need to repair a spoke, or change your mind. The 4200 is still a 500psi tensile strength poly and could be removed if needed. It’s also much quicker to cure.
Even when fully cured the 5200 remains flexible - so a very sharp blade will cut it. cuting out a small section to remove and replace a spoke might be a pain in the a$$ but it is doable. My tubeless conversion is still going strong and 100% leak free. Thanks for the expert suggestion - it's worth considering. Continued safe riding to you.
Hai usato il 4200 sui tuoi cerchi?
Hi. Is still good your wheel without leak?
Make sure to clean well and to allow the sealant to actually cure. Had one were the certriffical force pulled sealant away from the rim.
I agree ! The sealant really needs to cure fully before a tire gets mounted. Continued safe riding to you.
NIce thanx. Just got a 2024 Honda Transalp 750 XL with tubed tires.
There are balancing weights for spokes (outside the rim) for those that do not know.
I LOVED my old 1994 Transalp! Wish I'd never sold it .... ah well the new one is on my list to test ride for sure ! Enjoy your new ride ! I am sure it is fabulous! Continued safe riding 2 U.
I did a similar thing 15 years ago on the rear of my Africa Twin, with a Sykaflex product, less liquid and mouldable, leaving a thickness of 5mm above the spokes, because these sometimes push inwards and can cause a loss of pressure.
Do you still have the bike ? I get asked a lot how long this sealant will last and I am guessing - but probably at least 10+ years ? Continued safe riding 2 U.
@@thebritonabike Yes I still have it, but the 30 year old rim has started to be corroded, small parts of aluminum are falling off, and it can no longer guarantee an airtight seal on the edges, the Sikaflex strip on the other hand is immortal, despite the many tires changed manually which stresses her quite a bit.
Side note, I have run Heidenau K60 Scout tires for a few years on 2 different bikes. Never had a puncture. IMO they are fantastic tires. Not super great in wet weather on tarmac but a great 50/50 Adv tire.
Thanks for sharing! I am loving these tires - once hot they are very sticky and confidence inspiring ! I tend to avoid riding in the rain so I don't have any experience on traction issues - but I am sure they will do just fine. Stay safe out there on 2 wheels !
@@thebritonabikethanks 🇬🇧
Nice video. Thx for sharing.
Thanks for watching! Stay safe out there on 2 wheels !
Hours and hours of work lol changed one yesterday on the trail in ten mins.
Hi @thebritonabike what are the implications if you do want to get to the screw head after having applied that adhesive ? can you take it off without damaging the grooves of the screw, maybe with a solution ? thank you very much for the video. had to search a bit to find something like this. cheers!
If the seal ever fails on the inside of the rim and you need to access or remove the stem valve you'd simply need to cut around the base of the valve with a blade to access it and then remove it. I added some sealant around the base of the valve for added leak protection. Continued safe riding to you.
@@thebritonabike thank you, to you too.

I just put my tires on the rims I let the seal cure for 6 days- front tire worked great, went right on sealed great, but I had trouble getting the rear to seat Tractionator GPS are very stiff walled. I ended up having to use the oxy-acetylene method, that worked very well. I will check to see if there is any air loss in them tomorrow then put them back on the klr
I have the pros at a bike shop mount my tires and rims - these days the tires are so stiff you need an industrial mounting machine to do it without damaging the wheel rims. Stay safe out there on 2 wheels!
Just get a ratchet strap and ratchet around the tyre as you put air in it, it will set the bead every single time easily and quickly, it's the best method honestly
@@danielkerr4100 Great idea .. I think I should do a video demonstrating that technique! NICE. I wish you continued safe riding !
Nice vid...
Thinking about doing this on a nee Tenere 700.
With reference to tires, thr K60 Scouts are top notch. I ran a set on a Vstrom 650 and now on a Vstrom 1000. Not as good on wet asphalt as Avon Trekriders but last MUCH longer.
Cheers
Thank you ! I appreciate the positive comments ! Glad you enjoyed the video - I wish you continued safe riding !
what did you with the hole for the valve stem before, during, and after this process. so a valve stem can be installed easily after?
I slightly enlarged the existing hole for the new stem valve so that the tubeless valve will fit. Cordless electric drill with a metal bit. After the new valve got pushed into place I did add a little bit of the sealant around the inside edges of the valve for an additional airtight seal. Tires are still holding air perfect with the tubeless modification.
If you live in Arizona or a hot climate note the heat rating is 190 Fahrenheit or 87 Celsius. 3M says " Long term exposure to temperatures greater than 80º C will decrease tensile strength over time."
That’s simply not true
@@KadeStringer2.0 Do you think I dreamt that up or took it directly off the 3M site? You could look that up yourself.
I agree if doing this on sumo, the rubber will get quite hot. I would not be that concerned for offroad or travel bike. I can't remember a time when I couldn't hold my hand on a tyre even in scorching hot sun.
Excessive heat will degrade pretty much anything especially rubber but so far so good and it gets pretty hot where I live 110 degrees in the summer months is normal. Tires are holding air and the sealant seems fine. Stay safe out there on 2 wheels!
Are you boiling hot person? 😅
Nice tires
Thanks 👍Glad you enjoyed it - Thanx for watching - stay safe out there on 2 wheels.
Is there any different between normal 5200 (black) & 5200 fast cure (white) in term of strenght/self leveling/viscosity?
To be honest I have no idea …. Probably …. the fast cure might have slightly less adhesive strength, like with JB Weld products , the quick set has a litter less psi hold strength. Best advice I can give you is check the 3M web site and manufacturer technical specifications. FYI my conversation with the 5200 black is still holding perfectly, no leaks or issues! Good luck, and continued safe riding to you. Thanx for watching.
@@thebritonabike thanks for the advice, definitely gonna choose 5200 normal cure because of the psi hold strenght.. Good luck
Great video and tubeless tires get less flats and are safer than the tube garbage.
Very true ! Thanx for watching and continued safe riding!
ciao, ho eseguito la tua stessa procedura, le valvola che ho montato sono con guarnizione in gomma sotto ma ho visto che tu le hai siliconate intorno, non dovrebbero essere libere un millimetro circa per far sì che funzionino correttamente? Grazie per la risposta e per il tuo video tutorial.

Can you share where did you buy the sealant so cheap? I was able to find only for 60 GBP only.
Here in the USA Amazon sells the 3M™ Marine Adhesive Sealant 5200 for $22 , looking back I bought my tube from a seller on Ebay for the same amount. I just did a google search and came up with lots of options to buy. Not sure why it's so expensive in the UK? Best of luck in your quest to buy ! Continued safe riding to you.
Great video! Do you have a link or exact description of the valve stems you used?
Thanx and glad you liked the video. The valve stems came from my local AUTOZONE parts store. Slime Hi Performance TR416 Tire Valve Stem. Here is the link : www.autozone.com/tire-repair-and-tire-wheel/tire-valve-stem/p/slime-hi-performance-tr416-tire-valve-stem/582043_0_0
do you have to buy a brand new valve i assume ? Does it have to be made specific for that brand and bike or generic ?
Any decent fill valves will do - I went with new heavy duty high quality Stainless Steel .. just because. But if you have old valves that are good - then you can totally reuse them. I just figured new would be better. Plus at less that $10 for a pair of new valves it ain't gonna break the bank. Continued safe riding 2 U.
@@thebritonabike one more thing, thanks for the reply anyway… how ling does the modification last without issue ?
Do you need to change your tyres for tubeless ones?
You can run ANY tires you like - providing they fit the rims! Continued safe riding to you.
Do you think flexseal would work spray on or brush on?
I have no experience with that product. I'd lean to using what is tried and tested and works. Stay safe out there on 2 wheels!
I read somewhere some using epoxy to seal the rims, probably works the same too
I am sure that any strong bond waterproof epoxy would do the job ... as it was my first time attempting this I just went with the 'strongest' marine grade I could find. Measure twice / cut once .. no desire to have to redo it ! Continued safe riding to you !
I don't know, but epoxy my not be flexible enough after it fully cures. hope it works out OK.
How has it held up over the last 7 months?
Still no need for tape?
NO problems at all ... tires are holding pressure perfectly ! I am very happy with the modification and I highly recommend it !
@@thebritonabike brilliant, thanks
...and what of potential wheel balance issues?
I had no balancing issues when my tires were remounted after doing the sealant. But that's why we have spoke weights IF there is a need to balance a tire on a rim. Continued safe riding to you.
i need to do this on my GS
I think you'll be happy with the result. It's pretty tried and tested. Stay safe out there on 2 wheels!
How long they will be last under this process?
I can only state that 3M says that this sealant is a PERMANENT repair in a marine environment even below the water line. In this application (if done properly) the sealant is never going to be exposed to salt water or extremely harsh conditions - just living in the inner spoke channel bonded to the metal. It will also remain slightly flexible so any flex in the wheel should pose no problem. I expect that it will last a life time - or at least the lifetime of the rims / motorcycle. Only time will tell. If it fails at some point I will report back. Continued safe riding to you.
@@thebritonabike Thanks so much, I got the mission now😁
@@thebritonabikeBro kindly share your experience will help others and can learn from it
@@janaharajanrajan4652 Thank you - I plan to keep making and sharing good motorcycle content ! Continued safe riding to you.
Any idea about how w long will this thing last?
No idea how long but I am hoping a long long time. I'd put money on the stuff keeping a good airtight seal for at least 10+ years probably longer .. but only time will tell. Continued safe riding to you.
What valve stems did you use?
I used these stems - but did add some sealant around the sides as well to further improve the seal. www.autozone.com/tire-repair-and-tire-wheel/tire-valve-stem/p/slime-hi-performance-tr416-tire-valve-stem/582043_0_0
I wonder if the sealant splits if you need to tighten a spoke?
Good question ... sadly I can't give you a definite answer. I highly doubt it due to permanent seal and flexibility of the sealant. BUT to be safe if it was me I'd grip the spoke with some vice grips before adjusting the threaded nut at the rim and then tighten that up .. without letting the spoke turn. In my 40 + years of riding on multiple spoked rims I've never had to adjust a spoke - but then again I might just have gotten lucky. Continued safe riding to you.
Do tubeless tyres need a different profile rim to engage with ?
Tubeless rims are usually cast wheels with a lip or ridge (below) to help locate and seal the tyre bead securely on the rim. This lip is also considered a safety feature which stops the tyre coming off the rim should the tyre deflate on the move. This lip also makes removing and mounting the tyre difficult by the roadside if you need to repair a tube. It varies from bike to bike and tyre to tyre, but usually, with tubeless you only need to remove a tyre to replace it when it is worn out (or destroyed), not to fix endless punctures. In my experience of over 40 motorcycles personally owned I have NEVER seen a rim without a safety lip - even if an inner tube is being used. Maybe really old pre 1970 vintage bikes that ran tubes don't have the safety lips on the rims but on all modern bikes the rims will have them. Continued safe riding to you.
most tubbed rims use tubless typers anwway just with a tube these days
@@thebritonabike Hi - only adding a comment because the T7 is a very popular model. The front does not have a safety lip. I converted the rear but had to keep a tube in the front - a pain.
@@davidmathers1141 I agree - don't put a tubeless tire on a rim without that safety beed or lip on the inner / outer edge. My rims had them - so I had no issues. Continued safe riding to you.
Hey friend, buy a tube 2 measurements below the diameter of your rim, previously cleaned, install the tube and then cut it lengthwise, the sides will be on the sides of the wheel. Install the tire, inflate it and once inflated, use a cutter to cut the sides of the tube. The result is excellent and more practical.
Interesting idea .... I've never seen it done so I can't comment on the effectiveness - I'd be concerned that the flex of the tire when riding will cause the inner liner to move and possibly leak ? Continued safe riding to you.
@@thebritonabikeThis method mentioned is widely used by many in Brazil.
Are there any UA-cam videos showing this "Brazil" inner tube method ?@@luziosalles324

i think tape was used so you can fit a tube for emergency fix in case of larger damage
Even after doing this conversion you can always go back to using a traditional inner tube. Continued safe riding to you.
What psi did you end up running?
Maybe the tape is to protect the sealant when mounting the tire. The bead needs to drop into this area and there’s usually a lot of force on it.
Hai carteggiato prima di usare il silicone ?
No I Just cleaned with wheel with paint thinner. ///// No, ho appena pulito con la ruota e con diluente per vernici.
@@thebritonabikeresiste ancora ? Io usero sikaflex521uv
how good this sealant holds up??
Probably longer than the life of the wheel .... ask me again in 10 years if the sealant is good .. except by then I probably won't own the bike. Suffice to say it is still good - with no leaks. I wish you continued safe riding!
But, when you adjust the spokes, doesn't that break the seal?????
It's possible - but realistically how often have you adjusted your spokes ? Spoke adjustment involves tightening the spoke nuts on the outside of the rim. The spoke head on the inside of the rim is locked in place and shouldn't turn or spin as long as it isn't damaged... thus the sealant on top of that inner spoke head remains in place. But like I said I suppose you could break the sealant if the spoke breaks or your rim is so badly out of round that serious adjustment is required .... if anything the sealant will hold your flat spoke heads in place even better . I wish you continued safe riding.
@@thebritonabike I always check the rim at every tire change. More often than not I need to adjust a few spokes to keep the rim true.
can I put tire sealant?
Yes if you want to add it - it won't affect the rim sealant. Personally I have had 100% success with rope seals vs liquid sealant which is not guaranteed to work - I wish you continued safe riding !
Hi mate are you still happy with it, any leak?
No leaks - still holding air perfectly ! Stay safe out there on 2 wheels!
@@thebritonabike Thanks mate.

Glad you liked the video - please continue to ride safely !
Ciao ! Ha funzionato la modifica?
Sì, ha funzionato perfettamente! Lo consiglio. Grazie per la visione e continua a guidare in sicurezza per te.
I run tubless on all my mountain bike rims. I put a latex sealant in each tire. Should you use sealant or not ans why on a motorcycle? Thanks
Me alegra que haya funcionado para ti. Gracias por el comentario. ¡Conduzca con seguridad en su motocicleta!
@@Ridewithcoko I only have experience with the 3M sealant - and it is working perfectly still. No leaks. For motorcycle rim sealant I would continue to use this sealant only - continued safe riding to you.
Way over-complicating it. Just get a tire tube one size smaller than the rim, cut the tire tube down the center, put it on the rim, put the tire on the rim, pull the excess tube out between the tire and the rim all the way around, air up the tire, trim the excess tube all around the rim on both sides. The innertube seals off the nipples inside the tire and acts as a gasket between the tire bead and the rim bead. Simple, effective, no tools required besides a razor knife. Hope this helps.
Agreed - your way is much cheaper, simpler and quicker ... but that's not the way I chose to do it ! Thanx for the comment and I wish you continued safe riding !
@@thebritonabike I will say your way is much more durable, you won't have to change the cut tube everytime you change tires, and I believe there is a fast-dry version of the 3M Marine Sealant you used that dries in 24 hours.
Measure twice, cut once and do it right the first time to avoid costly repairs, do overs or unnecessary fixes ... the 24hr dry time 3M sealant is available and has a little less overall strength when finally cured but I am sure it would be fine ... because my bike was getting rebuilt I had plenty of time to do this type of mod + cure time etc as I wasn't in a huge hurry to ride it .... nearly a year later my tire pressure is still perfect and no leaks! Continued safe riding to you. @@BillySBC
If your spokes never loosen you aint riding hard enough
When you tighten loose spokes the threaded portion of the spoke extends outwards or away from where they attach to the inner rim. By making the rim tubeless you can still tighten loose spokes the usual way. ONLY if a bent or broken spoke needs replacement would you have to push the damaged one through the sealant and replace. Then all you'd need to do is add a blob of sealant over the repair area. Continued safe riding to you !
If this was such a good idea bike manufacturers would do it. BMW spent fortunes on spoke wheels but they didn't do this because it's dangerous.
It's Absolutely NOT dangerous. It's simply an effective MOD that allows U 2 plug a tire rather than remove it and fix a leak in an inner tube. It's also removable if you need to repair or replace a spoke. Its' NO different to riding on NON spoked wheels. - Thanx for watching - stay safe out there on 2 wheels.
You are using a marine sealant to seal spokes. Says it all really. I'm sure this method is endorsed by the bike industry.
You say this method is absolutely safe, if so I would love to see what you base this on. It's Russian roulette, absolutely safe until .......!
The 3M sealant is PERMANENT, flexible, bonds to everything and the absolute best thing to use for this application. Anyways - No worries - let's just agree to disagree. These kind of mods are very common, and there are hundreds of other UA-cam videos where owners have done exactly the same thing to there wheels successfully - hopefully with no ill effect. If you are careful, thorough and accept the risk - as with most motorcycle riding nothing is 100% safe. All I have is my own experience of 43 years of motorcycle riding, owning almost 50 different motorcycles and riding 500k accident free miles. I've never been a fan of inner tubes, and repairing a motorcycle inner tube out on the road is a HUGE pain in the AS# ...... anyways thanx for watching ! Stay safe out there on 2 wheels. All the best.@@stephenparker6288
well stated@@thebritonabike
I’m doing it on my next tire change.
The tape it’s used to prevent delaminating due to centrifugal forces, ok you want to diy but at least don’t make a video about it.. this is very dangerous stuff, wheel and brakes are two things you don’t have to improvise AT ALL!!
Whist I appreciate all comments, providing they are constructive and I respect individual opinions - you are completely wrong. The inner tape on spoked rims is simply there to prevent the inner tub from rubbing on the heads of the spoke heads and 'possibly' causing a puncture to the tube due friction or wear. There is NOTHING inherently dangerous by sealing the inner rim with the correct sealant to prevent air leaks. There are literally hundreds if not thousands of other UA-cam videos on exactly the same procedure. But if you think it's dangerous then don't do it. Caveat emptor. I wish you continued safe riding.
I've had to replace damaged spokes several times. This isnt a good idea!
Better with properly deigned rims with spokes on outer part of rim.
I agree though tubes are yesterday's solution. All bikes should be tubeless by law now!
