Nitro mousse

Slavens shows a Platinum in stock 

It's showing in stock at RMATV for NMS18-325. I've been bouncing around different companies: Nitro, Michelin, Wolf, going to try out Dunlop early race season.

Good excuse to switch to the far superior Michelin. 

I can have one drop-shipped to you today. Send me your e-mail address and I can send you a cart to purchase.

I tried nitro mouses for the first time ever on my last new tire change front and rear. 

Granted, I do not ride motocross anymore.But do a lot of hardcore off road out here in arizona, where there's a lot of rocks and you have to run about fifteen p s.I in the front which kind of sucks with a heavy duty tube. 

I was pleasantly surprised early on with them,how you could just plow through stuff and not worry about getting a flat or bouncing off rocks with high PSI.

But after about 14 months off the bike when I went for rides this season, I noticed the front felt like I was riding with a flat tire.I believe it also caused a crash, which totally caught me by surprise.

I took it to my local AEO shop to have them put on new tires as I do not have the proper equipment to change mouess's. 

They told me the front one was gone, and the rear mousse needs to be changed at the next new tire. Thought about going with the balls, but they did not have them in stock.So I had them put in a heavy duty tube in the front.

The rear still has the moose in it and pushing down on the tire with my hands. It feels pretty dang, soft and i'm kinda concerned but the tech at the shop thinks it will be okay.

So after all this as there were the pain in the butt to change them.I'm probably gonna stick with heavy duty tubes.Much to my chagrin..... 😬

So i'm not really sure what caused the moose's to get soft so fast.It gets real hot out here in arizona and the garage especially. That and the inactivity off the bike might have done something to the lube. I'm not sure as I had a friend install them and he put two tubes of lube in each moose, when he installed them.

Has anyone else experienced this?

They will dry out in general, if you let them sit for an extended time especially in hotter areas. Some brands offer stiffer mousses like the Nitro platinum or the Mitas rally versions. I lube them when I rotate tires needed for various terrains. I also have a MTB style setup, where I run two rim locks in the rear and then valve stem. I unplug the core and use a syringe setup and inject some lube into the valve and spin the tire a few times. I do that before each race.

I've found the different brands to be a crapshoot in quality and especially the art of matching the mousse to the tire carcass. I'm not a pro so I don't have the money and time to try various offerings to match preferred tires. I keep coming back to the nitro setups for best value for the money. I'm about to try the dunlops on AT82 for general/unknown and switch to MX3S/MX14 setup for sand,loam,or mud.
 

save the headache and just buy Michelin. Nitro mooses suck. Half the guys who claim they run them are not bty, just stickers

The Michelin is literally half the weight of the Nitro too! 

Thanks for the info. 👍My friend who installed them actually did do the rim lock and valve stem trick, but I had a lot of stuff going on in the last year in my life (losing my wife to cancer then my dog of 12 years) and I completely forgot about filling them with new lube.

It just seems with the massive expense and hassle of changing them they might not be worth it to me.... 

I've run the Nitro, Michelin, and Techno. 

Nitro is great the first ride, then they shrink. Before a tire is even worn out the bead is coming undone from shrinkage. And they are heavy.

Technomousse I used the Rally versions. They still break down even though they claim they won't. You HAVE to keep your bike on a stand as they do shrink when cold and will flat spot. Kinda suck for racing because they need to get heated up to feel right (expand). I liked them better than the Nitromousse though. Should note they are easiest to change due to being smaller when cold.

Michelin is the best. If I keep them lubed, can use at least one mousse for 2 tires before wedging them back up. If I start with the huge mousse in a Desert Race 140 width rear (rally tire) I can get one or two uses in DR rears, then move to a conventional 110/120 width rear for 1 or 2 more. Lightest mousses I've used so far.

Double rim locks in the rears. After a mud or race with lots of water crossings, pull apart and relube. I just pop part of the mousse out, squirt a half a tube of lube in, then squish the whole thing back on the rim.

I will be experimenting with the new Nitromousse 5150/Tubliss combo in my hard enduro rear wheel. Will figure out how that works this coming summer. Already mounted up with an IRC VE33s gummy.

I also plan to pony up the bar and TireBall a front wheel. Just a big initial spend, even compared to the mousses.

As others have said, nitromousse was great initially, but shrunk/felt soft very quickly. It lasted exactly one set of mx34s

Loved the mousse, and will not be switching back to rubes, but the next set will not be nitro. 

Dunlops last a while but they are a lot heavier than the Michelin. The Dunlop 18” rear is barely big enough new to seat the bead on a 110/100-18 mx34. I think they need to make that one a hair bigger. The front fits the mx34 and 33 pretty well new and after using it for a year. When Dunlop is running a rebate it usually applies to mousses as well as tires. 

Mousse balls have a new version that doesn’t require lube. That would be nice. 

They are significantly lighter and retain their density for far longer than a Nitro. I race all season on one set in MN/WI.

Agreed , have been running Michelin bibs for 4-5 years now with zero issue and longevity is awesome 

You are asking about the Soft version Nitro Mousse. They are considerably softer than Michelin, and used for technical enduro riding. If that's your type of riding, use the Soft Nitro.

Nitromousse is the worst. Michelin and dunlop are top tier.
