Welcome! I can't answer your first question, but some sites I would look at are: https://www.firstplaceparts.com/
https://www.denniskirk.com/
https://www.upnorthsports.com/snowmobile/snowmobile-clothing/

I have the most experience with denniskirk and can't really think of anything bad to say about them. They sell a wide range of products, ship things lightning fast, and have a great return policy.

 

Yay I have used mine but the shield gets hammered with the salt from the road. In some cases it's same helmet with a different shield like some HJC units others not so much.
I ice race motorcycles with a unheated HJC.

 

I can't say for sled helmets making for good motorcycle helmets, but good motorcycle helmets really don't unless you get an electric shield or winter based goggles if using a dirt bike helmet. I occasionally still use my arai full face motocross helmet with goggles if temps are above freezing, otherwise its a dedicated snowmobile full face and electric shield.

 

as long as helmet meets the safety requirements, , a double pane shield will work well on a motorcycle, just as it does on a sled
I don't see any shield having more problems with salt than another, all will get damaged when things hit the shield with speed!
and due to speeds more on a street bike, over (SOME ) slower average trail speeds, the full face helmet will be a LOT warmer than a pure street bike helmet will be, as most sled helmets are more geared towards being used in colder temps(NOT ALL THOUGH)
I would still wear a Balaclava or some thing to keep my head warmer , never hurts IMO, but you need to have a helmet made for the added layer on your head!

I would still be on the use of a heated shield(but again speeds being maybe higher average numbers) maybe not needed as wind will help keep a double pane shield clean better, till you go real slow and then you can open it up

 

Before buying sport specific helmets, I used HJC full face helmets and swapped shields.

What you will find is that Dual lens heated shields are not DOT approved. And have a sticker reading that. For the reasons listed above.

That being said, I had 12v power on my adventure bike and that last ride to storage was assisted with heated grips and heated shield. As others have stated, most snow helmets are just motorcycle helmets with a heated shield and nose cone that can be changed.

 

Yeah for some reason the heated shields are not rated for street use, which seems funny because your chances of hitting something on a sled are much higher than on the street (branches and what not).

Cars, and all the surrounding landscape.

I can't say that riding on trail, needs more vision then riding on a street. Off trail, probably agree with you. But all in all, vision is important.

All in all, you got the issue with fogging, and keeping your head warm

 

I bought a Skidoo modular years ago when I rode my bike year round in GA. The road and wind noise levels were ridiculous. The worse part was breathing. With the windscreen that was on my bike (Hayabusa) it dumped the wind mid chest and created a venturi effect on the breath box exhaust ports. It actually took effort to inhale. I had to pull over that remove the box which made the wind noise that much worse but at least I could breathe. Granted this was about 15 years ago and things may have changed by now but this was my experience trying it.

 

The insulation (padding) and over all build is different.
I compared my old Shoei with my sled helmets and the intake/exhaust ports are different. Design is different.

And I would never wear the Shoei on a sled and my sled helmets on a bike.

Matter of fact I did ride once with my first HJC snowmobile helmet on a friends bike and I made it a short ride. As another said I had to fight to breath. Had to open the visor, swallowed a few bugs uck

Well, not with HJC. Their CL Max is identical to the CL Max SNOW only the snow has a heated shield and a chin curtain. Those are the only differences, the shell is identical, I know because I own both. Even the street model has the snaps located for the chin curtain. Shoei doesn't make a snow helmet that I am aware of?

 

I'm sure a sled helmet will work. Why are you riding a motorcycle in the winter?

One thing I'll say, I'm not impressed with the safety of most sled helmets. I think that's the last thing on the list for most average sledders. I wouldn't want to go down on the street with any modular helmet or any of the snow specific brands like 509 or whatever. If you value your head get a quality bucket for it. Odds of going down on a winter motorcycle ride are probably pretty good so I'd prepare for it accordingly.

For what it's worth I use my motocross helmets for sledding and with a klim Arctic balaclava and double pane lenses in goggles, it's a perfectly good winter setup for any temps.

 

Why are you riding a motorcycle in the winter?

Cause sometimes it doesn't snow. And I'm an addict!

 

IDK how some of you come up with some of the things you post. HJC is like any other helmet company. Not all of them are DOT and Snell rated in all the product line and in all sizes just like any other company. The CL-17 is the same helmet snow or street DOT/Snell rated with different options you can purchase.It's one of several they sell like that so like anything else always check to see if the one you want has the options and rating you need whatever the brand.
Friend of mine needed a Snell rated helmet with a good number of X's on it and we discovered that the same lid in a smaller size was rated but the larger ones were not,who would have thought that.

 

Not sure what your implying but i've had hjc helmets and never owned one that got the snell rating, even my old als-1 jt helmet which appears better constructed wasn't snell rated. It really bothered me with the bikes after seeing how it cracked like an egg from the episode i had. I ended up getting arai helmets after that. They have a snell rating boldly placed in them, and appear far better constructed.

 

Found a decent article on DOT vs Snell vs ECE helmet ratings:
https://www.bikebandit.com/blog/motorcycle-helmet-faqs-dot-snell-and-ece

 

Pretty much the same heard in the past. Really amounts to this...if you have a 10 dollar head, go with a cheap helmet.

 

There are multiple Snell standards depending on the application:

Also these are interesting charts:

Snell helmets aren't legal on the street and DOT helmets aren't legal at the track. It's a crazy world. I have never seen a helmet with both DOT and Snell stickers on it. My bike is too powerful to ride on cold tar. Below 40 degrees it will light up the tire or kick sideways unexpectedly. It's no fun to baby it and worry all the time so I patiently wait for spring. I have already been through the broken bones phase and don't care to go back.

 

Some snell rated helmets may not be rated for the street, many street helmets made for motorcycles have a snell rating and are perfectly legal on the road. All snell is a private foundation that does more stringent safety tests on helmets if a helmet manufacture wishes to certify it further. Like said above it depends on the application, you can get a dirt bike helmet or kids bicycle helmet with a snell rating, yet it may not meet the safety standards for street use.

 

Oh please, the OP asked a question that was simple and yes sometimes a helmet is the exact same on snow or street and HJC has more of them to offer than others.
So if you are short on funds you could get on to do two sports.
