New KXFs

[Crasherfromwayback]

the factory ones i have seen pics off had bladders that hold the air/nitrogen

So do 35 year old Fox Air Shox.

The air we breathe is 78% Nitrogen anyway, it would be interesting to see how hot they get. They have a lot more cooling then mountain bike forks because they are a lot larger and the bikes are going much quicker.

.

Whilst I know forks hold more oil to help with cooling than a shock, DK's rear shock used to get that hot that if you spat on the shock res after a moto it'd sizzle. I'm not by any means saying the forks won't be really good...but I'll be interested to see. Air caps were removed from forks years ago. Yes I know they had springs in 'em too.

I spent a fair bit of time messing with air / spring forks a long while ago. They offer a lot of advantages but their biggest disadvantage is the fact that they suffered from much more drag on the seals, which has to deal with that pressure through hours of abuse without losing gas.

Still, maybe seal technology is more advanced, now than I give it credit for...

There a alot of differnces between a rear shock at the front forks

No.1 It has to do a lot more work and is under a lot more pressure due to the leverage of the swing arm then the front forks so more heat is generated.

No.2 The super hot exhaust runs 10mm below it

No.3 Minimal air flow compared to forks

No.4 Less surface area for heat dispertion

Not about to argue with you there! My point being though...even on the Fox Shox of old (which have huge finning and don't work nearly as hard as a single shock), pressue build up was a rather large problem. So whilst I know forks won't be getting anywhere near as hot...I still think it may be an issue. Be glad if it's not, as the idea seems a good one!
