Title: Rear sprocket Gaurd CMX/CDT
Post by: Tossa on March 15, 2013, 08:31:18 pm
Been reading the new MOMS tell me if I'm wrong, it states:

12.8.8.6  Other than CMX/CDT a chain guard made of a suitable material must be fitted in a way to prevent trapping  between the lower drive chain run and the final drive sprocket at the rear wheel

that means to me no chain guard required!!!

It also doesn't list a bar pad for that era as being compulsary

That's terrific, I've been holding off welding a brackets on my nice nickel plated swing arms until I could get the nerve to do it, now I don't have to. That's great news.

So Mark, are the moms the gospel or can your local club make you fit one and a bar pad to ride club events. Who overrules who basically?

Cheers

Don't take my word as gospel but I think MoMs rules over all Ted.

it's also the same with footrests

12.8.5 Footrests other than CMX/DT Footrests must be:

a) well rounded and designed so as to ensure that no dangerous edges are created due to wear
b) Not touch the ground at lean unless they are hinged or pivoted and controlled by a return spring

In CMX it states up to and including pre 90 Folding footrests must be fitted nothing about springs!!

Ted your local club does not require you to wreck your freshly painted illegal swingarm ;D ;D ;D to fit a guard.

BUT your local club does require a bar pad if you want to ride. It is in your local club rules that you signed off on when you joined the local club. Your local club is thinking of your dental costs ;)

I actually disagree with that based on the fact that the club is a member of MA and is bound to follow the rules and regulations laid down by the governing body and if you challenged the club ruling they legally would be left without a leg to stand on.

Much the same as Sup Regs can have special requirements club rules can add extra protection. Many Junior clubs required neck braces even though they are not required under the MOMS.

So......Is it 100% correct to assume that for my entries in the forthcoming Classic Motocross Nats and Classic Dirt Track Nats that -
1: I don't need to fit a rear wheel chain guard?.........My concerns being that I'd have to ruin the nickel plating on my expensive classic frames. 
2: I don't need to fit handlebar cross brace pads? My concerns that as I run Jones titanium handlebars with V cross braces making it difficult to neatly fit a pad.

It's ironic that this arises today as I turned my Cheney and flat tracker upside down during the week to make it easier to weld the brackets needed to mount the chain guard today. I was extremely pissed that I'd have to wreck the nickel plating on the swingarm but had gone to some expense to buy special paint that "replicates" nickel plating but it's still not the same.

Yeah it's amazing that last year it says every bike must have chain guards and now in this years MOM's they do a back flip.  Not only that if you had only read the rules for CMX, nowhere did it state you needed a rear chain guard in last years MOM's.  All those guys who have been busy making chain guards and destroying paint jobs on swing arms are going to be P***ed.

and it looks amateurish and like some sort of afterthought. Surprisingly, some of us take a bit of pride in our bikes appearance. If I don't need it, I'm not putting it on.

I made up ones for my bikes , I see it as a safety thing not a hassle might save your fingers or someone elses one day.
better to be safe than sorry in my book.
I cant work out how they change the rules from one year to the next.
