MOMS new rule - All Disciplines
« on: February 24, 2012, 04:42:21 pm »
Hey Guys...see the new 2012 rule as follows :

12.8.8.6 A chain guard made of 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

This will mean that Classic Motocross must comply..will mean some work for many... :P

Well..if you can get a hold of a "modern" bike chain guide / roller assembly.... they are closed (generally) along the bottom...this may help as an idea...

What bikes don't have these from factory? All of the old Yamahas do, everything with long travel do...

Change the record Wally, I know who you're shooting at and it may have been funny, once.
Dirt Track Sliders never had them from original, from memmory I can't recall any of the early MX style bikes that were used on DT having them either, they were removed or never there.
I understand where they're coming from, but really, what is stopping someones hand from going into the spokes of a wheel? ??? ???

a chain tensioner isnt a factoy finger guard  most are too far away from the sprocket to really count as a cover.

Maybe it's a disease that's drifted in from overseas, from the '09 Antig catalogue

This rule has been in RR for some years now, and some Historic RR bikes chose to fit them also.
The rule is here to stay, so it would be a good idea to make something that looks a bit professional tan ice cream bucket plastic or coreflute.
Aluminium ones are easy to make and look good.
There aer ads for RR type ones on the 2010 MOMs pages 140 & 149

The first Elsinores and RM's had just a small single roller chain guide. In most cases a modern chain guide (genuine or aftermarket) will bolt on without much hassle.

Well there you go Al, now that you've pointed that out the modern Speedway bikes have something similar to that.
Probably a good idea but really, how far do you go?
There is a Speed limit on MX, soon there'll be an age limit & we'll all be f*#@ed.
Thanks for the PM Walter, what I was talking about was the re-curring " Minibike Mum " reference.

Yeah, OK. http://www.theowencollection.com/73Elsinore.htm

A small piece of rigid metal or plastic sheet would easily make a CR or RM/TM chain guide comply with the new rule.
