Title: Expandable Foam
Post by: BigGreenMachine on October 09, 2006, 12:56:57 AM

Looking to do this trick and need to know the kinda foam to use. Would MONO foam work you think?

OK well MONO is the brand name of the foam and its basicly used to seal cracks from air leaks. It expands in the cracks. What I want to know is would it be suitable as a vibration killer inside the frame of my trike once the 500 is installed.

Sorry for the confusion.

Do you mean the squirty builders foam that expands in gaps.
Often used to stiffen up round doorframes?

I have heard of someone usingh it in their handlebars to dampen vibrations down but personally have never tried it myself.

Good luck anyway regards Scott.

My brother put it in the frame of his Aluminum CR500 and says it makes a difference.   I don't know what brand of foam it is though.

 I read on a Red Bike forum about the foam trapping moisture in the frame and causing
corosion problems.   Just something else to consider before trying this.

Arigato, thanks for the info. I have a chunk of that MONO foam I nabbed off the shed wall a few seconds ago. Its pretty solid and seems like it would absorb a lot of vibration.

I know my 250 Tecate (no counterballancer) would rattle my teeth when I rev'd it up but you wouldn't really notice it after a day of riding other then the fatigue from holding on. Hoping the foam kills a good bit of vibration.

As a side note, I know that some grasstrack car racers use squirty foam in the doors, between the inner and outer wing and various other places to stiffen up the cars as they are not allowed to armour them.

I seem to remember someone rally prepping a car years ago and using some squirty foam to stiffen it up also.
