Not much to explain. See Photos. I have a similar issue with my 73 Norton Commando, but not near as bad. The grips just get sticky.
I think I excrete acid through my pores.  Not looking good for you Ozzy.

I removed the OEM grips years ago and upgraded to Oxford heated grips. They are an inexpensive replacement. Grip Puppies or similar can also be applied over top of the OEM grips.

That is sooo weird. They look like those old plastics on mouse (computer) rubber. Slowly disintegrating... but on a faster scale? I've never seen anything like that. Even after 41K miles of riding in 3 years and abusing the hell out of that motorcycle.

I'm just saying, not washing the bikes is a good thing. Maybe they are melting but all that dirt and dust and whatnot is sticking back on the surface! :-)

I lived in Miami before Hurricane Andrew. Those pix of your grips look like foam rubber [think Grip Puppies] that has been exposed to a lot of sun screen on fishing rod handles. Are you riding with gloves? How about sun screen?

I doubt its purely climate related or other owners would have the same problem. I'd suspect its something else, possibly reacting to or aggravated by the weather or sunlight. Could it be a cleaning product?  Whatever it is, if something has de-stabilized the rubber/plastic compound of the grips there's probably zero chance of stopping or reversing that chemical reaction.

I know of a Trophy with the stock grips deteriorating in the same way. I removed the stock grips from my TEX when I installed the factory heated grips. The originals are definitely sticky, which is the first observable step down this path.

I've seen this on another bike. My 2008 KLR650 was from the first model year assembled in Thailand. It was recalled because all 4 rubber turn signal stalks turned to sticky goo and fell off. Eventually every rubber grommet on the thing turned to crap.

I've seen many things do this over time. I once had a spool of speaker wire have its insulation turn all gooey after a couple of years, to the point that I could not get it off the spool. Recently, my father had to retire his 10-year-old digital camera because the rubberized coating had gone all sticky. I had a briefcase that I had not used for years, glue itself to the top of a filing cabinet. None of these things were exposed to excessive heat or sunlight or chemicals.

There are some flexible synthetics that just break down over time as if they have built-in biodegradation.

Yeah, given enough time... I don't think it's been that long with this bike's handlebar grips though... I thought for a while whether or not heater systems have a detrimental effect on this, but I run them 4 months out of 12 almost every day... This particular melting case is interesting to say the least.

It might come down to inconsistent product quality -- a bad batch of rubber.

Ive had a few grips do that over the years.  oil and sunlight can do that to any rubber but that's weird.
don't come to a cat forum saying you should have bought a dog.
