12 posts in this topic

OK TTers. my new fork springs will be here soon for my 650r. I ride in the AZ desert mostly trails and the street. My question for you all is which fork oil type and wt should I use for my area?

Thanks, Eric

I use Golden Spectro Ultra Light 2.5wt suspension oil.
do any other manufacturers have ultra light weight suspension oil?

There is only one Spectro dealer in Wyoming and I currently have Bel Ray 10wt (way too heavy :banghead: )

I use Golden Spectro Ultra Light 2.5wt suspension oil. It's real lite and gives a plush ride. It doesn't fade in hot weather at racing speeds. Maxima Light 3wt 75/395 weight is cheaper and is real close to the same "Feel". If your not riding in hot weather, racing then Golden spectro Cartridge fork fluid in light works well also. It's 85/150.

I have used the Ultra Slick Suspension fluid by RaceTech US 1 but, it is tooooo expensive.

Don't use Bell Ray; it sucks. It's hard on seals.

I use Mobil 1 synthetic ATF in my forks. It is nice and light and lets the suspension move quickly. :banghead:

Tranny fluid is 7wt suspension fluid and we used that for years in the XR600R suspension front and back.

I'm not sure either but I couldn't believe it was on purpose that they put it in there. Seriously I was shocked.

The stuff that comes in the 2000~2004 bikes is not the same stuff you by off the shelf, that says, Honda on it. The stuff that come in the bikes from Japan has animal by-products (whale oil) in it. Or salt from the sea air gets in there...whale snot is the official name for it.

I was appalled. Luckily, it wasn't a lot of extra work to replace the dry and pitted steering head bearings while I had the forks off to drain the factory mucus. Those bastards!
