Does anyone know the internal difference between 2002 and 2006 forks.

Only thing I know for sure is that fork travel went from 200mm to 170mm on the cast wheel bikes

Anyone?

Spring rate, air gap, valving?

Sorry, Brad. Can't help because I'm not a Girly (with or without asterisks :icon_wink:) owner. Someone is sure to chime in.

Apart from the travel difference already mentioned I can help with 1 out of 3 of the above, air gap on 2002 bike is 107mm, on 2006 bike is 146mm

Run mine with Ohlins springs and 720cc of 15wt but I've sticky 17" front tyre to lean on not a 19" so pick what ever bones you want out of it.

Side by side comparisons.  The 2006 fork is 37-40 mm shorter than the 2002.  That will get the front end down plenty.

The lower casting is identical.

So with all the talk about ATF being used as fork oil and all the time that's passed, what is the conclusion?
The ride might be fun, but in the great scheme of things, it's the destination that counts.

ATF is ok if your happy with the stock damping, mine had Hyperpro Springs & 15cwt fork oil which can be a bit harsh at first in cold weather. The Ally wheel Tigers had a stiffer set up to start with anyway compared to the earlier spoke jobs.

Thanks, I just decided I'd better stick with factory recommended 10 WT.

Ah..... but.......  which 10W?   

I can only talk from personal experience.

I loved the handling of my Girly, but after doing the fork service and using the recommended weight (10W I think, from memory) it handled like a pogo stick.

After doing some research I found that unlike engine oil,where numbers are exact, damper oil "weight" is a notional value and every make differs so what then becomes important is the viscosity. After more research, I found a very good Aussie spreadsheet that compared the viscosity of various oils and it turns out that (again I'm doing this from memory so you night want to check) Silkolene Pro 7.5W is almost spot on the same as the Kayaba 10W recommended by Triumph.  Another oil change and peace was restored.
