Funny that BMW did not make ONE CHANGE to F800GS suspension despite the forums being overloaded with complaints about those nasty Showa (correction: Marzochi) forks. What is UP with that? You can see just buy looking, the GS forks are too small for a bike that big heavy (500 lbs.) I thought sure BMW would go with a big WP 50mm fork on that bike. At $15,000 ... it should have premium suspension, IMO.

The Kayaba (KYB) forks on the DR650 are a damper rod design still used by many current bikes. I would not call them "CHEAP". First off ... Suzuki had the vision (with good advice from Rodney Smith, who helped develop the "new" DR back in 1995) to up grade to beefy 43mm fork. This was a Motocross size fork back then, so quite a big step up. But Honda led the way and forced Suzuki's hand with similar forks on it's XR650L, introduced on 1992.

Look at what the KLR uses (smaller KYB) ... and F650's BMW's crap 39mm Showa fork that can snap right off the bike! Now THOSE are cheap forks! I've never heard of a DR650 fork breaking off the bike. The KLR forks are also under sized for such a heavy bike, IMO. Perhaps the "new" ('08 onward) KLR went bigger?

Sure, the KYB internals on the DR forks are a old design by modern race standards, but the basic fork is high quality, good sized tubes, plenty of travel for a dual sport ... and if set up correctly (as you documented in your post!) it's not half bad for a Dual Sport bike.

Will it match the plushness / performance of current Big Piston 48mm forks or SSF (separate fork function) or Kayaba's latest 48mm PSF forks (pneumatic spring fork) used on current Moto Cross bikes? All these latest innovations out pace the DR KYB item by a mile. But then, most of us aren't jumping triples or hitting the whoops at 60 mph.

As noted above: Proper set up and fine tuning are everything. No one set of valves can work a miracle by itself. It's getting the perfect combo of spring rate, preload, valve (either Race Tech or DDC), oil weight & height ... all matched to rider weight and skill level/riding style.

With Race tech, you can use the various valve springs on the valve for weight/riding style ... so even more tuning. Which valve is better? Only time will determine this one.

All this "fine tuning" involves fiddling. But once it's set up ... you should only ever have to change fork oil once every year or two.

Well, sitting here at the pub after trying for 45 min to get the master link on with the washer method, I am giving in and buying a chain tool.
Looking at this one:

Those F800 things they call suspension forks are "Zokes". The big problem is not only are they crap but BMW spec'd them so they couldnt even be modified or improved and they hydro lock bad. To improve them you have to gut them. I tried everything there was in 08' when the bike was a new model to improve the fork. Not sure about now but then it was slim pickins.
The DR forks are even better then the Zokes on my 610 which also were like two 2x4's.
I'm not a fan of Marzochi forks that's for sure.

You may want to get a combo breaker & press tool so you can easily drive a pin out when it's time to replace the chain. As others have said, it's really a good idea to use a rivet style link, so you may as well get a combo breaker, press & rivet tool.

The pedant strikes again!
Christ on a Rubber crutch Derek ... give it a frickin' rest! There are AT LEAST a half dozen companies using the Vice Grip name.

Did you buy yourself a DR650 yet? Hopefully one that needs a new chain and sprockets. Have at it my man ... lets see how you do!

What is different about changing the chain and sprockets on a DR650 vs. every other bike to an extent that I should have trouble?

On the DR I can change the front sprocket out with a flat blade screwdriver. On my ZX6R it took a breaker bar with a 3 foot pipe for leverage to undo the sprocket nut.

LT Racing, Les made my 50mm behave like suspension should. Give them a jingle if you haven't already gotten your's sorted.

BTW, I'll up your 2x4 and raise a 4x4! Like solid rods in the rocks.

Good lord man give it fucking a break!

They are spelling it vice grip vrs the correct viSe grip...yet everyone knows it was a spelling error and understands the point here none the less.

Your post is gonna cause 2 pages of arguing now and it's useless to the DR community!

My mistake ... I thought BMW were still using Showa forks on the F800GS.
Sorry. Some guys I know have done OK with the Marzochi Shiver forks. Mostly on Huskies and some Aprilias. But they ALL had them reworked ... I'm short on details.

Usually it's a Marzochi fork mated with a Sachs rear shock? I forgot what Shock the F800GS uses. Sachs? WP? ... or? I could find NO DATA on what the stock F800GS shock is.

F800GS guys I ride with Ohlins or Wilbur's. Most have sold off those bikes and gone either Tenere or KTM990.
