Hi the spoked rims are aluminium with stainless steel spokes. I didn't do a weight comparison but might slap them on the scales next time I pull a wheel off. If I had to guess I'd think spoked would be slightly heavier due to the addition of a tube.

Thanks for the feedback.

Hi, yes the front is compatible with the front hub from the 650 singles and it uses a more common spoke pattern that appears to be the default for aftermarket rims. The rear needs the F800GS hub then custom drilling and spokes for the size of rim you want.(or entire wheel if you're happy with a 17", 4.25" wide rim). I believe the pattern matches the rear rim from a KTM690, so then you would just need the custom spokes.

PD335 and the fork leg is 41mm. Now the YSS web site only lists the whole upgrade kit if you filter by that model, but if you search you can get to the PD335. I don't know what size adapter you need. yssaustralia.com.au/universal-products/32956-pd-fork-valves.html

@@oacmose281 My bike is a F650GS single 2004. Same size fork, apparently the PD335 are good for mine too. I'll bite the bullet and order a pair, I got tired of vague front suspension. And I can't access that site from my location.

So I ordered mine and they came but the instruction leaflet is just a small page and the oil height is not mentioned at all. How did you get yours? I see something on the site, "Oil height (mm): 140". But 140mm measured from where? Can you post a link with a more detailed manual, please? Also, mine don't have the adaptor collar mentioned in the link above posted by you.

@@rationalityfirst Hi, you'll have to contact the supplier for a model appropriate adapter collar. I'm afraid I don't have a record of the exact size but the supplier should know from the model of your bike. The fork oil is measured from the top of the fork leg (see video) with the fork compressed. I set it at 150mm as per documentation that came with the valves but have since blown the fork seals. May or may not be related but I'm reluctant to make any definite recommendations. 140mm means more fork oil (than 150mm) so I'd put in a bit less then test ride it. If it bottoms out too easily add a little more but don't over do it.

@@oacmose281 I had no mention in my documentation about the oil height, just on the Thai site I found a mention of 140mm. I took it for a few short rides and I also hit some big square bumps and no oil leak for now. the strange thing is that I had different volumes of oil for each leg, just going by the oil level measurement, the left one took less, no idea why.

Glad it helped.

It's a clearance special from a now defunct online reseller and likely Chinese😀. The front is the common spoke pattern so I would expect any Excel or other aftermarket rim to fit.

Happily not. Despite the name it's the 800 twin. But I think some of the 650 singles were made in China. en.wikipedia.org/wiki/BMW_F_series_parallel-twin

I do still have the cast rims but I'm kitting them out with a more road biased tyre and will add disks and ABS rings. That way I can do a quick swap for road rides. Sorry.

No the rear wheel from the old model F650GS single won't fit, it has to be from the F800GS. A pity as second hand old model hubs seem to be easier to find.

I really need to log in more often to check the comments. The updated model of this bike, the F700GS, had two disks on the front but that means the spoked hub from the older model will not fit. If you want a spoked front wheel and two disks it would be easier to just get the F800GS.

@@oacmose281 yeah You're right. Thanks for your response. : )

Hi Lewis. You'll find it good on any small potholes and edges where the standard ones are harsh. It doesn't really help with the extra weight of going two up. Might be worth replacing the springs to help with that.

Hi Peter, glad the video helped. The real benefit of the valves is the plush action in say the first half of the stroke. Compared to standard that harsh action from square edged ruts just disappears. They are not really going to help with the bottoming out, however you could remove less or even none of the spacer and then there will be added preload. Might be worth checking your oil levels. I added a little extra after putting it all back together because it bottomed out too easily. More oil means less space for the air to compress at the end of the stroke so less harsh bottoming. But don't over do it as I think that can lead to too much pressure on the fork seals. The full YSS kit with new springs and adjustable preload caps may help address the bottoming. Regards Neil

Yes, that is the sacrifice. There are some options to seal spoked rims but I'm not sure it's worth the effort.

@@oacmose281 so true!

@@oacmose281 Tire pressure sensors? Or is there a way to disable the RDC? Looking awesome!

@@ernielo4134 My bike didn't have the tyre pressure sensor option so I didn't have to worry about it. However I'm betting that because it was an option it will be easy to disable.

Hi Tony, well spotted. Custom built spoked wheels using an F800 hub on the rear with a 2.5/18" rim, and an older model F650GS single hub on the front with a 1.6/21" rim. Both hubs fit without modification. I also just recorded a video detailing this and will put it up soon.
