    Has anyone used balance beads in the F700GS OEM rims, I'm wondering if they are compatible with the valve stem on the front and the tire pressure monitors? Can you install them with the wheels mounted and on the bike? Also which brand to buy?

    I can never seem to get a decent shake when it comes to mounting & balancing wheels and tires,,.

    I recall the OEM setup to be pretty good with very few wts from the factory, two on one wheel and none on the other,,. Now I have 12 weights on the back and six on the front and I find that starting at 80 mph the front seems very course & with handlebar vibrations and gets progressively worse as the speed increases,,. 80 mph is the point where the engine RPM is getting up into the 6000's so maybe this is a factor as well,,.
    Not sure if I'm expecting to much? ,,,,,,,,,,Comments would be welcomed?

    The dealer used to try to sell me on whatever they put in the tires so the stuff may work. I just never bought into it.
    There are plenty of folks that adhere to the science of it. Worth a try, I guess. The tire shouldn't get funky at 80 mph.

    Thanks

    Yes I've read enough reviews that they sound worth a try, at least this way I can run the bike, switch the balance to the beads and run a test just to see the difference, other wise I would wait for the tire change,,.

    I would still like to confirm if they can be installed past the TPMS sensors?

    The TPMS in my R1200RS wheels looks too large to let anything past it in my opinion. On my bike it sits right in the middle of the center of the wheel rim.

    Yes, Richard, thats my concern,,. I think you might have to break the bead and put them inside,,. The kits come with stem removers and certain tools however I'm not sure if there's a get around the sensors,,.
    If anyone has put beads in a F700GS OEM rim I would love to hear from them,,. Cant find anything specific on the net,,!!

    Thanks,,.

    My guess is that breaking the tire bead to insert the beads would be what you would need to do to insert them into the tire. That might be possible with the wheel still mounted on the bike using a large C-clamp to break the bead on one side of the wheel, while placing a piece of wood on the other side to protect the wheel rim. The rear tire's bead can be a bugger to break, though. Unfortunately, I have no idea where the TPMS is located in the F700GS's wheel and how large it is. Perhaps checking out the bike's parts fiche on the Max BMW site might provide a hint to its location and size. Or maybe looking for a YouTube video regarding how to replace the pressure sensing device's battery might be a better idea.

    Looks like there is a small hole that protrudes right through the sensor?
    same as the 1200GS

    The TPMS on my R12RS looks different that that. The valve is located in one of the wheel spokes, while the pressure sensor (which looks to me much larger than in your photo) assembly is separate and attached to the center of the wheel rim below the spoke with the valve. BTW, the valve assembly can be unscrewed with a deep metric socket, which leaves an empty hole in the rim. There is also something odd about the valve assembly. I have been unsuccessful in removing the valve core with any sort of tool. Each valve assembly cost $7.50 and comes with blue thread locker painted on the screw threads.

    So it appears that BMW is not too interested in standardizing the TPMS used in their wheel rims on their different models as the device that you show is completely different than the one in my RS. My guess is that what you show is more likely what is in your GT than what I have in my RS. If that is the case, then the TPMS is located in the center of your rim too and would appear to interfere with the movement of the plastic balance beads. However, I have no idea if that would disrupt any balancing that they might do.

    Yes Richard, the images were from the Al express,,,, they have dozens of different venders for as little as 10 ea,,. They state its for the F700GS as well as the R1200GS I found a guy with a 2017 R1200GS on a thread who had asked a similar question to mine,,. He eventually tried it and said with a lot of farting around, tapping and so on he was able to get the beads into his wheels without breaking the beads so I suspect it might be doable given the right technique,,.

    A couple of obvious differences are the spoked wheels on the 1200 and the 700 has that crazy sideways off the rim spoke mounted valve stem,,. I'm still holding out hope for someone that has actually done it on the 700 before I order beads and what ever else is required?

    I thought I might have a tire/wheel balance issue as well but pulling in the clutch at top speed killed 90% of the vibes.....leading me to look at the engine as the culprit. I can run smoothly to about 5k rpm / 140km/hr, then it gets progressively worse. Or, if running downhill, much faster without vibes.....so again...suspect is the motor, specifically the throttle position. I have a supply of beads in my shop but haven't installed them as I suspect they would clump over time. I've read that a little air pressure behind the beads assists their entry into the tire.
    Friend uses the Ride on product, says he's happy with it.

    Thanks Anjelli,,. Now thats interesting, I've never thought to pull the clutch lever but will give it a try,,. Occasionally I've forgot to go into 6th gear and looked at the speedo when this balance phenomena occurred only to discover it was occurring at a lower speed, the condition improves with the upshift so I've been somewhat aware that the engine RPM is a factor,,. I think a combination of things (speed, road surface, engine rpm , tire condition & style ) are all factors,,. I notice this on my Ninja as well?
    PS
    Interesting to know someone else is on the site from the Lower Mainland,,.
