650gs twin cast wheels!
Hi,
I have a 650gs twin which I plan to ride to russia on! Do I need to change to spoked wheels? Some people say they cast alloys will be fine! Cheers! |

On the other hand, it's a hell of a lot easier, and faster, to fix a puncture on a tubeless tire than a tubed one. Yes spoked tubeless are technically available but they're very difficult to adjust the spokes on (or something like that) and no-one wants to touch them it seems. People have ridden alloy wheels around the world and will continue to do so. The V-Strom, for example is widely regarded as a really good bike for long distance touring, and it has tubeless wheels. Of course, it's also recommended for 90% road 10% off-road type driving. So, are you sticking to pavement as much as possible, or are you more interested in finding interesting back roads? |
I recently purchased a F650GS twin for my wife and I'm also looking for a possible spoke wheel solution. Love to hear from anyone that has heard of a wheel set that will fit? All this being said I really think that unless you are hardcore off-roading the stock rims should be fine.

I plan to ride to magadan, taking mongolia on the way! Whilst I don't plan to be making my own MX course round the world, neither do I plan to shy away from off tarmac riding!
Some people say that as long as you adjust your speed with the mind set that cast alloys are harder to repair you should be fine? Cheers, Dave |

I figure since my wife is very petit (115 lbs.), her load on the bike will be kept fairly lite and she rides conservatively the rims really shouldn't be an issue. would be nice to be able to more easily repair them though. |
Alloy Wheels

Attachment 4114I am currently riding my twin thru Africa with the cast wheels, they have been fine mostly. I did hit a bad deep pothole coming in to Nairobi, I was doing about 70kmh at the time and hit full on as my wife did on her XT250 (yes looks like I follow her everywhere) after going about 300m the old bike got a bit loose and you guessed it flat tyre ! Rim had been knocked out off shape on one side, I simply put it on a truck to Jungle Junction thinking I would need a new wheel but Chis there just hammered (delicately) back in to shape and it was fine. Ridden to Uganda and back with no Problems.
I to was a little sceptical of the alloy wheels at the start of this trip, but mine have coped some serious knocks and apart from that once have come thru with flying colours. Also the benefits of running tubeless tyres is a plus in my opinion. Happy Riding, Happy Holidays Cheers Paul:thumbup1: |
Thanks Paul for the info and the reassurance about the rims.

arrived cape town the other week with f650 & cast alloy, 78,000km on the clock, 63 on my rtw trip.
off topic, clearance is your biggest issue with the f650. i like the 10.5 inches on the f800 over the 8 with f650. i used a Co2 cartridge to pop the bead back on after the first dent in the front rim caused a slow leak. second dent was more serious & i had to install a tube. had the dents pressed out at jj's nairobi. note that i only ever damaged the rim when running offroad in rock with low (1bar) pressure. i hit some awesome potholes at speed from time to time while running at 2.5 bar (front) and had no problems. never came close to damaging the rear rim. definately prefer to fix a puncture on the alloy with tubeless. just carry 3 Co2 cartridges & a front tube, rim will be fine. if you damage the rim & have to install a tube and then can't get the rim fixed, buy a spare tube. once i pop the bead on the tubeless my slime pump / compressor won't pop it back on - but you can't carry Co2 if you are flying the bike... happy travels dave |
Riding with Alloy rims

Like Dave says you can bend them, gently back into shape if necessary. I also point out that Dave's problems would've been exactly the same with spoked wheels. The 'real' problem as I see it (and it hasn't happened to me) would be if the alloy wheel snapped. You can't weld alloy wheels (as far as I know). With spoked wheel you could replace spokes and bend the rim into shape. That said it is almost impossible to true a spoked wheel without full factory conditions. The point is if you have a big enough accident or issue then no matter what wheel you are using you would probably need a new one. For smaller issue the jury is out because it becomes a debate about tyres, tubes, plugs and running on low pressure. After 65,000kms RTW so far no issues with alloy rims on my GS, 80% on road, 20% off road. IMO you can ride anything with alloy if you are careful and go slowly. :scooter: On a separate note, I was able with my 12V air compressor to pop the bead back on my wheels (more than once) but when I tried with a friend who had spoked wheels there wasn't enough pressure (displacement to be exact) so I think I will also take a CO2 bulb for this possibility in future. Not for me but for my friends. :D |
I'm starting to think that I should swap some alloys on to my 800, kidding of course but the reassurance that my wife's bike won't be a big problem to deal with is very reassuring. THe tip about the CO2 is a biggie.
The low bike clearance I've always known will be a problem in some areas but what can we do she is only 5.1" with a 37" inseam. |
Great information! We too are planning to ride across Russia (albeit to Vlad) and my wife has just bought herself a beautiful F650GS Twin.
As an aside, I recently swapped the spoke wheels on my R1200GS for alloys for a couple of reasons. The alloys are lighter, they stay true and they're easier to clean. As the spokes on the 12 are already tubeless this wasn't a reason for the switch but it played a factor in choosing the F650 over lowering an F800. |
Ekke,
That road looks familiar is it the Mayole-Marsibit section, I read your blog and got allot of info off it re: where to stay etc. We are doing the Cairo to Cape Town trip, I will have to read from Tanzania on as thats where we head next. Cheers Paul:scooter: |
The main advantage if you are going to swap wheels is that you can use narrower rims which will help more than just using a better alloy or spoked vs. cast.
For the front you can use a F650GS single cyl. hub, on the rear the one from an F800GS (RAD makes a nice billet replacement). I would get them laced up with a set of DID Dirt Star rims in 1.85"x21" front and 2.5"x18" rear for best off road performance and durability, that's what the KTM 950 Super Enduros run and they hold up great. |
The Wheel Truth
Okay I admit it I've become obsessive about the idea of cast vs. spoke wheels. So I thought that I would share the truth that I have discovered. First I emailed a lot of people including dealer service departments, motorcycle tour companies, wheels builders, etc. Without exception they all responded with the same message and that is that the cast rims are not meant for overland touring type travel. The rims will bend or crack under a bike that isn't loaded even on just marginal roads. Mick at compass expeditions has kindly let me know that their 650 twins have had many rim issues and their tour groups ride with no luggage on not overly nasty routes. He says change them if you can.
Solutions aren't cheap but they can be bullet proof if done correctly. Thanks to Woody and Zach at woodyswheelworks.com and also Mike at touratech for correct info on wheel solutions that will work. As stated in the previous post the the hubs are available and excel rims can be sealed to maintain the use of tubeless mounting. Again not cheap but considering the fact that you could easily damage one of the OEM rims beyond repair with zero option to put on a new rim in the middle of you name it, I say its a no brainer. |

You came supposedly on the HUBB looking for advice from people with first hand experience when actually you were only looking for confirmation of your own opinion. Then you're right, go back to TouraTech and your dealer and spend lots of money on changing your wheels.doh Quote:

Let us know how carrying spare rims and spokes for the spoked waterproof hub wheels works out for you. jeiger |
