GSA wheel alignment

[Bungy]

It was very evident watching my bike on the rolling road/dyno yesterday that my rear wheel doesn't run true. This confirms the need for a lot of balancing weights on the last 2 tyre fitments. My main question really then is should this have been noticed when the dealer fitted the tyre or on the 12k service? The bike obviously had this when supplied to me as the dealer fitted the first set of enormous weights. Is there a tolerance for wheel run out I can check before forwarding my concerns?

I am assuming your GSA has spoked wheels?
If it does then I would have thought it could be trued like a giant push bike wheel.
In my opinion it should NOT be untrue at all.
If it was mine I would be looking at getting it staightened..
Maybe someone who does classic car wheels could help if you dont want to enrichen a BMW dealership.

Are they spokes?

If so it's likely they're not true. Noticed my rear was way out on a rolling road, fitted a set of cast wheels and it was like riding a different bike!

Yes they are spokes. Special'ns too. They have a small locking grub screw in the centre so take care. If the bike is new BMW warrantee the wheels. You can true your own wheel but it isn't for the faint of heart and can be a complete prick to get the rim back /right. Typically you can't pull a wobble out of a rim (such as on a bicycle rim), as the rims are are so tough. Go check the spokes by tapping them with a screw driver to listen to a nice tight ring note....and they all have to be exactly(!!!!) the same note.

They are spokes and I have heard that it is rare for them to be true and some of the vibrations from the bike are sourced at the wheel. And I thought it was all coming from the engine.

There will be a wheel run-out tolerance. Talk to the dealer. Hagons offer a cross spoke wheel service.

I had awful vibration at motorway speeds, after a session at Hilltop watching the wheel move both in and out and up and down I hoped it would just be the rear but the front was out as well. No off roading, no dinks and no loose spokes, vibration wasn't there when I bought the bike. Hagen wanted £250 per wheel and due to how the wheel is setup won't guarantee the wheel will be true when finished. Bought a 2nd hand set off casts off here with good tyres on for less than the cost to rebuild. And they look better (in black) IMHO. Whether they'll last the Dalton next week is an other matter!!

If you've got Tyre Pressure Sensors in the wheel, you're likely to have quite a lot of weight opposite the valve to compensate, so bear that in mind, mine had 55g front and rear from new.

I have a pair of GS cast alloy wheels in gloss black for my GSA. I use them in winter because the wires don't like the salt up em.

Both look good with identical handling either way.
