The other day I realized that I have bends on both of my wheels...it does not effect the riding quality and I did not feel anythng untill I saw it.
Both wheeels have only one side of the rim bent out. Manual say I should replace the wheels but is there any other solution to this? Also the spoke wheel is alluminum or steel?

Check the spoke tension for starters which should be done at the first and second service.

Secondly, is the rim just out of true or is it Bent? Has it had an impact?

I am not an expert, but spoke wheels can be bought back to straight, but that depends on whether it is a spoke tension problem or they have had a hit.

Cheers

if it is not too bad, it can be bent back to shape.

If the rim is bent, there are places that can fix them. Check with your local motorcycle shop. For example: -> ACU-TRU® Bent Wheel Repair

I put a strong magnetic next to my rim and there is a small attraction. Some sort of alloy?

I think the rims are something like $300 or so to replace and relacing those wheel will be fun. Not much room for a spoke wrench and will most likely need to remove the rotors.

As previously requested, pictures would be useful.

Sometimes even if it is severely bent it can be straightened. My son once turned his front rim into a very close approximation of a Taco Shell and some judicious work with hand sledges I got it back to completely round with almost no runout. On the ST with the raised spoke attachment points I doubt this could be accomplished as readily.

KEEP THOSE MAGNETS AWAY from the rotors hubs ... Yamaha have advised this as it will Fek up the ABS sensors...
The rims are an alluminium alloy not Steel alloy. Spokes are plated steel (not stainless), not sure if its nickle or chrome plate.

Thanks for your posts..I will try to get some picture to ID the problem. But it was a hit not spoke problem...and it was a big hit :)) 170km/h got in to a whole and happy to came out a live... I was pleasantly supprized that such a minimal damage occured. Tenere is build strong

VERY VERY GOOD POINT ::024::

On the other hand we need a guinea pig to test out that theory at some point. :D

It's a tough Mutha, These things may still be going in 20 years time when the petrol runs out, all the paint polished off, Lovingly restored by wheel engineers...

Here some pictures if you can see it....only one side of the wheel is slightly bent on both wheels..
y'know, if it was me... and the wheels were still true, and tires not losing any air... I wouldn't worry about it. I rode for years with bigger dings than that in my BMW (airhead) rims. They were tubed though, so considerations are a little bit different.

Not much damage for what sounds like a pretty big hit.

I've had worse bends than that repaired. If the rim isnt creased or split then some one familiar with fixing wheels should be able to sort that. Unfortunately I've only got UK sources to call upon.

It's repairable, but would require a specialist. Tweaking spokes isn't going to do much to fix the dent, but you may need a re-true after fixing the dent. If there is no air leak, and you're not noticing a vibration, you could just live with it - people have ridden thousands of miles with wheels like this.

Yep, it was next to the tire/rim boundary. No where near the hub.

induce a magnetic field into the spokes from a close enough magnet and they will also act as magnets whilst under the effect of the induced field, with each end of the spoke becoming a pole. As one end is at the rim and one at the hub you maybe creating a mag field at the hub end. Obviously strength will depend on the inducing magnet but it doesnt need to touch the spoke to affect it.

I found a place that could fix the dent but they told me that the wheels may get scratched and he does not know how to adjust spokes. how do you adjust spokes? What kind of tools do you use?
I think there is a air leak, last couple of rides I check the air presure and I had to add air every time. So I'm incline to get it fix but also affraid that they may make it worst... :question: :question:

Seeing that you are in Turkey, hopefully you are in/near a bigger city. Try finding a dealer in Jaguars, old Triumphs, or other nicer wire wheel sports cars and ask who they would have straighten a wheel. Obviously, bicycle shops do a lot of spokes, but you're on a bigger scale that approaches the sports cars.


There are two things happening. First is to free the rim and straighten the dent. This is typically done with a press and specially rounded wood blocks.


Second is to re-center and align the rim to the hub with the tension of the spokes. If the shop you found is not excellent with spokes, I'd stay away. They could install worse problems than you have. Spokes are one of those things that a lot of dirt bikers claim to be able to do, some even do ok at it, but to do it right is a bit of an artwork.
