HI i HAVE A 2000 st1100 and have Avon storm tyres fitted. However the the outside rim of the REAR tyre
is very close to the swing arm and just touches when the tyre pressure reduces slightly.
Has anyone else noticed this ? and if so any ideas so solve would be appreciated.
 
I've been running the STorms almost exclusively for the last 5 years. The fitment is close but I've never had one that rubs. Are you sure you have the proper sized tyre installed? It should be a 160/70-17.
 
I'm going to pull the whole assembly apart this weekend and rebuild just to make sure all is in order.
I'll check the tyre size also. How close would you say the fitment was 1/16" 1/8" to the swing arm.
I have had the bike under wraps all winter and could be the Tyre is slightly under inflated but not to the naked eye.
Very strange.

Look at the my-mc-phoenix.com forum recent enrtry on shock absorber link - member had to cut his swing arm cover away for avon storm to fit.

Not sure what you might think I am on but if one of those spacers is not in the correct location your wheel will not sit where it is supposed to in relation to the swingarm. Sorry I tried to help. Cutting motorcycle parts away is probably a way better idea!
 
The tyre can look close to the swing arm but I would have to agree that it sounds like you may have something re-assembled in the wrong order, or missing, as many folks run these tyres and don't need to start with metalwork cutting to make them fit....... I have run them on two ST1100's with absolutely no issues.... apart form wearing them out and having to change them....
 
Got to agree cutting an extra swing arm protector cover back a bit is one thing. No way would I look at altering swing arm to fit a tyre.
I have an old Suzuki and tyre only misses chain guard by about 2 mm, tyres are fatter than in 1972, never been a problem though - worried at first and kept a close eye on it.

Sorry missed this bit - if the tyre in any way touches the swing arm - dangerous, dont use it- something is wrong with the set up!

I have run 2 rear Storm tires in 160/70 and they fit. I did try a Shinko 170/60 and it was too wide for the swingarm.
 
I've been using the Storm for 2 years and nothing touches or should need to be cut. It is a tight fit.

What side is touching? If the right you may have a spacer issue. If the left then you may have tightened the axel pinch bolts on the left before the axle nut and this can cause the left arm of the swingarm to be pulled in toward the wheel significantly. If this is the case loosen the pinch bolts and you'll see the swingarm spring back to its proper position and clearance will return to norm. BTW.... remember to retighten the pinch bolts to spec.

OK. I have traveled 6000 miles on this very same tyre.
I removed the rear wheel to find the swing arm protector plate at one point bent outward in the same area as the
Tyre outer rim. It looks like i picked up a stone or something which logged in the protector and forced in by the tyre.
The protector plate is very thin so easy knocked back into shape. In order to stop this happening again I just knocked the plate back
so nothing could lodge in their again and sealed the plate so no water/rust could affect the swing arm in the future.

With the bike laid up over the winter the tyre pressure did go down a little and i suspect this made the problem visible. But i never thought
this problem would occur. I had the dreaded thought of something wrong with the bearings etc but only a freak caused the problem. I like the tyres
and please to have solved the problem.
Thanks for all your comments
