I have the same question. The wheels on my ST rotate in the same direction; what is it that makes a rear tire think it needs to be turned around if it is mounted on the front?

Uneducated minds crave knowledge. Not that I have any intention, ever, of trying this on any bike I will ever ride, just curious.

Just like on the motorcycle tire auto tires, that are directional, will have a arrow indication direction.

Tires with a Arrow are referred to as Unidirectional.
Asymmetrical tires will be marked "inside" and "outside".

It's all about tread pattern and how it sheds water and other things like heat.

And back to the original question.
Can the wheel just be turned around?
No it can not.
The Wheel is directional. It has a Arrow showing the direction of mounting.

Is what I have read. The difference between front tires and rears being one is driven, the other just rotates so as a rear is usually driven it sheds water differently to how it would if it was pushed. Hence using it in reverse if it is fitted as a front is the theory.

Of course if it was genuinely manufactured that way, I'd imagine the manufacturers would add rotational information in either direction depending on front or rear use, for some reason they don't!

We are starting to see direction arrows.
Higher end vehicles and any tire sold as "All Weather"
Higher end simply because they tend to use higher end tires.
All Weather because they a designed to shed water,slush, snow, and such.
The first hint their is a direction is in rotating the tires.
The owners manual will tell if the tire goes front to back rotation or if a X pattern is acceptable.

All of this takes two things into account.
Owners read the operators manual.
Owners look at their tires.
Neither has good records in the U.S..

My logic on this is that with MOST of the currently available modern tires that fit the ST the front and rear tread pattern is obviously different. The rear tire is usually some version of a "tractor" tread which cleans/clears itself and benefits from the propulsion of the engine's power.

The front tread is usually a version of a tractor tire turned backwards. The force that turns the front and therefore forces water out of the tread comes from the road surface itself.

It seems fairly obvious and logical to me but I may not be explaining it very well.

Thanks for your direct answer to my question. I run 40 to 42 psi, but I admit that I don't check the inflation as often as I should.

I have been running the BT-45 on all of my bikes for several years and they all have a cupping problem, some more than others. I have run them in the correct rotation and reversed rotation and have found no difference in cupping or handling either way.

I presume that the wheel is not symmetrical along its axis as being the reason why it can't be flipped around 180 degrees. If I had a tire changer I'd simply flip the tire to the other direction.

My first ST11 way back when came with a worn out cupped front tire. When I test rode it....yikes it was very difficult to deal with. Id never seen a cupped tire but figured the problem was the cupping. I almost didnt buy the bike because of that. Id never ridden that heavy a bike before. The handling was truly screwed up especially turning from a stop.

I think the replacement tire cupped also and I was using published inflation figures. Somehow I dont remember I learned to run 42 psi front and back. Never had a problem with cupping since. Ive seen many posts about cupping and many replies about dealing with it by using 42 psi.

I always assumed that was the fix.

I also assume perhaps incorrectly that directional arrows are knee jerk reactions on the part of manufacturers to liability problems stemming from other mysterious issues probably impossible to diagnose. (but I would bet the problems were due something the owner did!) All of a sudden after 100 years of motoring they popped up!

Certainly I used tires other than those listed in the owners manuals without ill effect. Also mixed radials and bias ply successfully despite dire warnings in the OM.

Perhaps I should mention I almost never rode higher than 3/10s in corners, cant remember finding anything but the correct psi in a tire plus or minus and while I did see exactly how fast each new bike would go in a straight line with the throttle pegged when I first got it, that was the only time I did that.

Im thinking the spacers on either side of the front wheel are different lenths to prevent installation anything but one way.
