Better to buy a 2nd bike (sportbike) for those rides in the twisties where "flicking" through corners is the name of the game. It's why I have a pre-order in for the new YZF-R9. Whether I actually buy it depends on factors of no relevance here.

I thought about mentioning this but decided to let you work it out for yourself.

You are getting better at this rationalisation thing, young grasshopper.

I like that "young" adjective, being nearly 78.

older than Radames Pera and younger than the late David Carradine

Looks like more than a few here are suffering from SAD.

If by any chance a northern hemisphere dweller is feeling SAD, I can thoroughly recommend going somewhere tropical for at least two weeks. Outside of the tropical storm season in your chosen destination. There's something about that bright sunshine that can "really put the zap on your head"

I've already been to Singapore and Japan this year and I'm off to India again in January.

Much cheaper than a new bike! For the cost of a set of forged wheels you could upgrade to premium economy.

How does premium economy differ from cattle car?

I'm guessing premium economy is the emergency exit seats in Cattle Car on our domestic flights. Your picture appears to be our first class.

..... I never understood the desire to mod from factory equipment unless one really uses the bike for a specific purpose (i.e., turning a sport bike into a track bike). I suppose if you enjoy aggressive riding and the bike you chose was more for fit and comfort but isn’t optimized for how you like to ride, it’s worth it.

Like people who trade out for titanium and carbon fiber but don’t race. ........


It might be the kind of thing that is the same reason as why we ride a sportier bike, or even ride motorcycles at all ... I've experienced all this stuff with bicycle wheels and it is generally agreed all around, lighter wheels do handle better. I have a set of very expensive carbon wheels for my bike and they were much different than the medium grade aluminum wheels I had on before. Believe it or not the flat spokes probably made the most difference IMO.
But titanium and carbon parts do have some practical uses. I run fancy titanium frames on several bikes I have and yes they are very expensive but they basically allow me to carry my water for free .... that is how much weight is saved. And there are no worries about corrosion or metal fatigue at all either.
With the motorcycles the lighter wheel is going to handle better likely. Forged wheels also can be lighter, but it depends on how there made, and what they were made for. Carbon wheels would be more likely to be lighter. Forged aluminum parts are stronger pound for pound which allows them to make the wheels lighter if they choose to do so. But what about the forged wheels offered for the 1600 gt? Why would they offer forged wheels for that bike and not the RS? Anybody know?
I looked in to this when I thought I had forged wheels on my RS and it seems they build the cast wheels to be a certain amount malleable to absorb shock from hitting things in the road like a brick or something like that. And that keeps you on the bike instead of launching you into the air highside or at least the best that I can tell that is what the manufacture is up to. So the wheel is designed to be a high impact shock absorber so to speak. And I'm pretty sure the forged wheel for sport bikes do the same and are not much if any stronger but lighter. And carbon has turned out to be rather delicate but almost always lighter.
On my bicycles I went back to a real high end DT Swiss aluminum wheel (EX471) with Sapim 18/8 stainless flat spokes, mainly for durability. They are slightly heavier than the old carbon Enve wheels but handle just as good and are still much lighter than department store bike wheels still. Most people broke their Enve carbon wheels and now they mainly make wheels for road bikes. They started out in mountain bikes but the wheels will generally break when you have a flat, hitting rocks likely. Now Enve only recommends using cush cores with carbon wheels for dirt riding, which completely negates the lighter weight.
So i'm going to stick with my fancy 719 cast wheels for the foreseeable future on the RS. Like Bear has seemed to rationalized that expensive wheels are probably not too practical with little gain ....
But if one used the RS for track day mostly then a set of forged or even carbon wheels might make a practical difference there .....

I'll bite. What's difference in cross-section profile between the round, flat and aero shaped bicycle spokes?

Well you have round spokes and then flat spokes. And there are different kinds flat spokes with sapim making at least two, Sprint and Xray .... The flat spokes have less wind resistance which turns out to be substantial in my experience. It translates into heavier steering especially at speed with round spokes. And it will likely slow you down some too, overall. When I first rode with flat spokes on the carbon wheels it felt like there was almost no weight on the steering even at a higher speed. You could simply turn the wheel 90 degrees while moving along at say 15 mph plus or less too. As you already know anytime you have more weight on the steering, due to several possible things like worn tires or other stuff, handling is detracted and could become dangerous for sure.
So I don't have bicycle wheels built without flats spokes now at all it seems.

......How does this relate to forged wheels? Asking for a friend......


LOL Well I could answer this with another question; like; What does pics of the inside of a aircraft have to do with forged wheels?

But more seriously, the design of what ever connects the rim with the hub and it's possible drag in the wind while turning would be related to say searching out wheels that handle better and forged wheels. The whole theme of that comment is to point out what I realized after studying the subject more, that "forged" just describes a manufacture process and doesn't automatically mean better handling or lighter weight. It is complicated. If the design is lighter then it will prolly handle better likely. It's just opinions here mostly ....
