‘23 V4S stock forged wheels vs BST wheels

Help Support Ducati Forum:

Dunlop brought out a 120/70 (soft DOT) that's about 10% shorter than the current ones. So I put one of those on a forged wheel and a normal height one on the CF wheel. Then I blindfold you... I'm going to try one at some point. Should turn in more readily. Has to be lighter and that weight is further out yet.

Move along dude, I bought a pair of wheels I like, for very specific performance reasons, that is all.

Not sure whats your problem mate, said to buy OZ in beginning of this thread. Exactly same performance, much higher durability even if you crash and touch the rim.
 
The short version for most people is forged OEM will do fine but if you're inclined to change then get the wheels you like and can afford, it's not going to make a life changing difference. No need to be a Luddite, carbon wheels have proven benefits but there are a couple of minor negatives as discussed.
Performance improvement is always a case of knowing when to stop as there is literally no limit to how much you can spend to get ever decreasing gains FYI MotoGP bikes are only 1 or 2 % faster than WSBK bikes on the same tracks despite millions of development dollars between them, arguing the benefits of carbon vs forged wheel etc is not an argument thats worth winning.
 
Reminds me of arguing the difference between ........ like say 54 DD and Small Tits as in an A-Cup. But both are natural ones of course, not those silicone jobs.
 
big boys slicks are 125/70 and 200/65 now the taller front matches the taller rear.

Some do run the lower front 120 70 with the taller rear....but only 7 people on this site mess with geometry.

the rear 200/65 is only a millimeter or so difference in height from the 200/60 so I didn’t adjust rear ride height for it, but I lowered the front by about 4 mm to compensate for the significantly taller 125/70

That seems a significant difference.

What are pros and cons for using the different sizes to standard?

Geometry changes are required?

Andy and I agree on this (though did he read this or did he actually break out the tape measure for practical experience?)! The 125/70 front and 200/65 rear slicks both grow 2% so no geometry changes are needed. 2% is marginal, not significant. Pros 2% bigger contact patch, sharper profile. Cons 2% heavier, not as stable.

Do some reading first, form some thoughts of your own, and then ask questions… It’s all right here DIABLO™ Superbike - Motorcycle tyre | Pirelli and here www.google.com

Interesting.

No need for links to Google and Pirelli - already aware of their websites.

Are there any issues with fitting tyre warmers under standard huggers with bigger tyres? Not sure that you’d have experience with that, but I’m sure others here have.

Possibly maybe. Depends on your tire warmers, fenders, and stands for clearance. Only way you’ll know is by trying. I know on my FG Gub stand there‘d probably be clearance issues with warmers on OEM 200/60s.

But again, for track days why are you running anything more than an SC3 which doesn’t necessarily need warmers?

No need for practical experience here. Just a good dose of common sense and forethought.

If the 65 is the same height as the 60 that 5 be on the sides. Shorter sidewalls? Profile change?

“I don’t know” would have sufficed. 👍

Where are you seeing the sc3 doesn’t need warmers?

On the pressure chart linked bellow, the only size listing warmer use as “optional” is 100/80. They don’t specify warmer use based on compound at all.

I talked to Chris Maguire at CT Racing (West coast Pirelli distributor) and he said that you can run the SC3 slicks without tire warmers. This was confirmed at the Pirelli tent when I was at Laguna Seca. But yeah, there’s no mention of it on their site just with the Diablo Supercorsa SC (DOT) tire How to choose the right Diablo Supercorsa sc compound

I’m setting it up so my street wheels with SC3 Dots…and the track tires I’ll run next track day are an SC1 front and SC3 rear slicks…expecting cooler temps
 
Lots of guessing here I can see;) I have been running the slicks in 125/70 SC3 for the front and 200/65 SC2 or SC1 in the back this season.
I had to get new warmers as the front did not fit with regards to the very small distance between the (extremely crazy) location of the brake line fixation.
Was running some cheap China model warmer and the upgraded Alpha I got was much thinner.
One thing to take care of is that the brake line fixation under the fender looses and then rubbs against the wheel, I know of one nasty accident due to this...
Another thing I did was to move the ABS connection line to the outside of the fender.
