The moment is the same no matter. The distance to the midpoint on a 525 is wider there for the effective moment is greater. I may have not measured the one of which you speak. I had a stock 525 that was low mileage that I wanted to use on my 1098SF. I grabbed a zvmx 525 master and the pins were .015 inch bigger. The 525s wear better because as you say the bearing surface is larger.

The force isn’t applied at the midpoint of the pin. The force is distributed along the pin where the roller sits. The pin is then in shear at the gap where the roller ends and the plate.

Pins, rollers, and pitch sizes are all the same between 530/525/520 except for width

Yes the force is distributed across the face of the roller. And of course the pin is in shear. There is still a bending force on the system as a hole. What varies relative to chain strength, not size, is the pin diameter and side plate thickness. The rollers ID is then sized as required. Go measure some parts, you'll see.
 
You guys are nuts if you’re considering running a Superstock prepped bike for track days. And $44k for a RACED bike is crazy because it’s been used and abused.

Wasn’t raced, if you read it, it’s their test bike. Having said that I can build a 2025 version of that bike that’s brand new and custom tailored to me for $47k to $50k
 
Testing… raced. Both get abused. How do you know that it hasn’t been raced? Easy to say it hasn’t been raced but you’ll never have proof

Fairly cynical, however. I agree it’s more than I would pay for the bike. At $35k I’d consider it. Depending on the hours on the bike and whether the engine has been or needs to be refreshed.

Making assumptions comparing the same pitch chain in different brands/intended useage is futile. The only thing consistent is the actual pitch, ie pin center-to-center distance and roller outside diameter. The pin diameter, roller shell wall thickness, plate thickness/shape are all different. YMMV

Or you could just look at the tensile strength and life index…
 
Ive never found it to be hard work, sure I notice the difference between lightweight wheels and clunkers but its meh in reality unless you really want to win the trackday! Heavier wheels provide great directional stability and tbh when I go between various bikes I am always surprised by how much I dont really care about rotating mass etc as long as the whole package works. So what if I have to brake a bit earlier or its a fraction slower accelerating? Just pretend youre on a sports bike from the double O's and youre golden 😃

Do you ride your bike at track?

Even my RC 8C that’s 100 pounds lighter is hard work if you are pushing the pace, by the end of a track day your knackered.

Every couple of seconds that you get faster per lap you are increasing the physical demands of riding these bikes at track, and everything you can do to manage energy expenditure is helpful.

Agreed though that a heavier rotating mass with heavier gyroscopic forces makes the bike feel more stable. This is where preference comes in. Do you prefer to dial in agility and give up some stability, or vice versa.

I prefer agility, especially because you can dial stability back in with a few geometry changes and have both.
 
I managed to have a sit on one today. It’s a good riding position - not cramped - and the tank feels narrower than my current bike – not really sure if it is as narrow as the new Ducati but probably. It feels quite slim overall though, and it looks small and quite pretty.

The screen is good, but it looks quite a bit smaller than the new Ducati.

Nice!
 
Also I’m pricing out the HRC stuff and build list for the Fireblade SP.

To get it to close to a WSBK spec it’s about 20-25k on top of the 28k purchase price. To get it to Superstock 1000 spec that you could win races with if you are capable it’s about 10k.

The Ohlins rvp wsbk forks alone are around $20k.

Yeah but I nor anyone else here needs a bike setup that can WIN a WSBK race…meaning you can have it ‘in the mix’ with FKR carts. or the FGR 254’s.

Of note, Hayden Gillim finished mid-pack in Superbike races last season while riding a Superstock Spec Fireblade.

Also Superbike Unlimited has a set of WSBK forks for sale right now that are used but recently serviced for $7500. I considered buying them, but the problem is you need custom-made wheel axles and spacers and top and bottom yolks and all that stuff to use them on the fireblade., cool to have, but none of that would make me faster then just putting upgraded carts and rear shock on the bike.

As an aside, I think this time around instead of Ohlins I’m gonna try the KTech Through Rod stuff.

Weirdly, because I’m a big guy, I like a smaller feeling bike. As long as it’s not cramped ergonomically. That’s one of the things I like about the Fireblade, it just feels like a smaller bike to throw around, but with liter bike power. With the BMW’s I feel like I’m to high off the ground, not low and sporty enough, I like the Ducati better because it feels a bit lower and smaller than the BMW but I still feel like I’m on top of the bike moving it around underneath me. Not necessarily a bad thing.

But with the Fireblade I feel like I’m lower, and that I’m more IN the bike and connected to it.
 
You’d be surprised at how good the electronic stuff is now

Yeah I’m gunna put track fairings and CF wheels on the bike, and a better Brake MC and ride it like that for several track days before doing anything else.

But, I know eventually I’ll go analogue suspension because you have to with the HRC Race ECU that unlocks 30 more HP and gives you all that detailed setup options
 
If you like that feeling, might be worth considering a GSXR1000. And you’d have a lot more money left over for upgrades

I had one, liked it a lot, but the bike felt heavy…incredible torque curve, super stable mid corner, turn in felt heavy and moving the bike side to side felt heavy…great bike but in some ways it feels like it is, an older technology bike

The stock ducati chain that came on the clowncar has the identical size pins and sideplates as a zvmx 520. I just went and measured them. The pin dia is .210 inch. The 525 zvmx has a larger pin and thicker sideplates. The 520 zvmx and the stock ducati chain have .186 in sideplates. The 525 zvmx has .195 sideplates. Apparently I don't have a spare 525 master to measure but it's bigger than the other two. I know this with a certainty because I tried to use a 525 zvmx master to reassemble the stock V4 ducati chain to use on my 1098SF and they don't fit.
