Not sure what you mean by 'recess cut' in the side, but here's a Yamaha website that sells a 428 pitch, 60 tooth sprocket;

Shipping will probably be a bitch though...

I've found TALON brand sprockets that are 428 60T over on eBay sold in the past. Usually from private party.

I am also unsure of the "recess cut" option you are referring to. However, I just ordered myself a Sprocket Specialists 70T. They offer 4 options including:

Saw Half (Split)
Link-Lock (Split w/ Link)
Hot Slots
Ultra Lite

Maybe that is one of the options you're looking for? Of course, I must mention that these are aluminum sprockets - not steel as you requested. This company does offer a hard-anodized finish for $25, though. An option I felt was absolutely necessary if aluminum is the only option.

Maybe a picture of your old sprocket would help us understand what you're talking about?

Thanks all
TW Brians pic is the type of sprocket I'm looking for..
I have found a few in aluminum but I need steel..
I will be running dual sprockets in the rear with a single counter sprocket...
(Unless someone magically sends me a 14-15 tooth dual counter sprocket.
Sadly the manufacture of this counter sprocket is beyond my skill set..Hint-Hint )
With the chain running out of alignment I'm afraid aluminum sprockets
Will just wear to fast...
WOW An anodized aluminum 60 tooth sprocket from sprocket specialist is $131
THE SEARCH FOR THE PERFECT SPROCKET CONTINUES

So what did you settle for
Smaller steel sprocket?
Aluminum sprocket

The diameter for the circle of bolts on the TW is 80 mm. The Dubbo sprocket is 123 mm. It won't work.

I guess I should have stayed with the 14 tooth counter sprocket and went 47 And 55 rear ..
What's done is done . I'm happy with 15/50 on the street..
I doubt that 15/55 would be worth the expense or effort for a dual sprocket set up.
It would be barely lower then stock.
It should only be about two teeth lower then stock about 14/52..
Is this correct ?????

Honestly, it terms of acceleration and even off road ability, going from a stock 50t to a 55t didn't make much difference. Top speed didn't change all the much either. If I am going any distance I will look at the tach and go 8600 to 8800 RPM and let the speed be what ever it is which I think is around 60 mph.

Off road 1st gear is so low anyways there is plenty of torque.

What I did find to make a noticeable difference was when I had dual sprockets and going from 45t to 55t but I found, for me, swapping the chain back and forth to be a PIA so I settled for the 55t. It would have been OK if I only needed to remove or add a short section of chain but I found I had to slide the wheel forward of back for the proper chain slack and I really don't want to do that kind of thing unless I am home.

Hey Tony, what a surprise. Trail side sprocket/chain adjustments can indeed be a P.I.A. What had helped me minimize that, was making and using a 'crutch jack'. Believe a fellow named Bruce first brought it to the attention of the forum. Simple to make and easy to carry. With your kickstand on one side, and the crutch jack on the other, the rear wheel can be completely off the ground to move forward or back more easily. Still a process, but the crutch jack really helps along with a stock Yamaha axle wrench gusseted to allow tire irons to be used for leverage. Stopped by to see if forum activity was remaining robust given the 'germ situation'. Given my age and issue with emphysema, i am keeping my head down and staying in the shop. Take care.

Remember, with an aluminum sprocket, you can flip it when it starts to wear. OR set up so the aluminum 60T is more in line with the CS sprocket, and the steel ??T second rear sprocket in steel should hold up.
Keep an eye out for a whole second rear wheel assembly. One for street, one for dirt. You could not only have sprocket options, but tire design as well. I know it would cost more, but It's not a problem to swap out a rear wheel assembly in your garage. No worse than a dual sprocket change with the chain, adjust chain slack, etc.

Anyone remember the name of that sprocket company that made Aluminum sprockets with a riveted on steel ring for the teeth? Light weight AND the durability of steel. Stealth or something like that. I've used those on my enduro bikes. Held up great on a Kawasaki KX250 and a BMW 650 Dakar.
EDIT
Here it is! Supersprox;

Heck if I was going that route it would be just about as easy to just change the sprocket if the wheel was off.lol
I'm looking at riding blacktop 100 miles to the trail. Playing on the trail for a few hours then heading home
